OS MasterMap Sites Layer

Functional Sites are made up of a polygon (object) representing the area, or extent, of the function or activity, with appropriate attribution. It gives information surrounding the functional theme of the site (for example, education), specific site function (for example, primary education), site name, site size, Unique Property Reference Number (UPRN) and additional supporting attribution (for example, version date). It also includes whether the site is operational or not and all the buildings and land within the site.

Including the primary UPRN of the site enables linking of the site to our address suite of products. The product makes it easy to see the area of a site, for example a school, or a hospital, covers.

 _{(Unique Property Reference Numbers (UPRN) are unique numeric identifiers for every spatial address in Great Britain as assigned by Local Government address custodians.)} 

An access point is a point feature type that refers to the accepted and maintained locations where pedestrians and/or vehicles can enter or leave a site. It gives information associated with access type (for example, pedestrian), contains attribution that allows interoperability with other feature types (for example, reference to the OSMM Highways Network) and additional supporting attribution (for example, version date).

Access points makes the creation of routes to sites much more accurate. It can be used to help calculate routes to schools, (walking or vehicular) and emergency access to sites.

Access points are captured and maintained from either a visual inspection of OS MasterMap Topography Layer and Imagery Layer or through field survey. Each Access point feature is positioned on the boundary of the functional site. However, there are possible circumstances where access points do not lie on the site boundary. For example, underground access into a site, and these would be captured in either their true position or within a metre of the functional site extent boundary.

This image shows Motor Vehicle access points.

The image shows Motor Vehicles and Pedestrian access for sites with OS Maps API as a backdrop with the light styling. These points could be used for active travel planning as they help in multi modal routing by creating links between different transport types, e.g. from road to rail or air transport.

This image shows an individual Air Transport site -London City Airport

And with the attributes for Air Transport added for the London City Airport.

Education

This theme includes a very broad group of sites with a common high-level primary function of providing education (either state-funded or fee paying).

The types of educational establishments include Further Education, Higher Education, University, Non State Primary or Preparatory School, Non State Secondary School, First School, Infant School and Junior School, Middle School, Primary School, Secondary School and Special needs Education.

The image shows an education site against the OS Maps API as a backdrop.

This image includes the attributes for Education. The type of education establishment is shown which in this case is a Primary School. It shows the school is operational and that the name of the school - Drew Primary.

Medical Care

This theme includes sites that focus on the provision of secondary medical care services. Which are shown overlaid on the OS Maps API.

Examples include: hospice, hospital and medical care accommodation.

This image shows a Medical Care site against the OS Maps API.

The following features are included in the captured extent:

• main buildings;

• site-specific service buildings and structures;

• access roads and paths;

• site-specific car parks; and

• areas of man-made and natural surface surrounded by included areas.

This image shows the attributes for a Medical Care Site, in this case a Hospice. It's functional status shows it to be operational and gives the name of the Hospice as Richard House Children's Hospice.

Rail Transport

This theme includes sites associated with the movement of passengers and goods by rail.

Examples are: railway stations, vehicular rail terminals and tram stations.

This image shows a Rail Transport site against the OS Maps API.

The following features are included in the captured extent:

• station buildings;

• station shelters;

• platform areas;

• access roads and paths;

• station footbridges and associated structures;

• station car parks;

• areas of man-made and natural surface surrounded by included areas;

• areas of man-made and natural surface abutting included areas along a non-obstructing edge.

This image shows the attributes for a Rail Transport Site. It shows that the site is a Railway Station and is the Custom House Station for ExCel.

Road Transport

This theme includes sites associated with the movement of passengers and goods by road.

Examples are: bus stations, coach stations and road user services.

This image shows the Road Transport site against the OS Maps API.

The following features are included in the captured extent:

• bus/coach station buildings (for example, ticket office or waiting room)

• bus/coach station shelters;

• car/bus/coach parking areas;

• buildings for bus/coach storage, maintenance and cleaning;

• access roads and paths;

• areas of man-made and natural surface.

This image shows the attributes, which includes it's status, in this case it is operational, the type of site, a Bus Station, and its name Prince Regent Bus Station.

Utility or industrial

This theme includes sites where the following activities take place:

Where energy (that is, electricity, gas or oil) is produced, refined, distributed or stored.

Sties where the principles of chemistry are applied to materials to create different materials on a large scale.

As an example the image shows an Oil Distribution or Storage site.

The following features are included in the captured extent:

• internal site access roads and paths;

• buildings and structures associated with the operation of the site;

• areas of man-made and natural surface totally surrounded by included areas;

• areas of man-made and natural surface abutting included areas along a non-obstructing edge;

• for marine oil terminals, related berthing structures physically connected to the site are included.

The attribution for Manhatten Wharf is displayed in the image. The attribution shows the function of the site which is Oil Distribution or Storage and it is operational.

Water Transport

This theme includes sites that are involved in the transfer of passengers or goods onto vessels for transport across water.

Examples include vehicular ferry and passenger ferry terminals.

This image shows a Water Transport site against the OS Maps API.

The following features are included in the captured extent:

• port buildings (for example, customs office, ticket office, waiting room);

• vehicle parking/waiting areas;

• structures for loading people, vehicles or goods onto vessels;

• access roads and paths; and

• areas of man-made and natural surface surrounded by included areas.
