Submitted as ticket# 3947 but I had to link the sample data because of size. -marius

You can raise a ticket at http://trac.osgeo.org/gdal/newticket and attach the data.

Both cutline shapefile and raster are using the same projection. On the sample raster dataset (pixel=28.5m) the shift is about 5m to the east and 3.5m to the north. Pixel values remain the same (so resampling doesn't take place, as expected). I should add that not adding -crop_to_cutline results in no shift. Commands I ran: (1) gdalwarp -cutline mask.shp -crop_to_cutline sample.tif cropped.tif result is shifted (2) gdalwarp -cutline mask.shp sample.tif out.tif result is not shifted A workaround would be using gdal_rasterize on after option (2) above. -marius _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev -- Best regards, Chaitanya kumar CH. /tʃaɪθənjə/ /kʊmɑr/ +91-9494447584 17.2416N 80.1426E
