I want to import a GPX file to create a 3DC CompuTrainer course, but the file is missing elevation information.
Because the GPX file contains Longitude/Latitude data, PerfPRO can determine what the elevation is for each point and set an elevation. PerfPRO pulls SRMT elevation data from the USGS website to make this happen. It determines what data files from the USGS website are needed, downloads them, then matches the lon/lat data from your GPX file with the USGS data and gives you your profile.
