I found a layer on a web map server that shows elevation data (no shaded
relief as I think). Is it possible to convert the color information that
is in the image back to elevations? Here a link to one image:
I suppose r.mapcalc would be the tool to use, but it seems not possible
without the right color map. Any suggestions?
PS: I'm sorry for being a bit off topic, as this is not mainly grass
