How to get OS mapping data

Check if your organisation is a member of a mapping agreement

Use our find a public sector member map to see if your organisation already belongs an OS mapping agreement. There are two mapping agreements: the Public Sector Mapping Agreement (PSMA) and the One Scotland Mapping Agreement (OSMA).

Alternatively, download our list of PSMA and OSMA member organisations (XLSX format or CSV format), last updated 31 October 2018. In Excel or equivalent, speed up your search using the Find in file tool (Ctrl + F5).

If your organisation is listed, please talk to your principal OS contact about your data needs. If you don't know who this is, contact us and we'll pass on your details.

If you're not already a member, sign up to a mapping agreement

Having the latest geospatial data at your fingertips can help you make better decisions and boost efficiency in your organisation.

Because we're a government-owned organisation, all levels of public sector organisations have access to an OS mapping agreement which provides a hugely valuable service. This means you can use OS resources free of charge.

There are two mapping agreements:

Public Sector Mapping Agreement (PSMA)

This is for organisations in England and Wales.

One Scotland Mapping Agreement (OSMA)

This is for organisations in Scotland.

Not a member?

Use our find a member map to check if your public sector organisation is already signed up to the PSMA or OSMA.

If you're not yet a member and would like to join a mapping agreement, sign up now for free.

Licensing and sharing OS data

Once you’re a PSMA or OSMA member you're licensed to share OS data with other people and organisations. For example MPs, councillors, contractors, schools and community groups.

Releasing data derived from OS maps with confidence

Use a Geographic Information System (GIS)

If you don’t have one already, you’ll need a GIS to view OS data. A GIS lets you analyse OS data together with your own and third party data.
