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 found 7 layouts and two pit roads for the main track, a dirt speedway oval, and what I think is an RC track with 11 more layouts. I provided turn data for each and length notes for each.
Please note that I have stopped measuring paths and polygons and GE 5.2 now provides this data for me. Also, you will find that GE 5.2 can profile the paths (pit roads here).Unfortunately, it can't profile polygons, at least yet.
