Ethan Jacobs, unmanned aerial system engineer, launches a UAS during a field test Sept. 4 at Joint Base San Antonio-Camp Bullis. The UAS was equipped with Light Detection and Ranging, multi-spectral sensors and machine-learning algorithms to map, survey and inventory habitat for the golden-cheeked warbler. The field test will help the Air Force determine if UAS technology can characterize habitat better, faster and cheaper than current methods.
