In Czechia and Slovakia we have mapy.cz which gives you more detailed map for walking/hiking, including contour lines. See [^1] for example.
The coloured trails you can see at more detailed zoom levels, are part of the hiking trail system. The outdoor signage even has a national technical norm [^2] (in Slovak, but has some terminology translated int to English and German).
