Detailed Description

Illustration of the effects of a vegetation canopy on SRTM data and the derived SRTM NED difference grid for an area in southern Michigan. The large difference in the middle of the profile, ranging up to 15 meters, is due solely to the presence of trees. The profile length is about 3.8 kilometers.
