GPS GPX Batch Waypoint and Route Creator
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.
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.

Edit Your waypointsMost latitude and longitude formats are acceptable. ddd.dddd, ddd mm.mmmm, or ddd mm ss.ssss all work. You can use negative numbers or NSEW designations. You can also put both latitude and longitude in the latitude field separated with a comma leaving the longitude field blank. Final data is always (-)ddd.dddddddd

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
