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

Final Classification

Field SCAT vs. Remote Sensing

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
