April 2024

OS Open Greenspace depicts the location and extent of spaces, such as parks and sports facilities, which are likely to be accessible to the public. Where appropriate, it also includes access points to show how to get into these sites. Its primary purpose is to enable members of the public to find and access greenspaces near them for exercise and recreation.

Product issues and enhancements

Quality

There are no significant issues that would impair the use of this product in the April 2024 release. However, there are two error types that have been identified with this release that users should be aware of:

1. The product contains 19 841 sites that do not have any Access Points. This is due to the constraints of capturing the sites via aerial imagery (for example, some Access Points may be obscured by tree canopy) and / or because a site may lack definitive Access Points (for example, a playing field with no bounding fence or hedgerow). Ordnance Survey aims to reduce the number of sites with missing Access Points as part of ongoing continuous improvement processes.

2. The product contains 73 instances of duplicate sites (geometry) in the same tile. These errors appear to be caused by the automated production process. Ordnance Survey aims to reduce the number of duplicate sites as part of ongoing continuous improvement processes.
