Abstract

This proposal, prepared by students in the Dept. of Earth and Space Sciences (ESS), seeks funding for airborne mapping systems for precise geospatial data collection. High-accuracy geospatial data is essential for numerous Earth science disciplines, and the proposed tools will enable the acquisition of data with cm-scale accuracy in hazardous, inaccessible, and/or spatially-extensive regions. Four different UAV platforms will offer a wide range of survey capabilities and will accommodate users of all experience levels. This technology will provide UW students with the tools and skills necessary for modern geospatial data acquisition, processing, and analysis. These skills are essential for cutting-edge geospatial research and future careers in a rapidly-expanding and rapidly-evolving industry.

Category Justification

We are requesting funding in the Frontier Technology category. Airborne mapping systems are a new technology with the potential to transform the way high-accuracy geospatial data is collected and the way we study dynamic Earth processes. This technology will provide UW students with the tools and skills necessary for modern geospatial data acquisition, processing, and analysis. These skills are essential for cutting-edge geospatial research and future careers in a rapidly-expanding and rapidly-evolving industry.

Background

Unmanned Aerial Vehicles (UAVs) equipped with consumer-grade cameras can be used to map the terrain they fly over, generating high-accuracy topographic data. Accurate topographic data is necessary in numerous Earth science disciplines; however, there are frequently limitations in the resolution and coverage of available data. Purchasing automated, airborne mapping systems for the University of Washington would enable fast and easy acquisition of cm-accuracy topographic data, enabling new science and giving UW researchers an edge in providing answers to previously intractable research questions.

Over the past decade, technological advances and increased consumer demand in UAVs have greatly expanded their scientific applications, reduced their price, improved their safety, and made flying them much easier. Right now, civil and industrial UAV applications are proliferating in areas such as science, business, agriculture, and cinematography. Investing in UAV equipment will help ensure that the UW is at the forefront of this technology, generating expertise that will pay research and educational dividends now and in the future.

Several ESS students have substantial experience building and flying UAVs to map terrain. In 2014, ESS students successfully completed two UAV surveys of Easton Glacier on Mt Baker separated by two months (see results: ftp://pscftp.apl.washington.edu/pub/forDavid/shean_GISday_2014_sm_opt.pdf). For each survey, we flew a UAV over the glacier, collecting photographic data that was then processed to generate a 3D digital model of the glacier. Quantifying the difference in the glacier over the two month period revealed ice loss, crevasse expansion, and evolution of the river network downstream of the glacier. Repeating this process in the future will allow us to build a long-term record of glacier health in the Cascades, contributing to fundamental glaciology research and providing insight into Pacific Northwest climate change. There are many other promising Earth science applications of this method (see list below). The existing in-house student expertise will be invaluable for helping other students learn to use the UAV platforms we are requesting and to apply this technology to new research questions.

The airborne mapping systems that we are requesting will allow students to quickly and easily acquire high-accuracy geospatial data. The relatively inexpensive, commercial mapping systems we propose purchasing are automated and will fly and photograph specific routes that the user sets prior to the flight. This means the user does no or minimal flying, thereby simplifying the data-collection process, increasing the safety of people and property, and reducing the likelihood of gaps in the data. While it is cheaper to build these mapping systems from scratch, the do-it-yourself route requires in-depth knowledge of aeronautics and electronics that presents a barrier-to-entry for many students. Acquiring pre-made, turnkey systems will help students leverage this promising technology without having to wield a soldering iron.

The range of research applications for airborne mapping systems is broad. We offer a summarized list here:

Applications for ESS students:
• Glaciology (ice dynamics, mass balance, kinematic-wave propagation, calving-front retreat)
• Landslide studies (slope stability, volume estimation, landslide frequency, snow avalanche studies, hazard assessment)
• Hydrology and water resources (snowpack thickness monitoring, watershed analysis, groundwater flow modeling)
• Volcanology (volcano deformation, active lava-flow emplacement)
• Coastal cliff erosion (wave erosion, cliff retreat rates)
• Geomorphology (river and hillslope studies)
• Sedimentology (stratigraphic mapping, clast size/volume, paleoclimatology, paleotopography)
• Structural geology (mapping folds, faults, joints, veins)
• Neo-tectonics (active fault displacement, ground deformation, paleo-seismology)
• Planetary geology (analog studies of features/processes on Earth to interpret observations of Mars)

