Acknowledgements

This section is a guide to OS copyright acknowledgements (attribution statements) to be used by members and how they can be applied in different circumstances, but they are not exhaustive.

Members should note that it is still their responsibility to ensure that they are applying the terms of their Member Licence correctly.

There are four parts to this guidance about the use of acknowledgements:

General guidance

I understand we are a licensee of OS - what are our obligations?

When sharing OS information (including derived data), you must include an attribution statement; otherwise known as a copyright acknowledgement. 

The acknowledgement you use will depend on the type of OS data you are using and medium you are using (that is, paper, pdf, web mapping or data).

To save you the time of looking through the various sections of the Member Licence, we have provided the acknowledgements you need to use in the sections below.

We have also have provided Welsh language translations for those that need them.

Why do we need to add an acknowledgement?

Is to ensure that any recipient of information is made aware of the limitations of use.

It also helps us to know the source when investigating a potential infringement by a third party.

Do we need to acknowledge OS if we are publishing our own data?

If you have not used any OS data when creating the data, then we don't claim any intellectual property (IP) in it. The Member Licence defines this as independently sourced data.

If this is the only data being published, then you don't need to acknowledge OS.

If your data is included with OS data, then you should use the highest appropriate level of acknowledgement.

For example, if you are overlaying your non-OS based data on to OS VectorMap Local, then the acknowledgement to use is the Licensed data one.

Where and how must the acknowledgement(s) be shown?

You must clearly show it in a legible font and in a conspicuous position on reproductions of OS data, for example:

  • on a plot or view of data, 
  • the contents page of a book, 
  • the opening screen of a device, 
  • within terms and conditions of a service, 
  • as part of a 'read me' file when supplied as data.
For more information, see our Style Guide
Acknowledging OS OpenData (all forms of publishing)

This only applies when you are using OS OpenData products (including creating derived data from them). If Licensed Data is being incorporated, then you need to use the appropriate Licensed Data acknowledgement - and the OS OpenData acknowledgement is not required. 

We use the Open Government Licence (OGL) for OS OpenData. Under the terms of that licence, we are allowed to use our own attribution statement.

So, it doesn't matter whether the mapping is on paper or in digital form, if you are just publishing OS OpenData (or an 'exempted' dataset), you just need to include this attribution statement:

Contains OS data © Crown copyright [and database right] [year].

Welsh language version:

Cynnwys data OS Ⓗ Hawlfraint y Goron [a hawliau cronfa ddata] OS [flwyddyn].

Notes:

  • The same attribution acknowledgement should be included in any sub-licences of the data that you grant (or any other further re-use).
  • If you are using Code-Point Open you need to add an additional statement because that product contains additional 3rd party rights.
Are there other occasions when we can use the OS OpenData acknowledgement?

Yes.

You can use it with your derived datasets that have been notified to us under the 'presumption to publish' arrangements or where you been granted an exemption from the Member Licence

For more information on this see the derived data and derived data exemptions section.

Why is part of the acknowledgement in square brackets [ ]?

For example "Contains OS data © Crown copyright [and database rights][year]".

With [year], you insert the year that you are publishing the OS data.

With [and database rights], this statement is needed when you are publishing OS vector data, raster data stored in a database environment and addressing products. You can delete this statement on other occasions.

For example, if you are publishing OS Open Map - Local and or Boundary-Line data the acknowledgement is:

"Contains OS data © Crown copyright and database rights 2017"

Which OS data products don't need 'and database rights' included?

Our raster products, for example, 1:50 000 Scale Colour Raster and 1:25 000 Scale Raster.

All of our vector, addressing and Code-Point products need it included.

Note: If you are overlaying a raster layer with vector data, you need to include it.

Some acknowledgements contain 'EUL', what does this mean?

EUL means 'End User Licence'.

You should include EUL in the acknowledgement where an End User Licence is being used.

This will be where you are publishing Licenced data to a 3rd party, including where it being displayed on your website.

Note: you don't need to use an End User Licence in other circumstances.

More about publishing your information.

What if we are incorporating other OS data?

