The use of independently sourced data with Ordnance Survey data

Put simply, we don’t claim intellectual property rights (IPR) in data that has been created independently of Ordnance Survey data and then used with it. 

In practice this means that: 

• If data is created by means of an independent survey and then displayed with an Ordnance Survey mapping backdrop, we claim no ownership of that data. It is not, therefore, subject to any of our licensing terms.
• If data is created as described above and then overlaid onto Ordnance Survey licensed data for the purpose of verification, we claim no ownership of that data unless features are repositioned as a result. If a feature is repositioned, then our IPR will be present in it. In these circumstances the data will be subject to the licensing terms applicable to the Ordnance Survey source data used.
• If additional independently sourced descriptive information or atribution is attached to Ordnance Survey licensed data, we claim no ownership of that additional information. It is not, therefore, subject to any Ordnance Survey licensing terms.

Examples of data that has been created independently of Ordnance Survey data and then used with it:

• Mapping fire hydrants 
• Adding bus stops 

Ordnance Survey claims no ownership of this data. It is important to note, however, that if Ordnance Survey licensed data is used as a backdrop, an appropriate licence will still be required.