Applications for students outside of ESS:
• Forestry (biomass estimation, canopy height and classification, fuel estimation)
• Ecology (biodiversity, vegetation health, wildlife habitat, vegetation migration)
• Civil engineering (surveys of structures, landscapes, etc.)
• Archaeology (surveys of archaeological ruins)
• Architecture (landscape mapping and assessment, building degradation)
• Atmospheric science (weather observations)

Benefits to Students and the University

Remote sensing is becoming a major method of acquiring high-accuracy geospatial data more economically and safely than traditional in-field methods. The technology fueling remote sensing is ever-evolving with newer and better equipment. For the UW to stay on the cutting-edge of research, state-of-the-art equipment is needed.

The UAVs will allow visual data collection for several disciplines in the Earth and Space Sciences department. They will primarily be used for creating high-accuracy digital elevation models using Structure from Motion technology (a form of photogrammetry). This technique will be used to bolster research on glacier changes, landslide hazards, river migration, land use, and much more (see above list).

The SenseFly eBee is a simple, lightweight, and reliable mapping platform. The straightforward flight planning and autonomous take-off, surveying and landing requires minimal training. The 3DR Aero-M is capable of covering large areas (~250 acres for ~40 minute flight time) with greater payload capacity. The 3DR X8-M is an octocopter with redundant motors that can survey smaller areas (up to 25 acres) or vertical surfaces, with the ability to take off and land in tight spaces. The DJI Phantom 3 Professionals are mapping quadcoptors that can also survey vertical surfaces and take off and land in tight spaces. This platform is extremely easy-to-use and will provide a great starting point for beginning pilots. In addition to mapping, it will also be used to train users so that they can graduate to larger and more complex platforms, such as the X8-M.

The UAVs we propose purchasing will enable fast and inexpensive geospatial data gathering will allow UW students to choose exactly where, when, and how often to survey. This will facilitate more precise and targeted studies of dynamic Earth features, which will strengthen the research of UW graduates. The UAVs provide a safe alternative to field work in dangerous or hard-to-access areas, increasing research possibilities, education, and collaboration. The UAVs will also establish the UW graduates as having expertise in state-of-the-art technology, adding to the UW’s prestige.

As of winter 2015, the ESS department consists of 157 undergraduate students and 90 graduate students (research and MESSAGe). Annually, about 50 undergraduate ESS students attend field camp where they map lithology over several square miles of terrain. The UAVs would be extremely useful for students attending field camp by assisting in mapping the terrain’s lithology.

Currently, there are specific projects within the ESS department that would greatly benefit from access to the UAVs we are requesting. Tait Russell, an ESS graduate student, is researching the use of UAVs for gathering geospatial data of active landslides. The high-resolution data that could be acquired with the UAVs we propose purchasing would enable Tait to create realistic models of active landslides, contributing to hazard assessment in the Northwest. Amanda Ong is also researching the stability of slopes in the region, focusing on the extensional cracks that cause unstable coastal bluffs to fail and fall. Mapping these features with the UAVs we are requesting would allow Amanda to safely complete her research without having to risk rappelling down unstable bluffs. Keith Hodson, another ESS graduate student, needs high-resolution topography data for his research on geologic structures and landforms. Currently, Keith is forced to cobble together patchy solutions to complete his research. Dedicated UAV mapping systems would both streamline Keith's research process and improve the quality of the data he has access to.

Departmental Endorsements

Recent advances using airborne photogrammetry have revolutionized mapping the topography of earth surfaces. My primary interest is mapping changes in glacier thickness and hazards from snow avalanches, but the system is also applicable to mapping hazards from landslides and volcanoes. Open-access image processing software is available, and so acquisition of relatively cheap UAV's will give our students access to cutting edge technology that will provide our graduates with state of the art expertise.
I strongly support this proposal.

