Lexicon of Terms and Definitions Added
Introducing the NSDI Lexicon: A Unified Language for Geospatial Collaboration
![]()
The Federal Geographic Data Committee (FGDC) is proud to announce the launch of the NSDI Lexicon, a centralized resource designed to standardize terminology across the National Spatial Data Infrastructure (NSDI) ecosystem. This new tool provides a common language for Federal agencies, State and tribal governments, academia, private-sector partners, and international organizations engaged in geospatial data development and integration.

Why the NSDI Lexicon Matters
As geospatial data becomes increasingly critical for decision-making, interoperability, and innovation, consistent terminology is essential. The NSDI Lexicon ensures clarity and alignment by:
- Defining key terms used in geospatial policy, standards, and technology.
- Supporting compliance with the Geospatial Data Act of 2018 (GDA).
- Enhancing communication among diverse stakeholders in the NSDI community.
Key Features
- Comprehensive Definitions: Covers terms related to data standards, metadata, governance, and emerging technologies.
- Searchable Interface: Quickly find definitions and related concepts.
- Linked Standards & Policies: Connects terminology to FGDC standards, ISO references, and GDA provisions.
- Dynamic Updates: Maintained by FGDC to reflect evolving practices and innovations.
Who Should Use It
The NSDI Lexicon is an essential resource for:
- Federal Agencies implementing GDA requirements.
- State and Tribal GIS Coordinators aligning with national standards.
- Academic researchers and educators.
- Private Sector & Academia seeking clarity in contracts and research.
- International Partners harmonizing global geospatial practices.
Example Terms
- National Spatial Data Infrastructure (NSDI): A coordinated national effort to develop technologies, policies, and standards that enable the sharing and use of geospatial data.
- Metadata: Information that describes the content, quality, condition, and other characteristics of data.
- Interoperability: The ability of different systems and organizations to exchange and use geospatial data seamlessly.