You need to use the highest appropriate level of acknowledgement.

As examples, you are:

  • combining OS OpenData with OS VectorMap Local, or
  • overlaying a derived dataset that has been granted an exemption on terms equivalent to OS OpenData onto OS MasterMap Topography Layer.

In both cases, the acknowledgement to use is the ‘Licensed data’ one and not the 'OS OpenData' one.

What acknowledgement is required for OS Licenced Data?

You need to use:

© Crown copyright [and database rights] [insert year] OS [licence number]

This needs to be shown in a legible font and in a conspicuous position

You may then need to add further information, depending on how you are publishing your information in (i.e. on paper, in electronic documents, on the web, or as a data file that can be used in a GIS).

Welsh language version:

Ⓗ Hawlfraint y Goron a hawliau cronfa ddata [mewnosod y flwyddyn] OS [rhif y drwydded]

Which OS data products have additional 3rd party licensing included?

They are:

PSMA / OSMA Licensed Data

  • All AddressBase products
  • Code-Point Open, Code-Point and Code-Point with polygons
Other OS products (for more information on these acknowledgements see our Style Guide). 
  • AddressBase Islands
  • Points of Interest
  • OS MasterMap Imagery Layer
What do we have to add when using an AddressBase product?

Whenever you are displaying or reproducing any AddressBase product, you need to include the following statement(s):

© Local Government Information House Limited copyright and database rights [year of supply or date of publication]

In addition, wherever data relating to Scotland is included, this statement also needs to be incorporated:

This product contains data created and maintained by Scottish Local Government

For example:

© Crown copyright and database rights (insert year) OS (licence number), © Local Government Information House Limited copyright and database rights and contains data created and maintained by Scottish Local Government [year of supply or date of publication].

Note: AddressBase products also includes AddressBase Incremental Change Supply (ABICS), which used to be known as the National Land and Property Gazetteer (NLPG) before it was rebranded.

Welsh language versions:

Ⓗ Hawlfraint a hawliau cronfa ddata cyfyngedig Tŷ Gwybodaeth ar Lywodraeth Leol [blwyddyn cyflenwi neu ddyddiad cyhoeddi]

and

Mae’r cynnyrch hwn yn cynnwys data a grëwyd ac a gynhelir gan Lywodraeth Leol yr Alban

What do we have to add when using a Code-Point product?

The Code-Point products are:

  • Code-Point Open
  • Code-Point
  • Code-Point with Polygons

You need to add the following statement to the base acknowledgement being used:

Contains National Statistics data © Crown copyright and database rights 20nn

For example:

© Crown copyright and database rights [insert year] OS [licence number] and contains National Statistics data © Crown copyright and database rights 20nn

Welsh language version:

Mae’n cynnwys data Ystadegau Cenedlaethol Ⓗ Hawlfraint y Goron a hawl cronfa ddata 20nn

Paper documents

What type of documents does this include?

We mean any document that includes a map, whether for internal or external use.

This includes, for example, map extracts, reports, information leaflets, decision notices, information/notice boards, etc.

What is the acknowledgement to use?

The standard acknowledgement to use on all map images:

© Crown copyright [and database rights] [year of supply] OS [licence number]. You are permitted to use this data solely to enable you to respond to, or interact with, the organisation that provided you with the data. You are not permitted to copy, sub-licence, distribute or sell any of this data to third parties in any form.

Welsh language version:

Ⓗ Hawlfraint y Goron [a hawliau cronfa ddata] [blwyddyn gyflenwi] OS [rhif y drwydded]. Rhoddir trwydded ddirymiadwy, anghyfyngedig a heb freindal i chi i weld y data trwyddedig at ddibenion anfasnachol am y cyfnod y mae ar gael gan [rhowch enw daliwr y drwydded] Ni chewch gopïo, is-drwyddedu, dosbarthu na gwerthu unrhyw ran o’r data hwn i drydydd partïon mewn unrhyw ffurf.

What if there is not enough room?

If your map image is A4 or less (and you can't add the standard acknowledgment) or you are only using a small extract of mapping, this is the next option.

