[mapserver-users] Coloring vectordata by features/infos

[Robert Sanson]

Hi Michael
 
Take a look at CLASS and EXPRESSION: http://mapserver.org/mapfile/class.html 
 
Here is an example from one of my map files:
 
LAYER
  NAME rivers
  GROUP "Topos"
  TYPE LINE
  STATUS ON
  DATA ../data/aus/rivers
  PROJECTION
   "init=epsg:4283"
  END
  MAXSCALE 10000000
  MINSCALE 75000
  CLASSITEM "PERENNIAL"
  CLASS
    EXPRESSION /1/
    NAME "Permanent"
    STYLE
      WIDTH 2
      COLOR 115 178 255
    END
  END
  CLASS
    EXPRESSION /2/
    NAME "Seasonal"
    STYLE
      WIDTH 1
      COLOR 115 178 255
    END
  END #CLASS
END
 
Regards,
 
Robert

Hmm, any hints for what I should search for?
