[mapserver-users] SIZEUNITS set to meters

[Håvard Tveite]

I have not tested this for sizeunits meters, but for pixels
you need to set style MAXWIDTH (or MAXSIZE).

At small scales (1:10'000), this is working great, the roads is well-sized regarding its real width, but as soon as I zoom in and have a larger scale then approximately 1:5'000, then this is not working anymore and the line width stays constant the more I zoom in.
