Hello List, 

I'm trying to display the S57 Soundings values on my map. Here's the output
of ogrinfo on the SOUNDG layer of my S57 chart (the relevant part, for 1
feature):

OGRFeature(SOUNDG):140
  RCID (Integer) = 141
  ...
  MULTIPOINT (-72.373733104642483 46.402858362124853 9.5)


I can display a SYMBOL at the appropriate coordinate, but what I need is the
actual Z value... (9.5) Anyone can help me accomplish this? What should I
put as a LABELITEM? Here is my layer definition:

   LAYER
    NAME SOUNDG_4
    TYPE POINT
    STATUS ON
    CONNECTIONTYPE OGR
    TILEINDEX "SOUNDG_4.shp,0"

    LABELITEM ???????

    CLASS
    	COLOR 0 0 0
    	SIZE 4
      SYMBOL default-circle
	
	LABEL
	  COLOR 0 0 0
	END
    END
   END # Layer   

Thanks a lot!
