This plot was made by DeLorme Topo North America version 10.0 mapping software from data collected by the DeLorme PN-60 GPS.
I have used the PN40 (earlier model) for years and love what the pair can do.
The graph shows the profile (elevations) and the speed….
The graph and map are correlated so you can see speed and elevation locations.
Additionally, you can download old GPS TOPO maps that show older roads, mines, adits, ruins and other things lacking on most digital versions.
The first 3D is the digital rendition, the last 3d is the scanned UGSG Topo’s on the 3D projection
