Sensors more accurately

Wetlands are critical to the health of bodies of water like the Chesapeake Bay. But many wetlands are forested, and it can be hard to see the wetlands on aerial photography because the view is blocked by the trees. Also, maps drawn from aerial photographs are subjective, causing more loss of accuracy.
With the combined data from the two types of remote sensing devices, the scientists can see whether water flows without filtration into the Bay, or whether it flows first through a forested wetland that might filter out possible pollutants.
