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, orthographic, Mercator and other projection maps.
  Mac App Store version SimpleDEMViewerAS is available. Some restrictions are added because of Mac App Store technical requirement.

DEMs supported

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