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.
This circuit in Dubai (part of the United Arab Emirates) has a full-sized track with six layouts, an outdoor karting track, and an indoor karting track. It is also part of a larger facility called Dubai Autoworld which is supposed to include hotels, condos, and a theme park with a racing theme.
I included overlays for each layout of the main track, turns, layouts, and more. You can get the set here.