--Dr. Howard Conway, Research Professor, Dept. of Earth & Space Sciences

================================

I am writing to express my full support for the STF application to acquire turnkey mapping UAVs for student research and training. This would generate tremendously exciting opportunities for all students in Earth and Space Sciences, and would facilitate UAV data collection that is the cutting edge of modern field research. As a glaciologist, I think that the application of UAVs to collect data on glacier change is truly transformative. By easily and inexpensively imaging the glacier, we now have a chance to understand ice dynamics on spatial and temporal scales that were inaccessible before. This data is critical to evaluate the impact of significant glacier retreat seen in Washington State. By making their own instruments, David Shean, Perry Spector, Tait Russell and other UW students have become the leaders of these efforts in the Pacific Northwest. I believe that this is a revolution in how glaciers are monitored, and how we address scientific questions around glacier change. If this proposal were funded it would provide these tools to anyone interested to apply them, which would surely transform our understanding of surface processes across different environments. The students leading this proposal are exceptionally skilled using and developing these instruments and have already trained many other students in their current pursuits. This type of research embodies the UW spirit to "be boundless".

--Michelle Koutnik, Research Assistant Professor, Dept. of Earth & Space Sciences

================================

To Whom It May Concern:

I am writing to strongly endorse the Student Technology Fund (STF) proposal for acquiring commercial Unmanned Aerial Systems (UAS) for use in mapping, surveying, and surveillance applications. Our lab has worked with these types systems for years and until recently, most of the solutions were prototype research platforms that were not suitable for field deployment or usage by untrained operators. These were complicated systems that required intimate knowledge of their construction of operation. The UAS systems in this proposal are commercially mature systems that will allow unmanned technologies to be accessible by relatively new operators such as student researchers at the UW. The ability to use these types of systems quickly will allow students and research groups to rapidly deploy these types of systems and focus more on relevant science missions such as aerial surveys, animal monitoring, and precision agriculture. This type of accessibility to data and technology is crucial for many modern applications and will make the UW more competitive for future research and funding opportunities in the UAS arena.

Sincerely,

Christopher Lum, PhD, Dept. of Aeronautics & Astronautics

================================

I have just returned from the European Geophysical Union annual meeting, where there were no fewer than four special sessions in of talks and posters devoted to digital mapping in my discipline alone. Many of the presentations relied on photogrammetry with images acquired by UAV. It is clear that this is rapidly becoming a fundamental tool for data collection in fields ranging from civil engineering to archaeology, bedrock geology to geomorphology. Students will clearly benefit from access to UAVs, both to advance their research and to prepare for work in applied fields.

-Juliet Crider, Assistant Professor and Program Director of Applied Geosciences (MESSAGe), Dept. of Earth & Space Sciences

================================

I wish to give my strong endorsement to this proposal. UAVs are becoming increasingly important for science and in particular for overall site investigations. These systems can provide a wealth of information at a rate very much faster than the usual method of working the area.

The project that Mr Shean is involved with is a potential major forerunner for new research methods that will be undertaken by students at UW. Due to the newness of the proposed efforts there has been limited ability to support these efforts.

I think if this project is successful it will be used by other students that follow in his footsteps.

As such I fully endorse the students STF application.

Installation Timeline

The equipment will be ordered as soon as funding is received. The equipment will be available for student use as soon as it is received and cataloged, provided that student users are trained and competent with the equipment (see Access Restrictions).

Resources Provided by Department

Post-processing software (Agisoft PhotoScan Pro) is already installed on powerful workstations in the Quaternary Research Center GIS Lab, all purchased with past STF awards. This lab recently added new visualization and analysis tools designed to accelerate scientific research and foster collaboration. These resources include a 70” flat-screen monitor, multiple stereo monitors, and multiple high-end workstations built for 3D visualization. This lab is open between 9 AM to 5 PM Monday through Friday, and after-hours access can be arranged with lab manager and resident LiDAR expert, Harvey Greenberg.

The ESS department has several survey-grade GPS receivers, many purchased with past STF awards, that can be used for collecting ground control points needed for calibration. The GPS receivers are always available for student use. The GPS data can be processed using GPS Pathfinder Office, which is already installed on departmental computers.

There are multiple graduate students in the ESS department with experience flying and operating UAVs for mapping. They can instruct and provide the necessary information on how to safely use a UAV for mapping. One of the graduates, Tait Russell, is willing to lead a field trip for interested students and faculty. He will show them how to properly use a UAV for mapping.

