GMO Geospatial Enterprise Data Modeling2 Outline Business Requirements Technical Approach Modeling Considerations Task Description Vetting Process Proposed Schedule Group Discussion

GMO Geospatial Enterprise Data Modeling3 Business Requirements Support DHS Business Missions Enable Data Exchange among DHS Components Enable ETL Processes with States & Locals Comply with FGDC Standards and Guidelines Align with FEA Geospatial Profile Align with DHS Enterprise Architecture (EA) Align with DHS Geospatial Enterprise Architecture (GEA) Align with DHS Geospatial Data Warehousing Strategy Be Public Accessible (Not FOUO) Leverage Existing Data Models Have Sufficient Documentation for Future Implementation

GMO Geospatial Enterprise Data Modeling4 Technical Approach Start with ESRI Bluebook Data Model Use FGDC Framework Model to Describe 7 Framework Data Layers:  Cadastral data describe the geographic extent of past, current, and future right, title, and interest in real property, including above, surface, and below ground and water, and the conceptual structure to support the description of that geographic extent  Digital Orthoimages are georeferenced images of the Earth's surface for which image object displacement caused by sensor orientation, sensor distortions, and terrain relief has been removed.  Elevation data may be modeled in various forms, such as in an evenly spaced grid or as irregularly spaced points (triangulated irregular network, hypsography, or mass points).  Geodetic control provides a common, consistent, and accurate reference system for establishing coordinates for all geographic data.  Governmental Unit Boundaries and other geographic area boundaries establishes the content requirements for the collection and interchange of governmental unit and other legal entity boundary data to facilitate the maintenance and use of that information.  Hydrology includes surface water features such as lakes, ponds, streams or rivers, canals, oceans, and shorelines.  Transportation data are used to model the geographic locations, interconnectedness, and characteristics of the transportation system.

GMO Geospatial Enterprise Data Modeling5 Technical Approach Use NIEM/URISA Address Data Model to Describe Addresses and Names Use NIEM/EDXL Data Model to Describe Emergency Operations Leverage HSIP/NADB/NIEM Data Model to Describe Structure and Critical Infrastructure Adopt the Bluebook Data Model (assuming it is latest and greatest from ESRI) for the rest of the Relevant Data Layers

GMO Geospatial Enterprise Data Modeling6 Modeling Considerations Select National Standard-based Data Constructs over Proprietary Data Constructs Select Semantic Rich Data Constructs (see examples) Use UML (Unified Modeling Language) for Logical Model  FGDC Guideline: “The use of UML class diagrams is an application-neutral approach to depict the inherent description of and relationships among data entities. These diagrams should neither be interpreted as requiring object-oriented implementation – methods or interfaces are not typically shown on these data classes – nor should they be interpreted as representing tables in relational databases. Instead, the UML classes should be used as the basis for translation to and from internal organization data stores and applications. UML modeling environments typically support conversion of logical UML models into implementations in various programming environments through rule-based transforms.” Each of the FGDC Framework schema expressed in the Unified Modeling Language (UML) according to ISO 19109, Geographic information – Rules for application schema, and its normative references. The application schema specifies, as appropriate, the feature types, attribute types, attribute domain, feature relationships, spatial representation, data organization, and metadata that define the information content of a dataset.  Follow UML Practices in the FGDC Framework Standard, e.g. use > as an semantic extension mechanism for existing UML concepts.  Follow Guideline of ISO (Conceptual Schema Language) ISO provides rules and guidelines for the use of a conceptual schema language. The chosen conceptual schema language is the Unified Modeling Language (UML). It provides a profile of UML for use with geographic information. In addition, it provides guidelines on how UML should be used to create standardized geographic information and service models.  The Logical Model has a package of packages hierarchical structure following FGDC practice.

GMO Geospatial Enterprise Data Modeling10 Vetting Process The Data Model will be vetted through FGDC HSWG Info Content Sub-Group The Data Model will be Recommended to FGDC HSWG for Draft Endorsement

GMO Geospatial Enterprise Data Modeling11 Vetting Process FGDC HSWG Info Content Sub-Group needs to establish a checklist of expected content and document any perceived discrepancies 1. Parcel Boundaries 2. Road Centerlines with Address Ranges 3. Water Supply/Storage/Treatment Facilities/Lines 4. Water Bottling Locations 5. Wastewater Facilities/Collection Areas/Collection Lines 6. Oil Storage Facilities and Retailers Including Gasoline (required for two reasons - shortage issues and pollution issues) 7. Telecommunication Service Areas, Facilities, and Towers (Land Line and Cell Phone) 8. Imagery 9. Power Plants/Service Provider Areas/Electric Grid/Transmission Lines 10. Natural Gas Plants/Service Provider Areas/Transmission Lines 11. Telecommunication Provider Service Areas (both land line and cell phone) 12. Banks and Financial Institutions 13. Bus Transport Companies 14. Storm water Drainage Lines and Pumping Stations 15. Topography 16. Common USAR Grid 17. Hospitals/Walk-in clinics/In-patient Residential Facilities w/Emergency Contact Information 18. EMS 19. Police 20. Fire & Rescue 21. Response Team Staging Areas (e.g. USAR) 22. Shelter/Victim Relocation Areas 23. Intersection Points (with Lat/Long coordinates) 24. Neighborhoods/Subdivisions/Parishes/Districts
