Using USGS and SRTM Data

Use USGS Digital Elevation Model (DEM), National Elevation Dataset (NED) and NASA Shuttle Radar Topographic Mission (SRTM) data with any Surfer command that uses grid files.

  • Directly use the files in native format without modification or conversion.
  • Display information about the files, such as X, Y and Z extents or grid statistics.
  • Create contour, vector, shaded relief, image, 3D surface, and 3D wireframe maps from the files.
