SimleDEMViewer

About

SimpleDEMViewer browses DEM ( Digital Elevation Model ) data as a relief map. It displays colored map with shading. Since no data is included in this package, user should prepare DEM data separately.
SimpleDEMViewer draws bird's-eye view, stereographs, panorama view, grayscale map, orthographical, Mercator and other projection maps.

DEMs supported

GTOPO30, HYDRO1K, SRTM, SRTM DTED, SRTM30plus, ETOPO1, ETOPO2, ETOPO5, GLOBE, GDEM, GeoTiff, netCDF, some BIL forms, USGS Ascii, USGS SDTS, ArcInfo Ascii, DEMs from GSI of Japan.
