Re: [geolocation-sensor] Barometer altitude (if the device has barometer) (#43)

Hello, a few use cases for the barometer:

You should know that the returned GPS altitude is never very good, and above all fluctuating. GPS records with GPS altitudes overestimate the height differences by around 10 to 30%. Barometric altitude does not encounter these problems and provides much more reliable results.

All the major services which analyze the GPS files generally recalculate the altitudes (with a DEM) when they come from the GPS.

Use case :
Jogging / trail / road bike / mountain bike, to know with precision the height difference made during an outing, and here we are not in the niche market!
