Options for "Update elevation" [DE] Optionen für "aktualisiere Höhe..."
The actual function is the following:
(1) the value displayed during track recording shows elevation gain calculated from raw GPS data received from the phone GPS unit, including its deviations. (2) When saving a recorded track, Locus re-calculates the whole track elevation gain and optimizes it with all parameters stated in the "Altitude manager" - SRTM data, pressure sensor, automatic offset, filters etc. (3) If you select to "update elevation" of the whole track, the elevation gain is calculated only from offline elevation data (SRTM) that are based on a 3D model of the Earth.
So it is not possible, to update elevation statistics back to raw data (1) or Altitude Manager optimization (2).
THE IDEA IS:
The function "update elevation" should have 3 options:
1. Calculation from SRTM (what is the only one now)
2. Restore raw GPS (what you see during tracking)
3. Re-calculation based on Altitude Manager setting
To be able to do this, Locus must save the needed data with every track point: raw GPS, pressure and may be some more...
