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.
Older maps published on Commons were Public Domain. However, my recent maps use Creative Commons Attribution Sharealike 3.0. You can distribute it all you want and even make changes (derivatives). However, you must give me credit for all such images. Furthermore, the license is "copyleft" (the Sharealike part). That means that the CC-BY-SA-3.0 license also applies to your derivatives. You are not allowed to make your image public domain or any license not compatible with mine.
I have yet to decide on a license for my KMZ files. For now, please assume I am reserving all rights.
