[Qgis-user] Problem styling OS Mastermap

[Thomas Colley]

Hi David

I think all of the published OS styles use a field called os_cat that
doesn't actually exist in the data as standard, it has to be calculated
based on the values in several other fields. 

There should be some sql scripts with the styles you downloaded, that
can be used to create the os_cat field.

Hope this helps.

Tom

Subject: [Qgis-user] Problem styling OS Mastermap

I have been trying to load and view the sample of OS Mastermap provided
on the OS website.
Although I can load it successfully into QGIS 2.0.1, under Windows 7
Pro, I cannot get any of the published styles to work.
I have tried the OS provided style, and the Warwickshire County Council
styles from GIThub. I have also tried converting the .gml/.gz files into
.shp using the OS converter experimental plugin, and applying the
Warwickshire styles again.
At each time the initial files load into the QGIS Mapview pane. I then
try loading the style files, and these appear properly in the Map Legend
pane, but the Mapview pane goes completely blank, with a white
background. However the cursor is still displaying the correct
coordinates in the status bar, despite the blank map.
Unchecking all but one of the layers has no effect, and changing the
layer order also has no effect.
Can anyone please suggest where I am going wrong?