Access Restrictions (if any)

The airborne mapping systems will be integrated with existing ESS STF equipment. Two ESS graduate students are in charge of maintaining, administering, and providing access to ESS STF equipment, and protocols are already established for checking out equipment. Access to airborne mapping systems would follow these protocols and would be permitted to students who have demonstrated that they can competently use the equipment in a safe and legal manner.

ESS students already have flight simulator software that is specifically designed to teach users how to fly UAVs. The flight simulation is very realistic and provides invaluable training for future pilots. This asset will increase the access of the UAV platforms to UW students by giving prospective pilots the necessary experience to safely begin flying real UAVs.

Equipment check-out will be available on a case-by-case basis, with requirements for basic knowledge of the technology and safety procedures. Complying with FAA regulations will be the responsibility of the user, although most small-scale mapping applications should fall under the FAA model aircraft regulations.

Student Endorsements

To Whom It May Concern:

I am writing this letter to express my strong support for this proposal. My research involves the use of high-resolution 3D imagery to study the mechanical properties of rocks and the earth. I rely on Structure-from-Motion technology to produce 3D models from digital images, and I often require the inclusion of images captured from perspectives that cannot be achieved from the ground. UAVs have been immensely helpful in accomplishing this task, and previous work using equipment similar to that in this proposal has produced strikingly accurate 3D models of geologic landforms and structures. Unfortunately, such UAV systems are not freely available for use at the UW, so I am forced to borrow equipment from collaborators at outside institutions. The borrowed UAV equipment is often not specifically designed for my application, reducing the image quality and complicating the image acquisition process. The devices requested in this proposal are well suited to a range of imaging needs, including large and small areas, and complex target geometries. Having these UAVs available for use through the department would directly benefit me in terms of both research quality and logistics.

Beyond my own research needs, it is clear that UAVs are rapidly becoming important in a wide range of applications. Indeed, new and novel uses are being developed at an unprecedented pace. Because of this, it is difficult to accurately gauge the impact the availability of such systems will have on university research, but even the established uses are impressive in terms of their scope and interdisciplinary nature: earth science, archaeology, atmospheric science, engineering, cinematography, photography and glaciology disciplines all stand to benefit from the funding of this proposal.

Sincerely,

Keith Hodson, Graduate Student, Dept. of Earth and Space Sciences

================================

I strongly believe that UAVs are the future of remote sensing. I have been building do-it-yourself UAV platforms and experimenting with this technology for the past year and half, but recent progress has slowed due to funding limitations and time constraints. Hardware development and testing requires rapidly-evolving expertise and a significant time commitment, which can be a roadblock for students focusing on scientific applications rather than engineering.

Last year, I led several field excursions with ESS undergrad and grad students to perform UAV surveys of glaciers and snowpack in the Cascades. While the results were very exciting, we did not have the necessary equipment to perform these surveys on our own, and had to establish external collaborations to gain access to the necessary technology.

The turnkey platforms in this proposal will enable students in UW ESS and beyond to leverage this promising technology without having to wield a soldering iron or focus on engineering details, accelerating scientific discovery.

-David Shean, PhD Candidate, Dept of Earth and Space Sciences

================================

As a research graduate student funding is often limited or meager with respect to topographic data acquisition resources and equipment; especially high-resolution and over large spatial scales. The coupling of modern tools and computer processing however is making state-of-the-art-science readily available at fractions of traditional costs. I study geomorphology and landscape evolution through mountain building and erosional surface processes, which has in recent years increasingly relied on high-resolution topographic data to answer process-based scientific questions. I find this proposal incredibly necessary and timely in order for UW graduate students to continue doing cutting edge research at relatively low-budget costs. I would use the proposed equipment as soon as this summer for my doctorate research.

