[mapserver-users] Can't draw points from shapefile

Sat Aug 3 08:59:51 PDT 2013

Thank you for your valuable response. 
I've struggled through 25 layers in an existing .map file, some defined as index shape file coverages andnow I think I have them all properly configured. Most of the problems were deprecated syntax, bad pathsin index shape files or scale related omissions I've learned to overcome with mapserver Url parameters.
Thanks to all the helpful tips I've received on this challenge.

    Michael,

        A minor point: Change UNITS DD in the map portion (UNITS,
      EXTENT, and PROJECTION are all related). 

        But the basic problem is a lack of a SYMBOL object in the STYLE
      object of the points layer.  I didn't think it was necessary (it
      wasn't in some previous versions?).  Back in the day, I thought
      the default was SYMBOL 0 which was defined as a filled circle
      therefore no explicit definition or reference required in the map
      file.  It looks like this is no longer the case.

        So the solution is to add a symbol definition to the map file
      (between the WEB and LAYER objects):

        #Circle symbol

        SYMBOL

          NAME 'CIRCLE'

          TYPE ellipse

          FILLED true

          POINTS

            1 1

          END

        END 

      and add a reference to it in the LAYER's STYLE object:

                  STYLE

                      SYMBOL 'CIRCLE'

                      COLOR        255 1 1

                  END

      Best Regards,
Brent Fraser

        Does anyone see a problem with the hwypoints layer?

        What is the minimal layer definition to display shapefile
        points?

        Thanks

        PS - shapefile points draw in QGIS.
