Description (last modified by )
When running gdalwarp using -cutline and -crop_to_cutline options, the resulting raster is slightly shifted. 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
