Help with DEM elevation data
« on: June 15, 2009, 06:11:34 AM »
Scott,
I must be doing something fundamentally wrong in trying to experiment with DEM data.  When I load a tcx or GPX file, change DEM parameters and hit "Add Elevation to Track" I don't see any change in the "Climbing Elev." field on the summary line.  Is the DEM data actually being loaded, but this field doesn't get recomputed?  I've got Data Source set to DEM and am experimenting with Minimum Gain and such.  The Presets field is set to "TopoFusion".  Dem Source is Download/Cache, force SRTM.

If you download (assign) new DEM data to the file, the total should update in the main form (unless it already had DEM data assigned to it, of course).  However, the method that the main form uses to compute elevation gain is always the same.  Those settings (like minimum gain) only effect computations in Climbing Analysis itself.

Hope that answers your question.
