UK Office of the Deputy Prime Minister: Maps on Tap
The service has been developed to provide government and citizens with easy access to quality-managed information about places. Access to the overall service is free but access to some applications may be limited by licensing restrictions.
Users can select from over 200 sources of information in map form (with charting and tabular formatted data to be provided at a later date). UK Government organisations can enhance their own web services with map content and information from the Maps on Tap service.
