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

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

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

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

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

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)

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

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

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
FGDC
Federal Geographic
Data Committee
Content: Other Data



US NSDI encourages the documentation,
publication, and service of all types of geoinformation
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
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
FGDC

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!

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
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
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)
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

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 geoinformation (directory of services, semantic
registry, search gateways, gazetteer, reference
software implementation)

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

What is the Geospatial One-Stop Portal?




Middleware that integrates access to
distributed community data services
Community-wide access point for all
