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.
Hi! I'm from Porto, Portugal (Oporto if you prefer).
I'm writing to express my thoughts about a very odd issue. Please, try to separate the large layout from the small one (not from the drawing, but from time itself). The Circuito da Boavista was held back in the 50's every 2 years. It had the last large event held at 1960, the event was never held again until 2005 when it revived by the city Mayor.
Back then, the layout used had a length about 7km. Upon it's revival, the layout was shortened around 3km. The confusion resides on Esplanada do Rio de Janeiro. The layout is completely wrong, it used to be a straight, now it's curved because the area was recently rebuilt precisely to create a larger esplanada and beach area. There seems to be a lot of confusion over the hundreds of layouts I've been able to visualize, and most of then tend to misdesign this particular arror, like you did.
