GPX, or GPS Exchange Format, is an XML schema designed as a universal format for GPS data. It allows for the description of waypoints, tracks, and routes. Its importance lies in its ability to standardize GPS data, making it easier to share, store, and use across various devices and software applications.
Basecamp works, you just import the gpx, click on the track and click "convert to route". Then you can send the route to your gps, on my 2597 the route shows up in the trip planner app. I just played with mappite.org. It works pretty good, and I put the gpx directly into the GPS's gpx folder and it shows up in the trip planner.
The tool converts the point data in a .gpx file to features. A .gpx file stores points as waypoints or tracks. Waypoints are generally single unrelated points, while tracks consist of a route or collection of related points with a start and end point. The type of point collected is specified in the output Type field by the values WPT (waypoint
Typically the file created by the export operation will have a ".usr" suffix if is a native format or a ".gpx" suffix if is is a GPX format file. Lowrance units currently use five different versions of USR files. These different USR versions store the four internal elements (waypoints, routes, trails, and event marker icons) using different Step One: Add GPS Tracks, Waypoints, and Routes. Collect tracks, waypoints, or routes using your GPS device. To add them to your ArcGIS Online web map, export the data from your device as a GPX file—the GPS Exchange format. How you create the GPX file will depend on the GPS device and software you use. For the purposes of this tip, a Garmin . 221 142 24 176 283 257 160 288 280convert gpx waypoints to track
