what about using gdal? see http://www.gdal.org/gdalbuildvrt.html gdalbuildvrt: Builds a VRT from a list of datasets. you can read the orthoimages by gdal without unzip, see: http://trac.osgeo.org/gdal/wiki/UserDocs/ReadInZip then you can use gdal_translate (http://www.gdal.org/gdal_translate.html) to translate the raster VRT into _one_ (big) orthoimage. ----- best regards Helmut -- View this message in context: http://osgeo-org.1560.x6.nabble.com/using-USGS-chunked-TDDS-orthoimagery-tp5187740p5187925.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
