The Department of Homeland Security (DHS), Office of the Chief Information Officer (OCIO),
Geospatial Management Office (GMO) has developed this DHS Geospatial Data Model
(DHS GDM) in support of urgent DHS mission requirements. This DHS GDM is a standards based, logical data model to be used for collection, discovery, storage, and sharing of homeland
security geospatial data. The model will support development of the Department’s services-based
geospatial architecture, and will serve as an extract, transform, and load (ETL) template for
content aggregation.
