The OS OnDemand Web Map Tile Service (WMTS) delivers pre-rendered tiles over the internet making it ideal for fast data serving to external internet sites.
To use OS OnDemand WMTS you will need:
- Current GB coverage licences for the products you wish to access
- A licence for the service
- An API key which we will send you when you apply for a licence.
- Compliant GIS or a web browser
The API key is unique to your licence and you must therefore include it in any URL request or created code used to access the service. If you want to add more URLs to your API key, please contact us and we will register the new URLs against your API key.

Our WMTS can be accessed in the following ways. Click on the tabs below for details:

We will be adding alternative authentication methods such as http basic and IP ranges at a later date.
Please contact us should you wish to evaluate this method.
Mapping Layers and Look-ups
The following mapping layers are available through OnDemand WMTS. In order to achieve a friendly zoomed in/out effect, each product type has a suitable resolution measured in meters per pixel at which it should be viewed in a web application.
Each product type (except Overview maps) has been provided at two zoom levels or resolutions. When a product is Resampled it is twice the original resolution. 'R' denotes a resampled product.

*These do not form part of the Ordnance Survey product portfolio but are used to provide context at very small scales. No licensing restrictions apply.
** Look ups
There are two options for viewing the map content as a standard set of files or as a consistent seamless zoom stack. If you wish to get access to the full zoom map stack you will need to be licensed for GB coverage of our OSVectorMap Local product. Once this has been arranged, the layers will be made available. You will automatically get access to layers CS00 to CS08.
