Styled Layer Descriptors (SLDs) for vector products

A Styled Layer Descriptor (SLD) is an XML schema specified by the Open Geospatial Consortium (OGC) for describing the appearance of map layers.

Ordnance Survey use SLDs to style vector products in the OS OnDemand Web Map service (WMS) to display a specific map layer as a raster image. Subject to licensing, these are available for you to download and use, free of charge, in order to style Ordnance Survey datasets for web or GIS use.

SLD’s may be amended from time to time, for example where a product specification is changed.

For additional assistance please read the Frequently Asked Questions then contact us.


Download and Licensing

Please click on the relevant vector product below to download the SLD file pack. Each pack contains a SLD code template with associated meta data (and for OS MasterMap Topography Layer additional pseudo code) and a readme licence file.

By downloading the file, you are accepting the terms in the accompanying Styled Layer Descriptor licence.

The licence sets out the terms on which you may use Ordnance Survey Style Layer Descriptors and any related pseudo code.

Please note:

  • You must hold a valid licence (including any OS OpenData Licence) for any datasets to which you apply the SLD code.

  • The licence terminates automatically on the termination of your licence for the applicable dataset
