OS Open Map – Local (OML) is an open dataset of detailed, street-level mapping of Great Britain. OML provides one of the most detailed generalised open mapping products available and is designed to provide contextual mapping for your applications or web pages. It offers users a clear contextual view of the world whilst also enabling the undertaking of analytical activities.
This product is updated every six months in April and October.
OS OML can support a wide range of customer applications that utilise geographic information. The product is ideal for providing backdrop mapping on websites and displaying business locations on small-scale 'street level' maps.
Quickly identify hotspots in data like crime location or property prices. The muted colours of this detailed backdrop map let your information really stand out.
Get greater insights into land use for local planning. OS OpenMap - Local doesn't just pinpoint schools, hospital and other major facilities, it maps the grounds they occupy.
OS OpenMap – Local includes a raster image option, carefully styled according to customer feedback. This is easy to load in a GIS and lets you start analysing data quicker.
To help you navigate around Britain, we’re adding more names, such as those of isolated homes and farms, and roads, both public and private. This detail comes into its own in rural and suburban areas.