—Jon Beyeler, Graduate Student, Dept. of Earth and Space Sciences

================================

I am a second year graduate student in the Department of Earth and Space Sciences. My research focuses on numerical models of glacier flow, and I will speak only to this proposal's relevance in this area even though I know it would be useful for many students in a number of other disciplines within earth science. In order to produce realistic models of glaciers, accurate elevation measurements of the surface and bed of the glacier are paramount. The proposed unmanned aircraft would greatly enhance our ability to produce highly accurate surface digital elevation models (DEMs) of local glaciers. The use of such craft is an exciting new area in glaciology, and one that is rapidly expanding. Having these resources available for students would both help keep the UW at the forefront of glaciological remote sensing techniques as well as provide an important opportunity for students like myself; the relative ease and speed with which elevation products can be made using these instruments makes them usable for small side projects tangential to students’ main areas of research. For example, though my research focuses on Antarctica, I would be interested in doing aerial surveys of glaciers on Mt. Rainer, which this proposal would make possible without additional funding. Finally, UW has a strong history of student projects on local glaciers, especially Blue Glacier on Mt Olympus. This proposal would fund a key new tool which would help continue UW’s tradition of local student projects glaciology.

—David Lilien, Graduate Student, Dept. of Earth and Space Sciences

================================

UAVs are rapidly proving themselves to be efficient and cost-effective tools for acquiring high resolution topographic data. I have been building and flying RC aircraft for the past half year, and I participated in UAV surveys of Easton Glacier on Mt Baker. The DIY approach that I have been taking has necessitated devoting large amounts of time to tinkering with aeronautical and electrical components. This time-consuming approach is barely sustainable for me, and it is not realistic for most Earth science graduate students. Purchasing ready-to-use commercial airborne mapping systems would be a boon to me and my peers for it would enable fast and easy acquisition of high-accuracy terrain data without having to worry about the details of aircraft construction and flight. I strongly endorse this proposal, and I am excited to see the scientific results that will follow.

-Perry Spector, PhD Candidate, Dept. of Earth and Space Sciences

================================

Collecting geospatial data quickly and economically is paramount for Earth science research. With UAVs, students and faculty at the UW will be able to collect geospatial data quickly and economically. The UAVs will also allow access to areas that were previously too dangerous or inaccessible. My previous research using UAVs to measure mass balance on the Easton Glacier of Mount Baker has shown the ability of UAVs to gather geospatial data with cm-resolution. With access to UAVs, other students at the UW will be able to gather geospatial data for their own research. I strongly endorse this proposal and hope to see innovative research using high-accuracy geospatial data.

-Tait Russell, MESSAGe Graduate Student, Dept. of Earth and Space Sciences

================================

UAVs would be crucial for research involving areas of interest aren't easily or safely accessible by foot. Examples would be unstable clifftops or fresh landslide headscarps. Although the use of a zoomed-in camera could achieve similar results, a UAV’s ability to get in close and examine the area of interest from different angles, while ensuring the safety of the operator, makes it an extremely valuable resource to have.

-Amanda Ong, MESSAGe Graduate Student, Dept. of Earth and Space Sciences

================================

I am a third-year geomorphology student in the Earth and Space Sciences Department and I strongly support this proposal. Many students in this department and across the UW campus would benefit from the use of UAVs for remote sensing and data collection in rugged field sites. UAVs are an invaluable tool and greatly expand the potential scope of student research by allowing data collection and access to places that might otherwise be too dangerous or time consuming. Additionally, having aerial views of field sites allows for a different perspective than on foot field work, and can illuminate patterns in the landscape otherwise not apparent. UAVs are state of the art technology, and will allow student researchers at the UW to participate in competitive and cutting-edge research. I strongly endorse this proposal.

Justification

Since submission of the original STF proposal in April 2015, UAV-based mapping technology has advanced significantly. Two of the UAV systems in the original proposal are now discontinued. This supplement requests approval to use allocated funds to purchase two newer UAV platforms, and to purchase additional supplies (batteries, spare parts) for the systems already in use.

Endurance multi-rotor UAV and 3DR Solo micro-UAS systems
==============================================
In the past year, students in ESS have established close connections with students and staff in the Autonomous Flight Systems Laboratory in the Aeronautics and Astronautics (AA) department. Rather than purchasing an expensive commercial multi-rotor system, we have recently partnered with undergraduate students in AA to identify the cost of a more capable, custom professional system to be built in-house at UW. The detailed parts list is provided in the supplement budget. The estimated costs are significantly less (~5-10%) than for a comparable commercial platform.

