Well, I didn't quite. The location API returns HAE. For a program to show that value to a human as "elevation" is buggy. So in addition to what I said, you have to add "your software is buggy". File a bug with that app! On Android: install GPSTest (available in F-Droid). It will show two heights. One is mislabeled "Alt", when it should say HAE*, and the other is "Alt (MSL)" which is the WGS84 sea level type height. * I have discussed with the author, but the notion is that people will be baffled by HAE. However, I think that's better than misinterpreting it as a gravity-based height install OsmAnd. In addition to maps, get the "World Altitude Correction" map. This is really the WGS84 gravity model, and when it is loaded OsmAnd will convert HAE from Android to height above the WGS84 gravity surface _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
