[mapserver-users] displaying LINESTRING elements from shapefiles

[Rahkonen Jukka]

Hi,

This layer shows OSM roads for me from the same shapefiles that you are
trying to use. 

LAYER
        NAME "OSM_roads"
        STATUS ON
        DATA "d:\Data\OSM\roads"
        TYPE LINE
        UNITS METERS
        METADATA
          "wms_title"    "OSM_tiet"
        END
        CLASS
        NAME "roads"
        OUTLINECOLOR 0 255 0
        END
        PROJECTION
          "init=epsg:4326" 
        END
  END    

Check that EXTENT in your mapfile suits the data.
