I meant open street maps. I'm not trying to be a wise-ass, just genuinely interested in the statement "I don't know how it is possible to enjoy cycling without paper maps."
As for contours, you can find them on opencyclemap and opentopomap (with hillshading).
I love building routes and couldn't do it without the opencyclemap detail combined with google streetview and heatmap. (All possible in RWGPS).
