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.

Aihe: Re: [mapserver-users] Ogrtindex and attribute data
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?
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.
