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.
Turns out I was mistaken. I didn't have a local copy, but I it post a set some time ago. This version adds the new overlay and length meaurements. I also noticed an odd detail in the entry area for the pits that resulted in three possible versions. Two add chicanes, but no length. In fact, all use the same pavement.
I completely redid my map of the circuit that Formula 1 and CART used
in downtown Detroit. The new image includes local streets, a scale, and
more. As a result the overlay in this set has been updated.
