1 U.S. National Spatial Data Infrastructure Douglas Nebert FGDC/GSDI Secretariat

2 FGDC Federal Geographic Data Committee Foundation of US NSDI NSDI established as initiative under the interagency coordinating committee, the Federal Geographic Data Committee (FGDC) FGDC has 17 member federal organizations, official liaison with 35 state councils, and other sectoral organizations Executive Order 12906 (1994) compelled federal government participation in NSDI

3 FGDC Federal Geographic Data Committee Participation in NSDI through FGDC US Federal Government agencies (17) 35 state geo-information councils National States Geographic Info Council National Association of Counties National League of Cities Universities (UCGIS) Vendor community: OpenGIS Consortium

4 FGDC Federal Geographic Data Committee Standards Clearinghouse Metadata Framework Working Groups Organization of FGDC Steering Committee Coordination Group Secretariat Staff TransportationWaterElevationOrthoimageryCadastreGeodeticGovernmental UnitsGeologyVegetation... Thematic Subcommittees

5 FGDC Federal Geographic Data Committee Legal Framework FGDC constituted through the Executive Branch, Office of Management and Budget (OMB) Circular A-67 for interagency coordination on geographic information Only federal members permitted to vote on adoption of FGDC standards and policies, but process open to all FGDC encourages standards and specification development in ISO, ANSI, and OGC by all NSDI participants

6 FGDC Federal Geographic Data Committee Roles and Responsibilities FGDC Secretariat: staff of ~15, provides forum for policies and standards that integrate into a coherent NSDI Steering Committee: staffed by agency managers, meets 2-3 times per year, approval of policies and FGDC Standards Coordination Group: chairs of all WGs and Thematic Subcommittees and agency reps, meets monthly WG and TS members: volunteer domain experts

7 FGDC Federal Geographic Data Committee NSDI Funding Annual allocation to FGDC Secretariat of approximately $3.6M Cooperative Agreements Program allots between $1-2M per year from this for sustainable NSDI- building projects FGDC budget covers Secretariat expenses, interagency projects, and common-use infrastructure maintenance FGDC member organizations invest at least as much in SDI operations

8 FGDC Federal Geographic Data Committee Standards OMB Circular 119 requires governmental bodies to work first through international and national standards bodies before developing government-specific standards FGDC participates in US National Standards for geomatics (ANSI INCITS-L1) and as part of US delegation to ISO TC 211 Data content standards and the Metadata Standard were developed through FGDC – will be migrating this process under ANSI

9 FGDC Federal Geographic Data Committee NSDI and Standards Advocacy OpenGIS Consortium, W3C Software interfaces (Implementation Specifications) ISO TC 211 Foundations for implementation. (Abstract standards) NationalStandards Content standards, Authority for data Endorsed practices and specification s NSDI Other NSDIs Regional SDI Coordination

10 FGDC Federal Geographic Data Committee Intellectual Property Rights/Pricing NSDI founded on principle of “freedom of discovery” to promote awareness and access to all geo-information Encourage the publication of ALL metadata for data for free or for a fee with the metadata declaring access characteristics and asserter property rights Federal agencies must make all non-sensitive data available only at the cost of dissemination, but no standard fee schedule exists (per OMB A-130)

11 FGDC Federal Geographic Data Committee Educational Aspects FGDC has published educational materials and reference implementations of software to promote competence in NSDI concepts FGDC underwrites local, regional, and national training opportunities through a cadre of on-call trainers Research grants provided to University Consortium for Geo Information Sciences (UCGIS) for NSDI curricula and evaluation

12 FGDC Federal Geographic Data Committee Content: Core Data Core data are known as Framework and represent the most commonly used data in base mapping, collected by various agencies: – Elevation – Hydrography (Surface Water) – Governmental Units (Boundaries) – Orthoimagery – Transportation (multi-modal) – Cadastre – Geodetic Control

13 FGDC Federal Geographic Data Committee Framework Data Federal agency leads defined for each theme Standardization of Framework representation non-existent until this year Multi-sectoral participation in ANSI-sponsored standards development teams for Framework underway to define Core representation Coordination of Framework data service providers to be formalized within each community

14 FGDC Federal Geographic Data Committee Content: Other Data US NSDI encourages the documentation, publication, and service of all types of geo- information Abundant environmental, imagery, and other non-Framework data are documented and available through Clearinghouse Data content standards for non-Framework data are encouraged to promote exchange

15 FGDC Federal Geographic Data Committee Semantic Interoperability Past FGDC Data Content Standards were not done using consistent modeling and implementation guidance, but provided, at best, semantic guidance on content Framework Data Content Standards now under development will include common core UML models, documentation, applying a feature cataloguing methodology, identifier systems, and define a single reference application schema for each theme to promote exchange

16 FGDC Federal Geographic Data Committee Semantic Resources Because geographic data is so diverse in its discipline and usage, the development of a common set of Theme Keywords to be used across all disciplines has been a problem ISO 19115 Categories provides one high level classification of generic data International cooperation is sought to identify and endorse a single set of thematic keywords with codes for common use!

17 FGDC Federal Geographic Data Committee Data Documentation FGDC Content Standard for Digital Geospatial Metadata (CSDGM) published in 1994 and revised in 1998, US contribution to ISO 19115 metadata standardization effort Over 130 government, commercial, and academic data catalogs exist in the US with hundreds of thousands of data sets described using CSDGM US will transition to adopting ISO 19115 Metadata Metadata points to direct data download in about 20% of the records

18 FGDC Federal Geographic Data Committee Community support Provide reference implementation software to promote adoption of common standards: – Collaborate with UNEP to maintain Enraemed ISO metadata collection software – Collaborate with FAO to modify data documentation and publishing framework Spatial Knowledgeware to support ISO and OGC specifications – Host and share metadata search “gateway” software

19 FGDC Federal Geographic Data Committee Discovery Services FGDC coordinates a network of six official search Gateways for accessing international content held in Z39.50 (ISO 23950) “GEO” Profile collections (includes non-FGDC metadata)

20 FGDC Federal Geographic Data Committee Discovery Services FGDC operates the GSDI global directory of servers to help selection of servers to target a full, distributed query NSDI/GSDI Discovery portals use searchable metadata fields, including spatial and temporal, and full text

24 FGDC Federal Geographic Data Committee Objectives of the Infrastructure To promote use and re-use of spatial data for multiple purposes by government and citizens To encourage participation of self-disciplined providers or data and services To establish baseline services that support community discovery and access to geo- information (directory of services, semantic registry, search gateways, gazetteer, reference software implementation)

25 FGDC Federal Geographic Data Committee E-government: Geospatial OneStop OMB has established 24 e-government initiatives across the U.S. Government to seek savings of scale by formalizing re-usable G2G services Geospatial OneStop accelerates implementation of the NSDI by: – Rapid development of Framework schema/standards – Reiterating asset management in Clearinghouse – Establishing G2G needs-based access via the Clearinghouse – Implementing high-grade federal map and data services online for Framework themes
