Hi all, I have a georeferenced raster and want to crop it using shapefile as mask layer. I use next command:
gdalwarp -q -cutline myshape.shp -crop_to_cutline -of GTiff input.tif output.tif All fine except one thing: the output raster has another pixel size than input. For example, input raster has pixel size 0.00833333,-0.00833333, and output has 0.00833129,-0.00833387. I suspect this is related to rounding and 0.5 pixel offset (top left corner vs. pixel center). When mask is rectangle, I can use gdal_traslate to clip, but often I need to crop raster by non-rectangular mask. Is it possible to do this without raster grid resampling? Keeping pixel size is very important for further analysis.
