This question already has an answer here:
I have a map built with a shapefile for country contours and a raster from .hgt files with elevation representation. How can I only select the area corresponding to the country?
I found some thing for matlab extract only the elevation of a country but not in QGIS. I'm thinking of using a polygon, but I am not familiar with how to do so. Or in a subtraction of the outside, but how to determine that? On the image, the red lines show the parts I want to eliminate.
