My name is Will Pittenger. I have been making KMZ sets for Google Earth for a long time. After I starting making those, I wanted overlays for my sets. I was unsatisfied with the accuracy of the images available at Wikimedia Commons. So I started making my own with Inkscape and uploading them. Then I needed a place for anyone that liked my KMZ sets and/or maps to find others. For a while, a simple blog sufficed. But, once I started getting requests, I knew I needed something better. This site is the result. You are welcome to set up an account. Some activities are for registered users only. Take your time poking around and let me know what you think.
I made a KMZ set for you before it vanishes from Google Earth. It includes 3 overlays, dozens of paths for layouts, turns, distances, and more. You can get the KMZ here.
I know, atleast they're keeping the design sothat it could technicaly be copied exactly anywhere in the world. Won't happen anytime but it's better than the many tracks we've lost in the years past.
Iracing, the single most realistic racing simulation in the world, is going to make an exact copy of the track for their game using their laser guided measuring system. Here you can see what other tracks they offer and which they should have to offer in the future. Here
