- 28. Survey and MappingOffice Lands Department 28 Data as Infrastructure Data informs how infrastructure is built, managed and eventually decommissioned, and real-time data can inform how infrastructure is operated on a second-to- second basis. Data is now as much a critical component of infrastructure as steel, bricks and mortar. Data is part of infrastructure and needs maintenance in the same way that physical infrastructure needs maintenance Source: National Infrastructure Commission, British Data creates value: leveraging data to get more out of infrastructure