© Crown copyright [and database rights] [year of supply] OS [licence number]

Welsh language version:

Ⓗ Hawlfraint y Goron [a hawliau cronfa ddata] [mewnosod y flwyddyn] OS [rhif y drwydded]

 

If that is still not achievable, the absolute minimum acknowledgement you can use is:

© Crown copyright

Welsh language version:

Ⓗ Hawlfraint y Goron 

However, we would only expect this absolute minimum acknowledgement to be used when the map extract in your document is less than A7 in size (approx 10cm x 7cm)).

Note: Depending upon the type of document, you should also endeavour to ensure that the full acknowledgement is included somewhere in a prominent position (i.e. perhaps along with other notices and acknowledgements).

What do we do when publishing several maps in the same document?

Wherever possible, you should always use the standard acknowledgement alongside each map. 

If that isn't possible, (for example, due to their small size), you can then just use '© Crown copyright' against each map image. 

You should ensure that the full acknowledgement is included somewhere in a prominent position (i.e. perhaps along with other notices and acknowledgements).

 

 

 

Electronic documents

What do you mean by electronic documents?

We mean any document that requires the use of a computer, tablet, smartphone or other device to view them; so this includes .pdfs and emails. 

What acknowledgement do we use in emails?

You follow the same guidance as if your map was being printed on paper

What acknowledgement do we use in pdf's?

The standard acknowledgement is:

© Crown copyright [and database rights] [year of supply] OS [licence number]. You are granted a non-exclusive, royalty free, revocable licence solely to view the Licensed Data for non-commercial purposes for the period during which [insert name of Licensee] makes it available. You are not permitted to copy, sub-license, distribute, sell or otherwise make available the Licensed Data to third parties in any form. Third party rights to enforce the terms of this licence shall be reserved to OS.

Welsh language version:

Ⓗ Hawlfraint y Goron [a hawliau cronfa ddata] Arolwg Ordnans [rhif y drwydded]. Rhoddir trwydded ddirymiadwy, anghyfyngedig a heb freindal i chi i weld y data trwyddedig at ddibenion anfasnachol am y cyfnod y mae ar gael gan [rhowch enw daliwr y drwydded]Ni chewch gopïo, is-drwyddedu, dosbarthu na gwerthu unrhyw ran o’r data hwn i drydydd partïon mewn unrhyw ffurf. Yr Arolwg Ordnans fydd yn cadw’r hawlio trydydd parti i orfodi amodau’r drwydded hon.

Is there an alternative way?

Yes, you could show the main acknowledgement and use a 'hyperlink' on the phrase ‘terms and conditions’ into another part of the document (which could be alongside any other required notices).

For example:

© Crown copyright [and database rights] [year of supply] OS [licence number]. Use of this data is subject to terms and conditions.

These are the conditions:

You are granted a non-exclusive, royalty free, revocable licence solely to view the Licensed Data for non-commercial purposes for the period during which [insert name of Licensee] makes it available. You are not permitted to copy, sub-license, distribute, sell or otherwise make available the Licensed Data to third parties in any form. Third party rights to enforce the terms of this licence shall be reserved to OS.

Welsh language version:

Ⓗ Hawlfraint y Goron [a hawliau cronfa ddata] Arolwg Ordnans [rhif y drwydded]. Defnyddio data hwn yn amodol ar delerau ac amodau.

Rhoddir trwydded ddirymiadwy, anghyfyngedig a heb freindal i chi i weld y data trwyddedig at ddibenion anfasnachol am y cyfnod y mae ar gael gan [rhowch enw daliwr y drwydded]Ni chewch gopïo, is-drwyddedu, dosbarthu na gwerthu unrhyw ran o’r data hwn i drydydd partïon mewn unrhyw ffurf. Yr Arolwg Ordnans fydd yn cadw’r hawlio trydydd parti i orfodi amodau’r drwydded hon.

What if we are publishing several maps in the pdf?

You follow the same guidance as though you were printing the document

 

Data

What do you mean by data?

We mean where you need to use a computer, tablet,  smartphone or other device to view the data. For example, within a GIS or displayed on a web page. This also includes data that you enable others to download for their use.

