--d: used to specify the directory path to the location of existing
- SDF files (presumably created at an earlier date through the
- usgs2sdf or postdownload utility) that are to be used to replace
- outliers found in the SRTM data file. The -d option overrides
- the default path specified in your $HOME/.splat_path file.
-
--n: used to specify the elevation (in meters) below which SRTM data
- is replaced. Below this limit, SRTM elevation data is either
- replaced using existing SDF equivalent files, or averaged among
- adjacent elevation data points. The default threshold for the
- replacement limit is sea-level (0 meters). Unless elevations
- below sea-level are known to exist for the region being
- processed by the srtm2sdf utility, the -n option need not be
- specified.
