This driver is built-in by default
GDAL includes support for reading USGS SDTS formatted DEMs. USGS DEMs are always returned with a data type of signed sixteen bit integer, or 32bit float. Projection and georeferencing information is also returned.
SDTS datasets consist of a number of files. Each DEM should have one file with a name like XXXCATD.DDF. This should be selected to open the dataset.
The elevation units of DEMs may be feet or meters. The GetType() method on a band will attempt to return if the units are Feet (“ft”) or Meters (“m”).
