Ordnance Survey (OS) MasterMap (MM) is the premier digital product of the OS, the national mapping agency of Great Britain. It is a database that records every fixed feature of the land, manmade or physical, that is larger than a few metres in one continuous digital map. It is the most detailed and accurate digital map of Great Britain.
OS MasterMap can provide businesses with accurate location data that can help them solve various challenges, such as planning, development, risk assessment, asset management and more. In this blog post, we will introduce the main components of OS MasterMap and how to leverage them for your business needs using CentremapsLive, as a comprehensive mapping and data solution provider.

OS MasterMap Topography Layer
The OS MasterMap Topography Layer is the core component of OS MasterMap. It shows the shape, position, and attributes of more than 500 million real-world objects, such as roads, buildings, parks, and waterways. Each object has a unique identifier (TOID) that can be used to link it with other data source.
The OS MasterMap Topography Layer can help you:
Visualise and interpret your site or project in its geographic context
Geo-tag your assets and monitor their status and condition
Analyse the impact of environmental factors, such as flooding, pollution or noise
Enhance your map with additional layers of information, such as height data, tree data, aerial imagery or land registry data
You can access the OS MasterMap Topography Layer through CentremapsLive, either as a scaled print or image, or as a data export for your CAD or GIS system. You can also request complex areas or portfolios with the help of our support team.

OS MasterMap Sites Layer
The OS MasterMap Sites Layer is a complementary component of OS MasterMap. It shows the extents and access points of key locations, such as airports, schools, hospitals, utility, and more. It groups features into seven themes: air transport, education, medical care, rail transport, road transport, water transport, and utility or industrial. Each feature is available as three feature types: functional site, access point, and routing point.
The OS MasterMap Sites Layer can help you:
Identify and understand the wider geographic perspective of key locations
Find the most appropriate access points into a site for emergency or logistic purposes
Enhance your analytics and routing with site-specific information
Solve challenges such as how close a site is to something or what would be affected in an event
