Second, these files are still sometimes the only output from GPS receivers, GPS phone apps, fitness apps, or other mapping tools. Why bother with GPX files today? First, comparing raw GPX files to mapped GPX files is a simple, clear way to explain why mapping adds value. Much has changed over that time: Educators and students now have a myriad of types of files and objects in those files to map-points, lines, polygons, grids, images, and more. I used them extensively in the many geocaching courses that I created in city parks, riparian zones, field lab sites, and elsewhere for years to foster spatial thinking. The actual GPX file contains hundreds more GPS points as latitude-longitude values, each coordinate pair occupying one line in the data file.įifteen years ago, GPX files were one of the few types of files that were mappable. You can see the latitude, longitude, elevation, date and time, and other information at the time I collected this particular information (when I was teaching on the campus of Oklahoma State University). In a text editor, a GPX file looks like this, below. Mapping the output from these files in ArcGIS Pro and ArcGIS Online is straightforward using the methods described in this essay. GPX files, in GPS Exchange Format, are text files in XML format containing geographic information such as waypoints, tracks, and routes, as real-world coordinates.
