This release note provides information about the April 2024 release of OS MasterMap Sites Layer.

OS MasterMap Sites Layer provides a nationally consistent representation of polygon features that represent the area or extent of certain types of function or activity with the appropriate attribution. The product also includes access points to assist in navigating into and out of the sites (with references to OS MasterMap Highways Network – Roads product).
| Feature Type | Previous Release Count (October 2023) | New Release Count (April 2024) |
|---|---|---|
There are no significant issues that would impair the use of this product in the April 2024 release. However, there is one minor error identified with this release that users should be aware of:
1. There are 26 instances of Access Point features not intersecting the edge of the associated Functional Site, whereby the Access Point geometry is between 5 and 100m in distance from the referenced Functional Site.
* Routing Points are no longer supplied from October 2023 release onwards (see Product Improvements section)
To meet customer needs, Ordnance Survey has created a fully routable multi-modal network, and a key element of this is to provide more usable data about the access to destinations. To this end, we are now directly splitting our road, track and path data where Access Link features connect to the network; this will allow customers to more easily route into sites using OS network data.
Whereas previously some Access Points referenced Routing Points, all will now reference a Road Node from OS MasterMap Highways Network – Roads product. Consequently, there is no requirement for Routing Point features, and these features are no longer suppled as part of OS MasterMap Sites Layer.
As a result, no Routing Point layer has been supplied from the October 2023 publication onwards.
For customers that use GML format, there is no change to the schema so product loading should be unaffected. However please be aware that for customers using GeoPackage no table for Routing Points is provided and similarly for vector tile format no layer for Routing Points is provided.
The next release of OS MasterMap Sites Layer is scheduled for October 2024.
