Function Documentation

bool dem_load (  const char *  filename,
const char *  demname = 0
) 
 

Tcl syntax:
dem_load "filename" "demname"
Description:
loads DEM named 'demname' from surfit datafile. If no demname specified, then loads the first one.
Parameters:
filename surfit datafile
demname name of DEM (optional)

bool dem_load_dtm (  const char *  hdr_filename,
const char *  name,
const char *  bin_filename = 0
) 
 

Tcl syntax:
dem_load_dmt "hdr_filename" "demname" "bin_filename"
Description:
loads DEM from DTM files (hdr + bin)
Examples:
canyon_prepare.tcl.

bool dem_load_globe (  const char *  filename,
const char *  demname = 0
