DHS Geospatial Data Model

Background

– Post September 11, 2001

• All levels of Government under increased pressure to overcome barriers to information sharing

– Geospatial information sharing no exception

– April 2006 DHS Geospatial Management Office (DHS GMO) launched

DHS Geospatial Data Model (DHS GDM) development

• In Enterprise Architecture terms, a LOGICAL Data Reference Model

• Version 1.1 released for review and comment June 2006

• Version 1.2 released for review and comment May 2007

3


DHS Goals

– Provide the homeland security community a foundational building block for geospatial interoperability and information sharing

• Non-FOUO

– Provide the GIS vendor community a logical data model from which to implement PHYSICAL data models

• Oracle Spatial

• ESRI Geodatabase

• Others

– Provide the homeland security partnership community a logical data model from which to implement PHYSICAL data models

• Geospatial information sharing add-ons to existing business systems

• New starts

4


DHS Goals

– Significantly enhance the National Information Exchange Model (NIEM) through development of the NIEM Geospatial Insertion Package (DHS GDM)

• NIEM complies with the Homeland Security Presidential Directive-5 (HSPD-5)

– HSPD-5 assigns DHS Secretary role of principal federal official for domestic incident management

– Establish a baseline for implementation by DHS Components and Agencies

• Supports DHS move toward Geospatial Services Oriented Architecture

• Baseline reference for a geospatial metadata registry

• Template for sharing geospatial datasets

• Cost-reduction driver to eliminate duplication

• Standardized acquisitions & outsourcing template

• Template for common operating views & standard briefing presentations

• Feb 2008+

5


DHS Goals

– Encourage homeland security partners to use the DHS GDM

• Source to understand the data needs and content of interest to homeland security community

– Data collection

• Data sharing

– Data exchange through extract, transform and load– Web services (WMS, WFS, …)

• Grant guidance

– Gain non-mandatory FGDC recognition of the DHS GDM

• Engage FGDC Homeland Security Working Group for public vetting

• Strengthen the model through empirical development

6


General Approach to Data Model Construction

– At all times, use National standards-based data constructs over proprietary constructs

• Follow Universal Modeling Language (UML) practices in the FGDC Framework Standard

• Follow ISO 19103 (Conceptual Schema Language) guidelines

• Follow FGDC guidance to build logical models with a “package of packages” hierarchical structure

– Generate and share associated documentation

• UML model

• Data dictionary following FGDC guidance and ISO 11179-3

• Model description document

7


Data Content - Version 1.1 (June 2006)

– NIEM geospatial data types

• Starting point, joint DHS and DOJ logical data model content

– FGDC “Framework” model to describe the core data layers

• Cadastral, Orthoimagery, Elevation, Geodetic Control, Governmental Units, Hydrology, Transportation

– “Project Bluebook” model for structures and critical infrastructure

• Key layers not in FGDC & NIEM models

• UML from ESRI

8


Data Content - Version 1.2 (May 2007)

– Many improvements via public comments• NSGIC Recommended Data Types (Hurricane Katrina Experiences)

• Additional NIEM Data Types

– Core Types, Attributes for all Mission Domains– Emergency Management and Infrastructure Protection Types– External Authority Code Lists

• FEMA Multi-Hazard Model Data Types

• Geographic Names Information System (GNIS) Feature IDs and types

• Feature types for FGDC Emergency Management Symbology

• National Incident Management System (NIMS) Resource types

• National Hydrography Dataset (NHD) Feature Types

• Revised Cadastral Model from FGDC Cadastral Subcommittee

• National Response Plan Categories

• Homeland Security Infrastructure Protection (HSIP) Feature Types

• Land Cover Classification from NASA

• Land Use Classification from American Planning Association (APA)

• FGDC and ISO Geospatial Metadata

FGDC HSWG Facilitation

– HSWG Content Subgroup re-chartered to coordinate DHS GDM public comment adjudication

– Established website for download of data model documentation• www.fgdc.gov/dhsgdm

– Developed a comment resolution matrix (MS Excel spreadsheet)

– Solicited public comments, posted matrix to FGDC website• Version 1.1 - 131 comments received

– Coordinated comment adjudication meetings with DHS Modeling Team– 103 comments resolved – 28 comments unresolved

• Version 1.2 - additional 92 comments received (+ 28 v1.1 unresolved = 120)

– Comment resolution with DHS Modeling Team resumes Oct 2-3

– NSGIC participation• Bill Burgess, John Gottsegan, Mike Mahaffie, Chris Welchhans, Michael Ouimet

10


DHS GMO Modeling Team

– SAIC, Image Matters LLC• NIEM expertise • Extensive harmonization effort across UML sources• Incorporation of adjudicated public comments

– DHS GDM version 1.1 documentation• 403 page PDF, intended for modeling professionals

– DHS GDM version 1.2• Improved documentation and tools• Increased use of FGDC website• Modeling professionals remain primary audience
