+rakeck Posted June 30, 2013 Share Posted June 30, 2013 (edited) I thought this would be a simple web search that would yield a number of paid and free apps, but .. If I have a .gpx file from a Garmin device that contains elevation data (altimeter), and I'm looking to replicate real-world documented data as closely as possible, and I've determined that one "benchmark point" (summit) in the path file is 20 feet too high, how can I programatically modify all the elevation points in the gpx file to be the original elevation value, minus 20 feet? I don't mind paying a reasonable amount for an app that works well. Thanks Edited June 30, 2013 by rakeck Quote Link to comment
