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 track in Australia hosts series like the V8 Supercars. I included
an overlay, 3 polygons for track configurations, 2 paths for pit road
options (2 different paddocks), and placemarks for each turn. I then
added information for a nearby kart track. That includes 8 polygons for
track configurations, a path for pit road, and turn placemarks. You can get the KMZ set here.
