[mapserver-users] MINSCALE/MAXSCALE for CLASS???

[Steve Lime]

The main reason is performance. It's much more efficient to make scale
based decisions at the layer level
rather than having to get a feature, classify it and then dump it
because of scale considerations. It could
be added but I would advise against using it. Other thoughts?

Steve Lime, et al,

Is there any reason why MINSCALE/MAXSCALE couldn't be added to the
CLASS
objects? It would greatly simplify creating the mapfile in many cases.
A
lot of my LAYERs are the same data only difference line weights at
different scales.

Could we do something like CLASSITEM "{scale}" or whatever then use
EXPRESSION to select on it.

Anyway, food for thought . . . back to building another mapfile.
