Maps Alpine Map

Hey, could someone please create a map like this. Grey areas indicate high mountains, white areas flat land and the black line indicates the location of a river. The map is based on the area near the city of Sargans in the Swiss alps.

 

The actual area topography please The center coordinate concerning GM is: 47.044153, 9.471396. Maps in CXL cover an area of 10x10 km if I am not mistaken... than the map would look like this:



Thank you in advance
