Strava:
Now, we have a new elevation look-up service powered by data from the Strava community.
Each activity that is uploaded from a device with a barometric altimeter is used to build the Strava elevation basemap. Using this basemap to look up your elevation will provide a better elevation service because barometric altimeters are known to be more accurate than the public database. Not only will elevation be more accurate on Strava, but using the basemap will result in more consistent metrics between devices, both with or without a barometric altimeter.
If there is no basemap data available for all or part of your activity, we will use the former method with the public database. If you opt to correct your elevation after recording with a barometric altimeter, we will also use the basemap.

"verzichten" war wohl zu reisserisch. Wo nur GPS vorhanden ist, werden wohl wie auch bisher die GPS Höhendaten verwendet werden - über kurz oder lang wird das aber wohl auslaufen, oder die GPS Karten werden mit den barometrischen Werten aktualisiert/validiert/parametriert
