To ensure safety and security during the 2012 London Olympics Games, the Metropolitan Police service needed a single, definitive and easy-to-use way to securely view and share mapping, and associated data. During the Games, this new mapping portal was used by more than 2,000 users within the Metropolitan Police. In addition, more than 46 external agencies also had access to the system.
The Department for Business, Innovation and Skills intends to reduce the number of premises used by BIS from around 200 to between 50 and 70. Geographic information supplied through the Public Sector Mapping Agreement has played an important role in the programme’s success to date.