Note: if the information is a 'non-editable' table of attributes, then follow the same as though you were printing the document.

Web mapping - static images

The standard acknowledgement is:

© Crown copyright [and database rights] [year of supply] OS [licence number]. You are granted a non-exclusive, royalty free, revocable licence solely to view the Licensed Data for non-commercial purposes for the period during which [insert name of Licensee] makes it available. You are not permitted to copy, sub-license, distribute, sell or otherwise make available the Licensed Data to third parties in any form. Third party rights to enforce the terms of this licence shall be reserved to OS.

Welsh language version:

Yr Arolwg Ordnans fydd yn cadw’r hawlio trydydd parti i orfodi amodau’r drwydded hon.

Is there an alternative way?

Yes, you could show just the first sentence and then add some words that link to the 'terms and conditions' statement.

For example:

© Crown copyright [and database rights] [year of supply] OS [licence number]. Use of this data is subject to terms and conditions.

You could then 'hyperlink' the phrase ‘terms and conditions’  to either display them in a 'pop up' window, or to link to another web page (and which could include any other notices, acknowledgements, etc.).

These are the conditions:

You are granted a non-exclusive, royalty free, revocable licence solely to view the Licensed Data for non-commercial purposes for the period during which [insert name of Licensee] makes it available. You are not permitted to copy, sub-license, distribute, sell or otherwise make available the Licensed Data to third parties in any form. Third party rights to enforce the terms of this licence shall be reserved to OS.

Welsh language version:

Public web viewing of derived data to meet your INSPIRE obligations

You don't need to display a specific acknowledgement however, as part of the viewing service, you need to ensure that any recipient is aware of the terms of the INSPIRE End User Licence

Public viewing of data through web mapping services (non-INSPIRE)

The standard acknowledgement is:

© Crown copyright [and database rights] [year of supply] OS [licence number]. Use of this data is subject to terms and conditions.

The 'terms and conditions' you need to add are:

I. “You are granted a non-exclusive, royalty free revocable licence solely to view the licensed data for non-commercial purposes for the period during which [inset name of licensee] makes it available;

II. You are not permitted to copy, sub-license, distribute, sell or otherwise make available the Licensed Data to third parties in any form; and

III. Third party rights to enforce the terms of this licence shall be reserved to OS.”

Welsh language version:

Ⓗ Hawlfraint y Goron [a hawliau cronfa ddata] [blwyddyn o gyflenwad] Arolwg Ordnans [rhif y drwydded]. Defnyddio data hwn yn amodol ar delerau ac amodau.

II. Ni chewch gopïo, is-drwyddedu, dosbarthu na gwerthu unrhyw ran o’r data hwn i drydydd partïon mewn unrhyw ffurf; ac

III. Yr Arolwg Ordnans fydd yn cadw’r hawlio trydydd parti i orfodi amodau’r drwydded hon”.

How can I show this on a web page?

As for static images, you don't have to display the 'terms and conditions', instead you can 'hyperlink' the phrase ‘terms and conditions’  to either display them in a 'pop up' window, or to link to another web page (and which could include any other notices).

Alternatively, you can link that phrase to our Public Sector Viewing Terms web page.

Public viewing on of data in mobile applications

This includes the use of 'responsive' web pages (pages which automatically resize according to the device you are using).

Wherever possible, in the same way as other web publishing, you should use the same acknowledgement and terms and conditions statement on each page displaying mapping.

However, if there is insufficient room, you should display the full acknowledgement on your opening screen or on the general 'terms and conditions' page of the application being used.

 

Licensed Data supplied via download or on media

In addition to your use of a Contractor Licence or an End User Licence, this is the standard acknowledgement you need to include within the 'read me' file.

This means that you need to include 'EUL' as part of the acknowledgement - see below. 

© Crown copyright [and database rights] [year of supply] OS [licence number EUL]. You are permitted to use this data solely to enable you to respond to, or interact with, the organisation that provided you with the data. You are not permitted to copy, sub-licence, distribute or sell any of this data to third parties in any form.
