[Mapserver-users] Re: help me !!!

[Dylan Keon]

Dharani,

I haven't played around with tiger line data.  You probably just need to 
set LABELITEM for each layer, then define a LABEL object within each 
CLASS.  Here are a couple of posts from the archives that might help:

http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0301/msg00553.html

You might also find some clues on the OGR howto page:
