Using USGS and SRTM Data
- Use USGS 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.
The above contour map was generated from a grid file in BIL format,
downloaded from the USGS The National Map Seamless Server
