gdalchop is a tool responsible for cropping height data files into SimGear buckets (or tiles).


Most height data is published in fairly large data files that cover 1 square degree.  For SRTM-1 data, there are 3601 x 3601 data points per file.  For SRTM-3 data, there are 1201 x 1201 data points per file.  SRTM datafiles are named by their southwestern most point.
