Any idea how the quality compares with just using Open Street Map elevation data?

  OpenStreetMap does not have much of its own elevation data. (There is a way to tag elevation, but it is rather seldom done). Any project that shows you OSM data and elevation is probably pulling in third-party elevation data such as that from the Shuttle Radar Topography Mission (SRTM)[1].

    I was pleasantly surprised to learn that Airbus sells a very nice Digital Elevation Model. It seems to be quite a lot better than the shuttle data everyone was using for a while. http://www.intelligence-airbusds.com/worlddem/ http://www.intelligence-airbusds.com/worlddem/

    The elevation data in OSM is mostly just an elevation data on peaks and such, not actually DEM stuff
