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

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
