eGPXviewer is a GPS track viewer capable of summarizing key data of input track GPS series, displaying the track's altitude & speed profile and provide interactive 3D perspective views of it. The GPS track data should be input from a GPX exchange formatted file which is typically obtained by downloading a GPX file from a GPS receiver/tracker (e.g. Garmin™) or an iOS™/Android™ tracker app. The GPX exchange format is a standard output file format available in most GPS tracker devices/applications. It is human readable text file written in XML. Read more about the GPX exchange file format here https://en.wikipedia.org/wiki/GPS_Exchange_Format. eGPXviewer is currently available for Win10 and Linux (Ubuntu/Mint, CentOS, OpenSUSE, Raspbian) operating systems. ™ Registered trademarks for the respective owners.
