DHS weaves geospatial data into its enterprise architecture

The Homeland Security Department plans to control its geospatial data through its enterprise architecture.

The Geospatial Information Office in the agency's CIO office has developed an enterprise architecture view for each of the four layers of the modernization blueprint'business, application, data and technology.

Ryan Cast, the department's geospatial information officer, said an interagency task force with representatives of the Interior and Defense departments as well as the National Geospatial-Intelligence Agency determined how geospatial information applies to each layer of the architecture.

'We were able to identify 67 out of 77 homeland security business activities that have a geospatial context,' Cast said. 'The DHS EA team will integrate our information into the overall architecture.'

Cast said geospatial information is a crucial factor in the mission of identifying homeland security threats. With geospatial data woven into the EA, the IT investment review team can see how all the information fits together.

Cast said the EA team is working with the Federal Enterprise Architecture Program Management Office to decide how the agency's data matches the federal architecture.
