DEM is a map with elevation data built into it.
Install the latest software to your watch to use this feature..
How accurate is GPS elevation?
It is true that GPS elevations are less accurate than the horizontal positions gained from GPS. In fact, GPS elevations generally have two to three times the error of horizontal positions gained from GPS. Even so, there is a tremendous value to the elevations provided by precise, carrier-phase GPS observations.
How elevation gain is calculated?
For example, consider a mountain whose summit is 5,000 feet (1,500 m) in elevation, but somewhere on the way up, the trail goes back down 250 feet (76 m). … If one hikes over five hills of 100 vertical feet each, the cumulative elevation gain is 5 × (100 feet (30 m)) = 500 feet (150 m).
