scripting to make geo tiffs

[Anthony G Burns]

R Joe Brandon

I modified a script developed by Jill Schuler to create a true geotif file.
 The libtiff and libgeotiffs libraries must be available as the script is
using these libraries to create the geotif by placing geo coordinates tags
in the tiff file.  The script works on grass files in the UTM projection,
but could easily be modified to work in other projections (portions of the
tags are hard coded in the script).  You can loop throught a list of file
names to create the geotiffs.  The syntacs would be  rast.to.geo  <input
raster file name >   <output geotif file name>    The scripts appends a tif
extension to the output name.

The scripts requires a good bit of disk space as it creates a uncompressed
tiff as an intermediate step and they can be quite large.

If you think this can help you, let me know.
