Geospatial Data Model Version 2.7

Version 2.7, released in February 2009, has been updated and harmonized with a number of additional models to fully incorporate key homeland security initiatives.  The GMO team integrated the Fire/Hazmat data model developed in partnership with the National Association of State Fire Marshals and the Metropolitan Fire Chiefs, a member organization of both the National Fire Protection Association (NFPA) and the International Association Fire Chiefs (IAFC).  Another key component of this version change was to update the model with the latest Infrastructure Taxonomy, Version 3.0.  Finally, the GDM now incorporates HSIP Gold Version 2008 in the model, integrating all the new and updated feature classes, definitions and component parts.  Version 2.7 is now available for download in the following formats:


As in previous versions, the FGDC Homeland Security Working Group and the GMO are extremely interested in soliciting user feedback about the models and ways to make it more accessible by all users.
