Then there are more nuanced reasons for waypoint transfer. In some remote parts of the world, however, the GE images might be notably more detailed than available charts, so it remains something to keep in mind for all vessels.Ħ. This might be an advantage for a small boat trip, going in and out of places that are not charted to the detail you want, but for a larger boat trip, it is generally best to do the layout on the RNC version of a nautical chart showing all navigation aids, because we want to coordinate our waypoints with nav aids when possible. In a pinch, you could also use GE to lay out your route and then export that in a format that can be imported to your onboard GPS. Needless to say, all we discuss here applies to a bike trip or hike as well as a voyage.ĥ. The GE display of your route on a satellite image gives a wonderful perspective of your travels. Google Earth (GE) makes it very easy to post a track or set of waypoints online that can be viewed privately by selected contacts or published to the public. You may want to share your voyage with a friend or the public by posting your route on the Internet. This calls for getting the saved track out of the onboard GPS and into your computer.Ĥ. After a cruise or race is over, you may want to document where you were and save it as a record for future use, or go back and see what you might have done right or wrong in a race. Also, with the data in a handheld, you can have several folks watching the navigation from the deck, and not rely on just the ship’s display screens.ģ. Racing or cruising, it could be crucial to be ready to go with the next waypoint and present tracking in case the main system fails. Once you have a set of waypoints in your onboard system, it is always valuable to back up the waypoints by installing the same route on at least one handheld GPS. In the next column, I will discuss the pros and cons of ENC vs. This is one more reason to lay the route out on a computer and then transfer it to the onboard system, because the internal charts of dedicated GPS systems are all vector-based. actual graphic image of the printed chart (called RNC, for raster navigation chart) rather than on a vector chart (called ENC, for electronic navigation chart). If I might insert here an easily defendable bias, the electronic route layout is usually best done with a “real e-chart,” i.e. Then, when your final list of waypoints is made and checked, you can transfer the list to your onboard navigation system using methods we discuss here.

These programs (including many free or open source versions) have better graphics and view options than any dedicated onboard system, not to mention that many show tides and currents as a function of time to help plan the route. The easiest way to lay out a route is to select and then fine tune the waypoints on an e-chart program on your computer rather than enter them directly into the onboard GPS. There are many reasons these days to transfer navigation data among GPS and e-chart devices. GPX Viewer is highly customizable.Your best bet for nav data transfer (published November 2012) notification when GPS position is near waypoint with adjustable distance with follow GPS position and rotate map features, GPX Viewer can be used as a simple navigation tool rotate map according to device orientation sensor or according to movement direction data from GPS follow GPS position continuously by adjusting map position OpenWeatherMap weather layers and overlays online maps such as Google Maps, Mapbox, HERE, Thunderforest and some others based on OpenStreetMap data, : colorize track and route line by elevation, speed, cadence, heart rate or air temperature analyze information for waypoints and adjust their icons view graphs of other track data like cadence, heart rate, power and air temperature view graphs (charts) like elevation profile and speed profile for tracks and routes analyze information and statistics for tracks and routes compress gpx files into gpz and kml files into kmz (zip archives) file browser which opens multiple files and has support for favorite files and history view tracks, routes and waypoints from gpx, kml, kmz and loc files GPX Viewer is the ultimate GPS locator, GPS tracks viewer, analyzer, recorder, tracker and simple navigation tool for your trips and outdoor activities.
