GPX GPS Exchange Format File Format Description
GPS exchange files, .GPX files, are created from GPS devices.
File Structure
GPX files are XML format text files. The .GPX files can contain way points, routes, tracks, and various attribute information. GPX files use the World Geodetic System 1984 coordinate system.
-
Way points describe an unrelated group of points. For instance, this can be a collection of place names. Each way point is imported and displayed as the default symbol.
-
Routes are a series of connected way points. Typically a route is a plan on where to go. Routes are imported and displayed as polylines. One-point routes are imported and displayed as the default symbol.
-
Tracks are a series of connected way points. A track is where the device has actually been. Tracks are imported and displayed as polylines. One-point tracks are imported and displayed as the default symbol.
Remarks
The way points, routes, and tracks in a GPX file are imported into a single group in the plot.
Grapher does not import .GPX files with World Geodetic System 1984 coordinate values. The .GPX file will be displayed with page coordinates in the correct relative positions. Grapher does not export .GPX files with World Geodetic System 1984 coordinate values.
