I have several routes I am calculating elevation stats for. What I want is Total Ascent/Cumulative Gain, where all ascents and descents are accounted for. As opposed to solely the difference between the min and max elevations. https://en.wikipedia.org/wiki/Cumulative_elevation_gain
Where Climb (total ascent?) is just maxelev-minelev + descent. I've been able to verify these numbers by exporting the z values to spreadsheet and using the same formula.
My dilemma is when I check these paths in Google Earth: the profiles, max, and min are all the same, but the elevation gain/loss appear wildly different. For example, for the fourth record above Google Earth provides a gain/loss of 369/99.
Is there a something conceptually I am not understanding?