We see this path as a win-win, as it: 1) involves many more UW students (approximately 30 to 40 AA undergrads in the AFSL group) to advance STF goals, 2) provides resources and real-world training for engineering students to meet design requirements and build a system, and 3) promotes increased interdisciplinary collaboration between UW students across campus. This arrangement allows the engineers to focus on the engineering and the scientists to focus on the scientific research and data analysis. We anticipate increased collaboration and exchange in the coming year, as AA students build and test the system. The AA students have extensive flight experience and experience navigating the constantly evolving regulatory framework. We anticipate that AA students will partner with less-experienced students from ESS (and other UW depts.) to provide training or serve as pilot-in-command during flights. This will also provide opportunities for AA students to accompany ESS students to field sites to perform surveys using the new system. While in the field, ESS students can teach AA students about the science and motivation for the UAV surveys.

This professional-grade UAV mapping system will provide autonomous survey capabilities. It replaces the discontinued 3DR Aero-M from the original proposal. The system will allow for collection of high-resolution image data for large areas, filling a niche between the long-range fixed-wing eBee system and smaller, short-range Phantom 3 quad-copters in the original proposal. Inclusion of a cm-accuracy GPS navigation system will offer significantly-improved survey results, with reduced effort during data acquisition and processing.

The 3DR Solo quad copter is a new, inexpensive UAV mapping system that replaces the discontinued 3DR X8-M in the original proposal. 3DR is a leader in user-oriented UAV mapping systems, and the modular design of the Solo will allow us to upgrade the UAV as new sensors become available. The Solo is capable of autonomous navigation to fly systematic survey grids during data collection. This capability complements the capabilities of the existing small Phantom quadcopters, which are very easy to operate, but require manual control at all times. We will work with AA students to integrate custom sensor packages with the Solo, to provide UW students with a lightweight, autonomous survey platform for small-scale mapping applications. At under 4.4 lb, this platform is classified as a “micro-UAS” and will be subjected to less-restrictive regulations than the larger, heavier multi-rotor system. For this reason, we believe it will be a valuable part of the proposed STF UAV fleet to accommodate the needs of all UW students, regardless of experience.

These UAV systems replace approved items from the original proposal, so no additional costs are associated with this purchase. This supplement only requests formal approval to acquire updated, state of the art UAV systems instead of the discontinued models requested in the original proposal.

Essential Accessories for DJI Phantom UAVs
===================================
The DJI Phantom 3 UAVs have already seen use producing maps and 3D models for research projects in ESS. During this time, it has become clear that the utility and longevity of these UAVs could be extended with the addition of the listed accessories.

The Phantom UAVs require connection to a mobile device, such as a phone or tablet, to display live image feeds from the UAV camera. Mobile devices were not requested in the original proposal, forcing users to source their own. To ensure accessibility to people who cannot source a compatible device, we are requesting funding for two simple iPad 4 Mini tablets to be dedicated to the two Phantom UAVs. In addition to providing a complete hardware package to future users, having these dedicated tablets will make it easier to maintain required software and firmware.

Flight time has proven to be a limiting factor, with practical battery life on the order of 10 to 15 minutes. The combined flight time for our four-battery supply is less than an hour, and this time constraint has made it difficult to complete larger mapping projects. Additionally, these four batteries are shared between our two Phantom UAVs, which is problematic when both devices are being used. The four additional batteries requested here will increase our supply to 8 batteries between the two UAVs, providing each with the capability for up to an hour of flight time.

Additional rotors are requested to help prolong the functionality of the Phantoms UAVs. In minor accidents it is common to damage the rotors, with the rest of the UAV going relatively unscathed. One set of replacement rotors was included with the original purchase, but the additional sets will help ensure that a small crash will not ground the UAV until replacement rotors can be acquired. As new versions of the Phantom are released (the newer Phantom 4 is already available), replacement parts for our system will become more difficult to locate. Because these parts are inexpensive, it makes sense to acquire a supply now.

