Map Interface to USCG Light List

Find Aids to Navigation within Search area and Create GPS .gpx file


This is the map interface to a set of tools that will generate GPS .gpx files for a set of selected waypoints. By zooming in to your area of interest and clicking twice on this map, you define a rectangle. All the Aids to Navigation markers within that rectangle will be displayed along with a list of the charts that have overlap your rectangle. You can follow the link to the chart list, or use the list showing only the aids within your rectangle. Check the aids you want to become waypoints and then click the submit button. You will then be on the bulk waypoint and route editor. Once you rename your waypoints as desired, you can use those names to create routes in your gps for your desired courses. When you are finished, click the submit button and a .gpx file will be downloaded to your computer. If you click in error, just click twice again, only the last two clicks count.


Zom and pan to your location then click twice on this map to define the area of interest. One click should be on the upper left corner and the next on the lower right corner of the area you are interested in. Make sure all your desited marks are inside the rectangle defined by your two clicks. If you click in the wrong place, try again. Only the last two clicks are important. When you are done, click SUBMIT.

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.
