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 expect to update this in a year or two. This track supposedly being
extended. So once Google Earth shows the extension, I may revamp this
set and add some more overlays.
For now, I am including 3 map
overlays, 5 polygons for track layouts, a path for pit road, placemarks
for each turn, notes on what I think will be the extension, and more. You can get the KMZ here.