The requested items will resolve some logistical issues that have surfaced during our initial use of the Phantom 3 UAVs. The batteries, tablet computers, and spare rotors will address some shortcomings of our initial hardware request, ensuring ample flight time, access to complete hardware needs, and that basic spare parts will be available in the future. Cost savings during purchasing and M&E tax exemption have freed up sufficient funds remaining in the budget to cover these costs. We only request approval to purchase these additional items, not for additional funding.

https://www.amazon.com/dp/B00MHPAES4/ref=twister_B00Q7GLLWC?_encoding=UTF8&psc=1

Justification

In the original proposal submitted to the STF, we requested a compact, high-resolution digital camera for use with the mapping unmanned aerial vehicles (UAVs). The requested camera, a Sony NEX-5N, is no longer in production and cannot be easily procured (http://www.sony.com/electronics/cameras). We are requesting authorization to acquire the updated version of this camera: the Sony a5100. These two cameras are almost identical in most respects, although the newer model does have a higher resolution detector (24 vs. 16.1 MP), more memory, and costs ~$200 more than the amount awarded in the original budget. The originally requested NEX-5N can still be found online, but the price has skyrocketed to over $500, more than the cost of the newer a5100 model. Clearly, it doesn’t make sense to buy the older model for more money. The additional cost of the replacement camera is easily offset by savings made with the last supplemental, so there will be no need to adjust the original awarded amount.

“Your Phantom 3 fits into your life and makes flying remarkably intuitive and easy. From takeoff to landing, it's completely under your control, responding to your commands while automatically handling the most complex aspects of safe, stable flight.” – DJI

After considering other low-cost UAVs, the DJI Phantom 3 Professional was found to be the best for beginners. The Phantom is designed to be very easy and safe. It is gps-assisted when flying by remote control, which prevents the UAV from drifting in the winds. Also, it has a built-in “return-to-home” function that returns the UAV to its take-off position in the event that the remote control signal is lost or the battery falls to a critically low level. It comes pre-programmed with all FAA type A and B “no-fly-zones” in the country, which restricts the UAV usage in FAA “no-fly-zones”.

Justification

Since submission of the original STF proposal in April 2015, UAV-based mapping technology has advanced significantly. Two of the UAV systems in the original proposal are now discontinued. This supplement requests approval to use allocated funds to purchase two newer UAV platforms, and to purchase additional supplies (batteries, spare parts) for the systems already in use.

Endurance multi-rotor UAV and 3DR Solo micro-UAS systems
==============================================
In the past year, students in ESS have established close connections with students and staff in the Autonomous Flight Systems Laboratory in the Aeronautics and Astronautics (AA) department. Rather than purchasing an expensive commercial multi-rotor system, we have recently partnered with undergraduate students in AA to identify the cost of a more capable, custom professional system to be built in-house at UW. The detailed parts list is provided in the supplement budget. The estimated costs are significantly less (~5-10%) than for a comparable commercial platform.

We see this path as a win-win, as it: 1) involves many more UW students (approximately 30 to 40 AA undergrads in the AFSL group) to advance STF goals, 2) provides resources and real-world training for engineering students to meet design requirements and build a system, and 3) promotes increased interdisciplinary collaboration between UW students across campus. This arrangement allows the engineers to focus on the engineering and the scientists to focus on the scientific research and data analysis. We anticipate increased collaboration and exchange in the coming year, as AA students build and test the system. The AA students have extensive flight experience and experience navigating the constantly evolving regulatory framework. We anticipate that AA students will partner with less-experienced students from ESS (and other UW depts.) to provide training or serve as pilot-in-command during flights. This will also provide opportunities for AA students to accompany ESS students to field sites to perform surveys using the new system. While in the field, ESS students can teach AA students about the science and motivation for the UAV surveys.

This professional-grade UAV mapping system will provide autonomous survey capabilities. It replaces the discontinued 3DR Aero-M from the original proposal. The system will allow for collection of high-resolution image data for large areas, filling a niche between the long-range fixed-wing eBee system and smaller, short-range Phantom 3 quad-copters in the original proposal. Inclusion of a cm-accuracy GPS navigation system will offer significantly-improved survey results, with reduced effort during data acquisition and processing.

