The Geographical Information Systems (GIS) team manages the provision of all geospatially referenced mapping data to the project. This includes the provision of mapping data to a number of other functions within the business such as CAD, Delivery and Land and Property, and also includes presentation of data through an organisation wide portal to allow all stakeholders to view geospatial information within a single interface.

In addition to feeding mapping data to the project, the GIS team also take data feeds from within the project, allowing greater visualisation and analysis of different aspects of the project, including Engineering, Land and Property, Asset and Utilities information which helps make better informed decisions during design and construction.

In order to achieve this state, a Spatial Data Infrastructure has been constructed to ensure that information is discoverable, accessible and accurate.  Once this was in place it enabled the direct assimilation of business data, including workflows for managing land and property information, into a common data environment from which content can be published. The common data environment has also allowed Crossrail to make the information accessible through the enablement of mobile mapping for Land Management.
