A. The table below shows the differences. Basically, the advantage of getting the SRTM over the NED is that SRTM is more current. This would especially be important over mining and quarry areas. The elevation from the NED is a bare ground reading where as SRTM is canopy based. To read more about the SRTM go to the home page at http://srtm.usgs.
