Thank you for your post. Don’t mind that map. It isn’t actually what I’m after. I was just trying to show people who don’t understand the task, that the map doesn’t matter. I could georefernece anything. I could do that map and make it useful in my Garmin and be able to see how close I am to the nearest restroom, or what path will take me fastest to a particular ride, etc. I’ve done that for larger parks and even with a similar animated map of Rome back when Google Maps and smartphones weren’t a thing. I could use a Garmin Colorado and a map that I georeferenced as a KMZ in Google Earth.
Like you, I need to do this in PDF for use in Avenza now. If only I could find an app that would support graphical KMZ overlays, I’d be satisfied.
