[mapserver-users] Ogrtindex and attribute data

[Rahkonen Jukka]

Hi,
 
It just - starts to work.
 
I need to write a hundred more answers on this list before I have paid back this help. And Jeff, do you hear me?  I copied my settings from a document http://mapserver.org/input/vector/ogr.html.  Obviously it should be updated a bit.  I should have read http://mapserver.org/optimization/tileindex.html instead.

	What happens if you leave out the CONNECTIONTYPE when you use the tile index?
	
	i.e.:
	
	LAYER
	  TILEINDEX "wildwater_tindex.shp"
	  TILEITEM "location"  # not needed if the attribute with the data paths in your index is called "location"
	  CLASSITEM "luokka"
	  ...
	  CLASS
	     NAME "wide_wildwater"
	     EXPRESSION "36311"
	     STYLE
	       COLOR 255 0 0
	       WIDTH 2
	     END
	  END
	END
	
	I'm not certain if leaving the connection type out will help, but it's not necessary assuming your data are all shapefiles.

		Hi,
		 
		If I use a big combined shapefile as input I am getting class 36311 coloured as red.  If I am using tileindex I am getting an empty map.  Tileindex itself is working and if I comment out the EXPRESSION while using tileindex I do get everything from the background data drawn.  Thus it is the classification that does not work for me.
		My Mapserver is version 5.2.1 and here are some parts of my mapfile:
		 
		 
		  #CONNECTIONTYPE OGR
		  #TILEINDEX "wildwater_tindex.shp,0"  #classification does not work with this
		  
		 DATA "combined_wildwaters"   #classification works with this
		 CLASSITEM "luokka"
		................................
		  CLASS
		     NAME "wide_wildwater"
		     EXPRESSION "36311"
		     STYLE
		       COLOR 255 0 0
		       WIDTH 2
		     END
		  END

			Hi,
			
			Do you mean that you cannot classify a layer where the data are drawn using a tile index?  I use tile indexed shapefiles all the time and have never had any problems using CLASSITEM/EXPRESSION and FILTERITEM/FILTER.  Could you provide an example of what's not working?

				Hi,
				 
				Can somebody affirm that using ogr tileindex is breaking the access to the attribute date of the real datasets, for example shapefiles?  Somebody was trying to use WMS GetFeatureInfo with a ogrtindex layer and failed and so did I in the test I made for verification.  Now I have been trying myself to classify an orgtindex layer but CLASSITEM/EXPRESSION does not select anything. FILTERITEM/FILTER does not work either.  Both systems work if I change a huge combined shapefile in place of the tileindex connection and without EXPRESSION or FILTER Mapserver is drawing all the features OK.
				 
				If access to attribute data is not implemented, wouldn't it be cool to have it?  Multigigabyte shapefiles are tedious to update but I have a reason to use files instead of a database in this case.
