Ordnance Survey – Great Britain's national mapping agency
The OS OpenSpace service is free of charge and enables web applications to be built using datasets that are hosted by Ordnance Survey. The web-map builder application simplifies the process so that no specific technical knowledge is required.
OS OpenSpace was designed to promote experimentation with Ordnance Survey datasets. It is available for use by anyone – including commercial organisations – and enables web applications with a wide variety of functionality to be created. Advertising is permitted (with certain exceptions) and donations can be solicited for non-profit making, community or volunteer groups.
When considering the suitability of OS OpenSpace for your proposed use, you may wish to note that OS OpenSpace applications must be publicly accessible and not used for the internal administration of a business. Ordnance Survey data cannot be downloaded or archived and no charge may be made to access it.

Users of your web application may also post their data on to it.
In simple terms, therefore, you can:
