I have a global glc-2000 raster map. I would like to clip it to study specific area. I used boundries of continents shapefile as mask. Both of them have same projection. Since I am beginner I have followed steps of this tutorial using QGIS 3.6: http://www.qgistutorials.com/en/docs/raster_mosaicing_and_clipping.html
I hoped that I get Europe output raster layer but the result was a black hole. What went wrong?
