What We Want
• Remove Some Risk
• Perform Our Tasks Efficiently
• Provide Added Value
Current Issues
• Regulations
– Non-participants
– 91.119
– BLOVS
• Platform Limitations
– Sensors
• Avoidance and GPS
• Power and Quality
– Weather
• Human Piloting
What We Can Get
• High Resolution Imagery Typically Difficult to Acquire
• 3D Modeling
• Thermal Loading
– Concrete Delamination

UAS for Mapping
“One of drones’ many
boons is to
democratize the
process of
mapmaking. They are
far cheaper than the
mapmaking
technologies they
replace.”

Desktop/Cloud
• Lighting Changes
– Clouds or Time of Day
• Not Enough Overlap
• Different Software Processing Packages
• Aerial Imagery
– Low altitude causes greater perspective change causing
more post processing to “make it look right” for things that
protrude from the ground.UAS
