My goal is to display the contour lines of the relief in Google Earth.
So, I would like to export from OpenStreetMap the contour lines of the relief of a region.
My goal is to download the data as a kml, to load them into Google Map.
I was hoping a query like that to work in OverPass:
node ["contour"="elevation"] (42,1,43,1.5); out body;
It does not. I could not find a more appropriate tag. According to OSM wiki, it does not exist.
Is there any other way?
