Drones: Why the big push now?
• Increased reliability, portability
• Decreased cost
• Sensors are getting smaller, software more
accessible
• FAA Part 107
• Easing of DOI rules and procurement options
Hydrogeophysics & UAS 3
Regulatory Context: FAA
• 2016: FAA Part 107
– Commercial use w/o case-by-
case FAA review
– Remote Pilot exam & license
– Airspace restrictions
– Maximum altitude 400’ AGL
– Visual line of sight
– Daylight operations
– Can’t fly over other people
4
Regulatory Context: WhiteHouse
• Federal civil sUAS use
• Safeguard
– Privacy,
– Civil Rights, and
– Civil Liberties
• Platform, not resolution
– Same data collected by
sUAS vs helicopter/plane
subject to different handling

UAS Value to
USGS Hydrogeologic Field Studies• Collect Data in difficult/impossible to access areas
• Improved safety
– Data comparable to that collected by foot, boat, or traditional aircraft
• Reduced costs and improved operational efficiencies
– Quickly assess site conditions, inform equipment placement, or
location of sampling and monitoring activities
• High-resolution geo-referenced imagery, 3D elevation models
(DEM), GW/SW Interaction, Biologic Surveys, Hazards
– Inform, constrain, and improve site conceptual, geophysical,
geochemical, biological, and numerical models.
• Automated georeferenced flights aid repeated surveys
– Multiple sensors along the same transects
– Monitoring changing conditions over time
