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.”

Mapping/Flight Operations Tips

• Slow Shutter Speed

• Unstable Platform

• Camera Resolution

• Things in Motion

– Trees (Wind), Water etc.

• Little or no Texture

– Sand, Snow

• Repeating Texture

– Forest, Farm Fields

• 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.
