What Was Used For Editor Map (ATS)

[Calhon]

Hello,

So I was in the middle of starting off a small map, and I was rather stumped to find that in usa.dds, SCS did not use mapa.cz or Google Maps? Does anyone know what on earth they did use? When I go to use an image, its completely out of place.. I am trying to zoom in one of the states, by pasting over one of the states onto the original one. However, it is not fitting with the Cali/Nevada roads..

Thanks
