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

Aihe: Re: [mapserver-users] Ogrtindex and attribute data
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?
Regards,
Christy

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.
