This is a KML network link that displays the map tiles from http://opentopomap.org/ as a map overlay in Google Earth. OpenTopoMap is an university-sponsored project that tries to emulate the graphical style of official German topographic maps (which were hand-drawn until recently), with an emphasis on readability and contrast. Currently, tiles are only available for Europe, but that might change.
For some information on how it works, please see the main page and the FAQ.
To get started, simply download all 6 European Maps map overlays on this site.(please log in first, see here why) and open it in Google Earth. Or checkout
