I have been given some shp files to be displayed using Mapserver. Until now I was able to find the correct projections, display the map, and show labels. However, I have problems with polygon colors. When I set COLOR to any value, the entire map is filled with that color.

Is it a problem with the shp file, or what am I doing wrong? For example:

    NAME mylayer
    DATA "mylayer.shp"
      NAME mylayer

        COLOR 255 0 0
        OUTLINECOLOR 0 0 0

This will fill the entire map with red color, polygons have black outline.

Help! :)

Do the full map get orange if you change COLOR to 255 173 15? –  simo Feb 22 '11 at 14:28
Yes, it turns all orange with black polygon outlines. –  Palantir Feb 22 '11 at 14:33
Have you checked the polygon file in some desktop GIS? Maybe there is one big polygon. –  underdark Feb 22 '11 at 14:37
donut polygons or multi-part polygons in your shapefile? –  Mapperz Feb 22 '11 at 14:55
Often with parcels, you will have contiguous polygons that cover an entire area. If there are individual polygons for the buildings and there is a code to indicate which polys represent buildings, you can use an expression in your MapServer layer class to symbolize the buildings in a specific way. Can you post a small data sample anywhere? –  DavidF Feb 23 '11 at 16:11
