[mapserver-users] ICON Placing co-ordinates.....SOLVED

Tue Dec 2 13:06:05 PST 2008

Thanks very much David. I was just about to post a message that I had solved it. Last time I was dealing with annotation. This time a GPS point reprojected into x,y. This is what works:

Map file:

LAYER
  NAME 'gps_point'
  STATUS DEFAULT
  TYPE POINT
  FEATURE
    # This is where you specify position on the map - using a default value
    POINTS 1748411 5427899 END
  END
  CLASS
    STYLE
      SYMBOL "marker"
    END
  END
 END

Robert, 

I thought that I remembered posting an example to fix a similar issue and went back into the archives to find it.  Funny thing, it was a thread that you started!  The solution was to create the feature on the fly through a URL configuration.  

http://lists.osgeo.org/pipermail/mapserver-users/2008-September/057900.html

If you can use the URL vars in the points obj, that would be nice and clean...

David.

I am having some trouble too. I want to pass in the x y as variables. Here is the section in my map file:

 LAYER
  NAME 'gps_point'
  STATUS DEFAULT
  TYPE POINT
  FEATURE
    # This is where you specify position on the map
    POINTS %gpsx% %gpsy% END
  END
  CLASS
    STYLE
      SYMBOL "marker"
    END
  END
 END

Here is the section in my symbols.sym, file:

#21
SYMBOL
  NAME "marker"
  TYPE PIXMAP
  IMAGE "marker.png"
  #TRANSPARENT 8
END

and here is my mapserver URL:

http://10.65.192.1/cgi-bin/mapserv.exe?gpsx=1748411.13985&gpsy=5427898.99793&mode=map&layers=linz_orthos+crs_parcels+gps_point&MINX=1747411.13985&MINY=5426898.99793&MAXX=1749411.13985&MAXY=5428898.99793&mapsize=1200+1200 

Unfortunately I get an error: 

loadFeaturePoints(): Unknown identifier. Parsing error near (%gpsx%):(line 727) 

How can I pass in the x y?

Many thanks,

Robert Sanson

You'd use the icon as a symbol like so:

LAYER
  NAME 'TheIcon'
  STATUS DEFAULT
  TYPE POINT
  FEATURE
    # This is where you specify position on the map
    POINTS x y END
  END
  CLASS
    STYLE
      SYMBOL "2.gif"
    END
  END
END
