Hi All, Since it seems to be an issue for more than one MapServer user to improve the performance I was wondering if anybody of you know some good sources for getting topographic features in different spatial resolutions? Lets say the roads in 1:5,000,000 1:1,000,000 1:100,000 or something like that? I actually don't know how to get such data sets. Assuming we had it it wouldn't be a problem to use scale dependency in different layers.
