Carola,
Another idea with roads is that you show major highways when zoomed out
and increase detail as you zoom in. The best way to do this is to
create separate shapefiles and layers and display them based on scale.
Of course, it you just use the same roads shapefile and use classes to
pull out the major highways, you are only going to slow things down even
more.
We (as in, the company I work for) does this already. I defined the
layers so that they are drawn at different zoom levels (and they are all
different .TAB files). However, this has a few drawbacks:
- The layers aren't simplified. As in, when you start drawing a layer,
you (mapserver ;)) draws it all
- The .map file grows in size and becomes harder to handle
On a side note, can anyone give me an overview of all scripting that's
possible in a .map file? Like I said, it's growing and I would love to
use at least SOME dynamic stuff in it...
