Thanks for soon answer and idea, how to split regions on the map.
But I still thinking, why I can`t increase MS_Maxlayers: then I try to =
increase MS_Maxlayers, nothing changes. When I decrease MS_Maxlayer to =
15, my smaller map (~20 layers) doesn`t work (same error - msLoadMap(): =
Unknown identifier. Too many layers defined). Compilation with increased =
MS_Maxlayer doesn`t give any errors... Maybe MS_Maxlayers depends on =
MS_Maxclasses, or on something else?

Hi Vaidas,
with tileindex user can see all data across the all regions as =
seamless dataset. It may be useful for you - or not? If you can choose =
only one region and display it, you can do it by changing underlying =
dataset names (or paths) on-fly using cgi variables, e.g.
map_yourlayer_data=3D"/region2/pylons"
It requires probably more javascript in your page to switch the =
desired region. But you will have only 3 layers in your mapfile.=20
(About compiling mapserver - We were successful with increasing the =
number of layers as well as classes etc. I don't know, why it doesn't =
work.)

P=F8edm=ECt: [Mapserver-users] Too many layers
I`m sorry for my poor english:)
Mapserv returns such error line: msLoadMap(): Unknown identifier. =
Too many layers defined
I have map of electricity supply system, in wich are 3 basic =
elements: lines, pylons and substations. But all the electricity supply =
system I must graduated by regions: one layer - one basic element in =
that region. So, for one region I have 3 grouped layers. In map, user =
chooses, wich regions (grouped layers) he wants to see in map. There are =
~42regions, that equals 126 layers.
How can I make my mapserv work?
In previuos posts I read about tileindex. But in my case, I think, =
that doesn`t work, because with tileindex user in map will see only 3 =
layers: lines, pylons and substations, and can`t choose any separate =
region. Or i`m I wrong?
Besides, I can`t compile map.h file (now MS_Maxlayers=3D100): when I =
compile map.h with MS_Maxlayers=3D400, mapserv returns the same error. =
What can be wrong?
Thanks in advance,
