My name is Randall Cohen, and I have experience piloting various UAV platforms to capture aerial data from urban and rural sites around the world. I have flown for, and assisted such companies as AECOM, Apple, Bechtel, Gallo Wines, and Komatsu on some of the largest and complex construction and agricultural projects under development. Field duties have included identification of parcel boundaries and property borders to build georeferenced 2D orthomosaic base maps, 3D point clouds, multispectral NDVI, thermal, and topographic maps tailored to output needs. Collections have included construction progress and laydown scheduling, stockpile volumetrics, open-pit measurements, transmission line and solar array inspections, historic and cultural sites, wetland habitat monitoring, wildland-urban interface observations and agricultural health monitoring. I have extensive experience building maps in the field using Pix4D and Agisoft Photoscan photogrammetry softwares enabling results to be rendered on-the-fly following flight demonstrations, sensor testing, and mission planning adjustments. Additionally, I have experience working with foreign governments in natural disaster zones acquiring clearance for flights and collection of data over culturally sensitive areas.

Other technical duties included sUAS pilot training for AECOM and Bechtel domestically, as well as Komatsu, UNESCO, and the Nepal Department of Archeology abroad. I have experience as a contributing technical author for instructional flight training, and maintenance manuals for custom built fixed wing and multi-rotors. Additionally, I aided in design and testing of autopilot applications to control flight characteristics of both the DJI and Skycatch drones to provide tablet based mission planning. During the evolution of the Skycatch multirotor UAS I Investigated hardware issues as they arose, and tested to evaluate proposed solutions to ensure high quality across the entire Skycatch product line by profiling and providing performance analysis of sensors, components, and payloads.
