This proved to be easy using Garmin's free software — BaseCamp. Here's how to do it.. Go to Butch's Indiana Railroad Maps and download the desired kmz file.
Many kmz files on the net do not meet this criteria, so be careful when downloading from another site. The initial window will appear similar as shown below:.
The window will appear similar to the image below — a bunch of waypoints and a track. Now, use BaseCamp to create the route that your Garmin can recognize. If you have multiple maps loaded onto your device use the internal menus to select which map to actively view. With so many maps to choose from on this website and available from Garmin you're likely to have multiple maps loaded on your GPS receiver and you'll need to turn some on or off to show or hide different maps.
This is most obvious when you have a topo showing and want to show City Navigator, or you have a topo showing and need to see another topo map. This tutorial will walk you through how to show or hide maps on some of the most popular series of GPS units. Even if your unit isn't listed specifically it should be very similar to the steps listed for these series:. The process may vary slightly based on which profile you are using and which unit. If you have a Garmin GPS unit, you can create and download custom maps onto your unit.
When you use the CalTopo website, these custom maps can be almost anything that you can imagine. Custom maps have been available for Garmin GPS units for quite some time, but the process was clunky and tech-heavy. Today, using CalTopo, creating custom maps is dead easy. Update: You now need a CalTopo Pro account to create custom maps this way. If you need custom maps, I consider it worth the subscription cost. Additionally, CalTopo is a powerful tool that probably has many other potential uses for you.
You can explore the tools and layers of CalTopo on their tutorial page. So what is a KML file? Those coordinates are used by your Garmin GPS to overlay the images when you look at it on the unit.
