Official Ordnance Survey polygons showing Borough boundaries and reference code to link to national statistics.2018. Data is an extract from Ordnance Survey Boundary-Line product which is a specialist 1:10 000 scale boundaries dataset. It contains all levels of electoral and administrative boundaries, from district, wards and civil parishes (or communities) up to parliamentary, assembly and European constituencies. The information is represented as vector digital data. The boundary information is updated twice a year, in May and October. The May release contains the boundaries that have become live in the first week of May, in the year of release. The October release contains the May boundaries plus additional information.

London’s first Cultural Infrastructure Map brings together new research and information that has previously not existed in one place. It plots the location of cultural infrastructure and enables the user to view it alongside useful contextual data.

This page contains cultural infrastructure data sets collected from summer 2024 to summer 2025 and published in 2024 and 2025. Data sets are uploaded as they become available over this period.

Audits of facilities or infrastructure are a snapshot in time and based on best available information. We welcome contributions or updates to the datasets from Londoners and others which can be submitted through the Cultural Infrastructure Map .

Data and analysis from GLA GIS Team form a basis for the policy and investment decisions facing the Mayor of London and the GLA group. GLA Intelligence uses a wide range of information and data sourced from third party suppliers within its analysis and reports. GLA Intelligence cannot be held responsible for the accuracy or timeliness of this information and data.

The 2011 Census output area boundaries were released by ONS on 30 October 2012. The ONS release constituted a single dataset covering the entirety of England and Wales.

The GLA has extracted the boundaries for each London borough and provides them here in MapInfo (.tab) and ESRI ArcGIS (.shp) file formats.

Included are Output Area (OA), Lower Super Output Area (LSOA) and Middle-Level Super Output Area (MSOA) bounadries.

Each geography is provided at Extent of the Realm (BFE), Coastline (BFC) and Generalised Coastline (BGC).

More details about 2011 Census geography can be found on the ONS website: http://www.ons.gov.uk/ons/guide-method/geography/products/census/index.html

Transport for London's (TFL) Public Transport Accessibility Levels (PTALs)

PTALS are a detailed and accurate measure of the accessibility of a point to the public transport network, taking into account walk access time and service availability. The method is essentially a way of measuring the density of the public transport network at any location within Greater London.

Each ares is graded between 0 and 6b, where a score of 0 is very poor access to public transport, and 6b is excellent access to public transport.

The current methodology was developed in 1992, by the London Borough of Hammersmith and Fulham. The model has been thoroughly reviewed and tested, and has been agreed by the London Borough-led PTAL development group as the most appropriate for use across London.

The measure therefore reflects:

• • Walking time from the point-of interest to the public transport access points;
• • The reliability of the service modes available;
• • The number of services available within the catchment; and
• • The level of service at the public transport access points - i.e. average waiting time.

It does not consider:

• • The speed or utility of accessible services;
• • Crowding, including the ability to board services; or,
• • Ease of interchange.

The PTAL methodology was developed for London where a dense integrated public transport network means that nearly all destinations can be reached within a reasonable amount of time. Research using the ATOS (Access to Opportunities and Services) methodology shows that there is a strong correlation between PTALs and the time taken to reach key services – i.e. high PTAL areas generally have good access to services and low PTAL areas have poor access to services.

Notes

6-digit references identify 100m grid squares.

The 2012 CSV file previously available on the Datastore is now only available via the TfL feeds page.

The 2014 files are available to download below. This includes the GIS contour files.

Current PTAL values can be viewed at TfL’s web site: www.webptals.org.uk

The GLA has calculated the percentage of population for each ward, LSOA, MSOA and borough within each PTAL. The files for 2014 are available below. The method used mapped the number of addresses (using Ordinance Survey AddressBase Plus, and 2011 Census London Output Areas boundaries).

TFL also publish on their website a tool that shows travel time and PTAL maps from any point within London. Click anywhere on the map or input a postcode to change the selected location.
