OS MasterMap® is a comprehensive mapping database that contains a large number of different layers of information. It is created by the Ordnance Survey, the national mapping agency for the United Kingdom and it is one of the most comprehensive and detailed mapping databases in the world, covering all of Great Britain at a scale of 1:1250.
The exact number of layers of OS MasterMap® can vary depending on the specific version and release, but there are typically several hundred different layers of information available.
The exact number of layers can also depend on the specific application or use case. For example, some users may only need access to a subset of the available layers, while others may need access to the entire set of layers in order to perform more detailed analysis and mapping.
Regardless of the specific use case, OS MasterMap® is designed to provide a wide range of users with the information they need to make informed decisions about the physical features of Great Britain. Some of the users include government agencies, architects, surveyors, environmental agencies, tree specialists, various businesses, and individuals, that require accurate and up-to-date information about the United Kingdom's topography. The map is constantly updated with new information, so the number of available layers is subject to change over time.
