Dear Rasterio developers and useers,

I' masking geotiff files with geojson polygons:

rio mask --overwrite --crop in.tif out.tif --geojson-mask mask.geojson 

Unfortunately after doing so black artificats showing up around the cropped area.



Is there a way to avoid this artifacts?


It looks like your input.tif may have lossy compression applied, and the output will have the same compression by default. You might try

rio mask --overwrite --crop in.tif out.tif --geojson-mask mask.geojson --co COMPRESS=NONE
