EXPORTING A FLOATING POINT GRASS RASTER TO PHOTOSHOP

The GRASS image export module r.out.tiff segmentation faults (crashes) when exporting floating point raster data. Since reprojection with cubic interpolation, and our shaded relief script both create floating point GRASS raster files, this is an obstacle to exporting to Photoshop. It is not possible to export floating point as binary (the other standard method of getting data into Photoshop) since Photoshop only imports integer-binary data. Our work-around is to use the PPM export format. Photoshop does not understand PPM, but The GIMP, a free Unix image editing program, does. Once the file has been opened in The GIMP, then you can export it as a TIFF file.
