SYNOPSIS

ossim-chipper [,option/]... [,input-option/]... ,<input-file(s)> <output-file>/

DESCRIPTION

Note at least one input is required either from one of the input options, e.g. --input-dem <my-dem.hgt> or adding to command line in front of the output file in which case the code will try to ascertain what type of input it is.

Available traces: -T "ossimChipperUtil:debug" - General debug trace to standard out. -T "ossimChipperUtil:log" - Writes a log file to output-file.log. -T "ossimChipperUtil:options" - Writes the options to output-file-options.kwl.

Description: ossim-chipper Utility application for generating elevation products from dem data.
