Audio Coach reports Elevation. Does it use settings in Altitude Manager?
Question: When reporting Track Elevation, does the Audio Coach use the settings in Altitude Manager?
Problem: The Audio Coach (V3.22) can now periodically report Track Elevation. However, I believe the reported elevation may be sourced directly from the GPS and does not use the settings in Altitude Manager.
Description: I've used several navigation apps on my phone and none have calculated an accurate value for Total Ascent (Total Elevation Gain). The final result is usually an inflated value that is far higher than the realistic value recorded by a barometric altimeter.
The solution I've used in the past is to import the track into Runalyze or Garmin Connect, which ignore the track's elevation data, and calculate the total ascent using a Digital Elevation Model (DEM) using SRTM or Google. What I like about Locus Map is it can also do this, using SRTM, via the following setting:
Settings > GPS and location > Altitude Manager > Settings tab > SRTM Data > Replace GPS values
When I use this setting, the calculated total ascent is conservative and realistic.
I just tried the new Audio Coach and had it report Track Elevation. Over the course of a ~5 kilometer walk on nearly flat terrain, the final reported Track Elevation was 50 meters. This is far too high a value.
The Track's Statistics page shows more realistic results (using SRTM data exclusively):
Elevation (Downhill): -20 m
Elevation (Uphill): 19 m
To demonstrate the terrain's "flatness", the reported min/max altitudes are 29 and 35 meters.
Would it be possible to have the Audio Coach report Elevation according to the settings in Altitude Manager?
