I did a track on my ebike, just around home. Track line said a 191 mts low. Impossible. Home is the lowest place on track at 350. I guess it lost gps signal while in the wood and something went wrong. And a 2000 mts up/down overextimation.![alt text](image url)
Hello @stranger401, we are aware of these locations around the world. However, this problem should be addressed to Open Street Map, since we use their maps and have no control over them. Once the map is corrected on OSM, it takes some time for the changes to be reflected in the application as well.
Base map layers are generally pre-generated by a tile server, thus I don't think their own measure units may be changed. Measure units settings made via Windy UI are rather related to data map overlays, not to base map layers.
