OS MasterMap Sites Layer Getting Started Guide
This getting started guide provides instructions for using OS MasterMap Sites Layer in different software applications. Users with limited technical knowledge will be able to follow this guide.
This getting started guide shows you how to load the GML supply of the OS MasterMap Sites Layer into several commonly used geographical information system (GIS) applications.
Product supply and formats
OS MasterMap Sites Layer is supplied as an online download in the OS Data Hub.
You can order OS MasterMap Sites Layer data for either all of Great Britain or by 5 km² tile. In the 5 km² tiles, features are not clipped at tile edges, resulting in what is known as 'hairy' tiles.
The product is available in the following formats:
GeoPackage
Vector tiles (MBTiles)
GML (3.2.1)
All formats contain three layers: Functional Site, Access Point, and Routing Point.
File naming conventions
The GML file naming conventions for OS MasterMap Sites Layer are:
National sets
National datasets are grouped into the seven themes within Sites Layer: air transport, education, medical care, rail transport, road transport, water transport, and utility and industrial.
File names follow this pattern: <product>_<theme>_<area>.gz, for example, osmmsites_airt_england.gz.
Tiled data
Tiled datasets are provided in 5 km² tiles. Each tile includes all themes present in that tile. Files names follow this pattern: <5k tile ID>.gz, for example, HP5000.gz.
