GPS GPX Batch Waypoint and Route Creator


NOTE:

Notice. I gotten two error reports on this page. There is not enough information in the log to know why this happened. Please use the CONTACT page to let me know the details. I apologize for the inconvenience.

Notice #2. This page works for about 500 waypoints. It has been reported that it does not work for larger files. If you have an error with a file smaller than that, please let me know at the contact above.

This page is a .gpx file batch creator and editor. You can create or edit waypoint and routes and write the output in .gpx format. The .gpx file is a standard format that can be downloaded to a GPS device with a number of programs. One free program that works well is EasyGPS. You can either enter your waypoints by entering the latitude and longitude on this page, or you can start with the output from another program that outputs .gpx files like OpenCPN and load that file. The easiest way is to use the Light List Map program HERE. Either way, edit the names of your waypoints to more user friendly names in the form below and then use those names to create your routes in the text box at the bottom of this page. Hit the submit button and a .gpx file with your waypoints and routes will be downloaded to your computer. Upload or save it to your GPS and you are ready to go sailing. Note, some GPSs have limits on the number of waypoints or routes. You may want to save your existing .gpx data and then clear the memory before loading this file. I recommend having separate .gpx files for each race or occasion so that your waypoints and routes are easier to activate on the water.

If you came to this page from the Light List selector pages, your waypoints will be filled out below. You may add a file or blank spaces if you wish by entering the file name and number of blank spaces and clicking the submit button just below. Otherwise you can optionally edit them to more user friendly names. Then enter your routes using the names you entered and click the submit button at the bottom of the page.
