[Qgis-user] Help with Ordnance Survey SLD's for OS Mastermap

[McDonaldR]

You can grab QGIS styles for OSMM here:

https://github.com/mixedbredie/QGIS-styles/tree/master/OSMM

and here:

https://github.com/QGIS-UK/Styles/tree/master/OSMM

The QML and SLDs depend on the schema of the source data (GML, shapefiles) and how they are loaded into the database (Loader!, GoLoader, Productivity Suite).  Usually descriptiveterm, descriptivegroup and make are used for the styles.

These SLD files for OSMM are based on the OS styles but without the reference to os_cat field.

https://github.com/mixedbredie/Geoserver-OS-SLDs

hope that helps a bit.

os_cat is a field used for styling in OS layers. The complication is (at least last I checked) the field doesn’t exist in the data as shipped. There are some SQL files on the OS website for creating os_cat (calculated from a combination of other fields) in PostGIS, but I’m not sure how that would be applied to shapefiles.

I’m sure that OS have released proper QGIS Style Files now as well as SLDs. I can’t find them at the minute (too early on a Monday morning) but I’ll let you know when I do.

Cheers

Tom

Hi David,
IIRC that kind of variables are not supported by QGIS neither by the SLD standard.

You must replace it with the correct SVG filename.

Anyway, what is "os_cat" supposed to be? Is it a layer's field name?

Regards.

I'm very much a beginner with QGIS and I'm trying to run long before I
can crawl ...

I'm trying to use the Ordnance Survey MasterMap Topography layer SLD's
(from
http://www.ordnancesurvey.co.uk/docs/styled-layer-descriptors/topography-sld.zip)
to style the sample OS MasterMap data.

Initially, I found that when I loaded the SLD file into QGIS, only the
first rule was being picked up, but eventually I found tjmgis's answer
in
http://gis.stackexchange.com/questions/69854/styling-os-vectormap-local-in-qgis
(that all the <FeatureTypeStyle> and </FeatureTypeStyle> except the
first and the last in the SLD files need removing) and now I'm making
progress.

I'm struggling with one problem: there's a rule called
<Name>Vegetation (pattern) - 1:35 to 1:3,496</Name>
which specifies the SVG file as
xlink:href="osmmsymbols/${os_cat}.svg"/>

QGIS is showing me question marks in these areas (which I think means it
is not finding the SVG file).

Does QGIS support this use of ${os_cat} (and if so, what do I need to do
to make it work?) or do I have to replicate the rule with explicitly
named SVG files for all the different vegetation types?

David
