Sorry, I do not understand...You mean to write the spatialRef to a txt file and then doing something like: $ ogr2ogr -a_srs spatialRef.txt dst_shape.shp src_shape.shp Is this what you mean? Where inside the txt file there is: GEOGCS["GCS_WGS_1984", DATUM["WGS_1984", SPHEROID["WGS_19

Do you know how stretch an image using GDAL? Is this possible? If not, what method can I use? I need to stretch to Byte but in an equalized mode! I know that there is the scale tool in gdal but I don't know how make the stretch! Thx -- View this message in context: http://osgeo-org.1803224.n2.na
