Mapping Spills Better and Faster
Traditional Approach: Visual observations from helicopter or aircraft converted to drawing on a map using GPS.
Our Approach: Easily-deployable computerized system utilizing multiple imaging channels in the visible, near-IR & thermal-IR
Advantages over visual methods:
1) System is objective – does not rely on opinion and experience of operator
2) Survey map is in digital GIS format – allows accurate location determinations, direct computation of oil spill area and volume, etc.
3) Survey provides much greater detail

Analysis maps were utilized for multiple applications including:
Source area oil distribution forresponse resource management & trajectory modeling
Location of recoverable oil targets
Location/extent of beached and marsh-entrained oil
Effectiveness of dispersants
Locating recoverable oil targets
Dispersant Monitoring

Lessons Learned: Advantages:•Aerial image-derived oil analyses are useful for multiple response applications
•Especially useful for supporting SCAT field activities in hard-to-reach marsh areas
•Potential new aerial dispersant application monitoring method
Limitations: •Daily spatial coverage is limited for very large spills
• Technology is still novel – not yet fully incorporated in specific response protocols
