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.
Actually, I made two maps. Normally, with street circuits, I include the streets, but Monaco was too crowded even before I added streets. So I compromised. One map doesn't have anything other than the track. It shows what I would do for a non-street circuit like Silverstone. The other takes that map and makes it a partially transparent layer on top of the streets. Those that open the SVG up in Inkscape will find they can turn the track layer off to view just the streets.
Two notes:
Accuracy was seriously comprised by the shear vertical nature of Monaco. Everything is stacked on top of something. I located most of the track OK, but the streets were a pain to decide what connected to what. Too many roads simply vanished into what looked like tunnels.
Speaking of tunnels, the tunnel on the route below the hairpin left me guessing about the location of the track. I had similar problems in the squares.
