----------------------------Original message---------------------------- I am looking for maps of the mountain passes between Argentina and Chile for a study to promote economic growth in the region by improving transport corridors. Any digitized maps suitable for use as GIS layers would be great, but I'd be just as happy to get paper maps at better than 1:1,500,000 scale. I know the more traditional sources for satellite imagery, but as this is an international development project funding is very limited for map purchases. Any tips you might have would be greatly appreciated. Thanks! Michelle Morgan ([log in to unmask])
