The vertical accuracy of the ASTER GDEM was determined for CONUS by comparing the ASTER GDEM tiles that comprise the CONUS area with corresponding 1-arc-second data from the USGS National Elevation Dataset (NED). Vertical accuracy of NED data is approximately m RMSE. The ASTER GDEM version 2 was validated against the 10 m-mesh DEM produced by the Geographical Survey Institute (GSI) of Japan. The tiles selected for validation study were N35E, N35E, N36E and N36E (Fig. 1). They were located in central Japan which covers sea level to very steep over m high peaks. Shuttle Radar Topograp.
