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

Tue Dec 2 16:12:02 EST 2008

If you set the layer status to ON or OFF, your 'gps_point' layer won't
show up on the map (at the default, unintended location) until you add
the layer name explicitly in your URL call.

	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

	URL:

http://10.65.192.1/cgi-bin/mapserv.exe?mode=map&layers=linz_orthos+crs_p
arcels+gps_point&map.layer[gps_point]=FEATURE+POINTS+1748637.58606+54390
01.11023+END+END&MINX=1747637.58606&MINY=5438001.11023&MAXX=1749637.5860
6&MAXY=5440001.11023&mapsize=1200+1200

	regards,

	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.

	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=5427898.9
9793&mode=map&layers=linz_orthos+crs_parcels+gps_point&MINX=1747411.1398
5&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
