I found your tutorial very helpful and tried to use the code what you have shown to mask a raster file,but it does nothing. code am trying gdalwarp -co COMPRESS=DEFLATE -co TILED=YES -of GTiff -r lanczos -cutline shapefile.shp sourcefile.tif destfile.tif and am trying this in osgeo4W command prompt, and the whole code is in one single line anykind of help would be much appriciated, please help me looking forward to hear from you Thanks Heaps Cheers Hi Tim,
