gdalwarp cutline along with shapefile

Question

I am trying to clip my Raster file according to a shape file geometry. I am using the following code

gdalwarp -cutline INPUT.shp INPUT.tif OUTPUT.tif

But it is resulting a black color outside the shape file geometry extent. I am giving the example here. In the first Image that I want to clip. The second image is the resultant raster but I want the 3rd Raster where the outside of the geometry will be null.

1st Image: INPUT Raster

2nd Image: OUTPUT Raster

3rd Image: I want to get output like this

Answer 1

Try to specify the nodata-value from your input raster and set it for the output as well. Furthermore add the option -crop_to_cutline to make exact crops. More about the options here.

gdalwarp -srcnodata <in> -dstnodata <out> -crop_to_cutline -cutline INPUT.shp INPUT.tif OUTPUT.tif

Answer 2

You can use raster clip option in QGIS which runs gdalwarp in the background and configures the right options for you.
