@severin @organicmaps Same here, but for some reason those contours seem to be offset of data: not only the path in the second image seems to weirdly take a steep turn, the torrente also seems to not quite go through the base of the valley. If it were just the torrente I would not say anything.
@mdione @severin elevation data is tricky. And usually has low precision. And OpenStreetMap.org data may also be imprecise. The situation may improve when more open elevation datasets become available.