The 3DR Solo quad copter is a new, inexpensive UAV mapping system that replaces the discontinued 3DR X8-M in the original proposal. 3DR is a leader in user-oriented UAV mapping systems, and the modular design of the Solo will allow us to upgrade the UAV as new sensors become available. The Solo is capable of autonomous navigation to fly systematic survey grids during data collection. This capability complements the capabilities of the existing small Phantom quadcopters, which are very easy to operate, but require manual control at all times. We will work with AA students to integrate custom sensor packages with the Solo, to provide UW students with a lightweight, autonomous survey platform for small-scale mapping applications. At under 4.4 lb, this platform is classified as a “micro-UAS” and will be subjected to less-restrictive regulations than the larger, heavier multi-rotor system. For this reason, we believe it will be a valuable part of the proposed STF UAV fleet to accommodate the needs of all UW students, regardless of experience.

These UAV systems replace approved items from the original proposal, so no additional costs are associated with this purchase. This supplement only requests formal approval to acquire updated, state of the art UAV systems instead of the discontinued models requested in the original proposal.

Essential Accessories for DJI Phantom UAVs
===================================
The DJI Phantom 3 UAVs have already seen use producing maps and 3D models for research projects in ESS. During this time, it has become clear that the utility and longevity of these UAVs could be extended with the addition of the listed accessories.

The Phantom UAVs require connection to a mobile device, such as a phone or tablet, to display live image feeds from the UAV camera. Mobile devices were not requested in the original proposal, forcing users to source their own. To ensure accessibility to people who cannot source a compatible device, we are requesting funding for two simple iPad 4 Mini tablets to be dedicated to the two Phantom UAVs. In addition to providing a complete hardware package to future users, having these dedicated tablets will make it easier to maintain required software and firmware.

Flight time has proven to be a limiting factor, with practical battery life on the order of 10 to 15 minutes. The combined flight time for our four-battery supply is less than an hour, and this time constraint has made it difficult to complete larger mapping projects. Additionally, these four batteries are shared between our two Phantom UAVs, which is problematic when both devices are being used. The four additional batteries requested here will increase our supply to 8 batteries between the two UAVs, providing each with the capability for up to an hour of flight time.

Additional rotors are requested to help prolong the functionality of the Phantoms UAVs. In minor accidents it is common to damage the rotors, with the rest of the UAV going relatively unscathed. One set of replacement rotors was included with the original purchase, but the additional sets will help ensure that a small crash will not ground the UAV until replacement rotors can be acquired. As new versions of the Phantom are released (the newer Phantom 4 is already available), replacement parts for our system will become more difficult to locate. Because these parts are inexpensive, it makes sense to acquire a supply now.

The requested items will resolve some logistical issues that have surfaced during our initial use of the Phantom 3 UAVs. The batteries, tablet computers, and spare rotors will address some shortcomings of our initial hardware request, ensuring ample flight time, access to complete hardware needs, and that basic spare parts will be available in the future. Cost savings during purchasing and M&E tax exemption have freed up sufficient funds remaining in the budget to cover these costs. We only request approval to purchase these additional items, not for additional funding.

Supplemental 2 - Updated Camera

$0.00 1 $0.00
Description

Updated camera body (Replaces Sony NEX-5N in item 5):

Sony a5100 Mirrorless Digital Camera - Body Only ($448.00 + tax)
https://www.amazon.com/dp/B00MHPAES4/ref=twister_B00Q7GLLWC?_encoding=UTF8&psc=1

Justification

In the original proposal submitted to the STF, we requested a compact, high-resolution digital camera for use with the mapping unmanned aerial vehicles (UAVs). The requested camera, a Sony NEX-5N, is no longer in production and cannot be easily procured (http://www.sony.com/electronics/cameras). We are requesting authorization to acquire the updated version of this camera: the Sony a5100. These two cameras are almost identical in most respects, although the newer model does have a higher resolution detector (24 vs. 16.1 MP), more memory, and costs ~$200 more than the amount awarded in the original budget. The originally requested NEX-5N can still be found online, but the price has skyrocketed to over $500, more than the cost of the newer a5100 model. Clearly, it doesn’t make sense to buy the older model for more money. The additional cost of the replacement camera is easily offset by savings made with the last supplemental, so there will be no need to adjust the original awarded amount.

Overall total funded: $44,079.89
