Sorry to butt in, but does changing the max limit in "map.h" (to say
1000) and then recompiling have any effect on the speed / efficiency of
mapserver if you have have a map file wth only 1 - 5 layers?
I should not effect speed, but it does effect memory consumed as the
number of layers is staticly allocated. This might indirectly effect
speed but making less memory available for system buffers, but probably not.

Subject: Re: [UMN_MAPSERVER-USERS] Mapfile - 50 Layers Maximum ?

Randy,
The limit is set in map.h
You can change the limit and recompile
More resent version have a higher limit I think, but I'm not sure what.

Greetings,
I've come across this rumor/fact, that there is a maximum of 50
layers in a
map file. Unknowingly I was experimenting the use of MapServer for
QC'ing
a project, that I put in 2,500 layers into a mapfile. Yes, not
surprisingly
MapServer baucked about this. Then the first question is what is the
limit,
then I found out that it was 50!
I looked in to an existing mapfile that we have and it has 45
layers. These
layers are represented at different scales, and/or by spatial reference
(i.e. Indices for different UTM zones), then a watermark.
We are moving into more global datasets which may be represented the
same
way. There's 60 UTM zones. So the 50 layer limit is going to be a
problem
in the short term.
Can anyone verify this fact? And is there a work around in place to
accomplish these needs?
Thanks, Randy ________________________________________________
