GEOINT Standards Working GroupInaugurated January 2005

Working as a Community:

• Eliminate duplicative standards investments that deliver the same or similar capabilities

• Bring subject matter experts together within the DoD and IC to fully address GEOINT standards matters

• Enhance our ability to manage and share GEOINT data among disparate groups

UNCLASSIFIED


GEOINT Standards Working Group

• Leverage ongoing standardization efforts in the GEOINT industry as well as in DoD, and internationally

• Establish broad-based “focus groups” to serve as a forum for coordinating standards activities

• Manage GEOINT standards for the NSG community via the DoD Information Technology (IT) Standards Registry (DISR)

• Ensure that standardization efforts are closely aligned with implementation requirements and schedules

• Develop a GEOINT standards process that implements this strategy

“The formation of this new standards body [GWG] demonstrates a growing realization that geospatial applications must be standards-based if GEOINT is to be a world class citizen. Without continuing adherence to industry standards, spatial applications and programs simply cannot interoperate with other enterprise system components.”

National System for Geospatial Intelligence (NSG) Geospatial Core Metadata Profile (NGCMP)

• The purpose of this geospatial profile is to establish and define a systematic approach to managing, organizing, and disseminating standards to the development population. This document also establishes and maintains agreement between the customer and the project team on changing standards.

• Levels of NSG Geospatial Metadata - Various metadata profiling and harmonization efforts are being undertaken across the NSG community, among them the influence of current ISO standards development work to support NSG metadata requirements. To achieve this, metadata is developed at several different levels, and the GWG Metadata Focus Group (MFG) has developed recommended core metadata sets for each of these levels for use in the NSG community.

What is the NSG Geospatial Metadata Desk-side Reference ?

• A Document prepared by the Metadata Focus Group of the Geospatial-Intelligence Standards working Group to:– provide general guidance to users and developers and answer

questions on common issues– increase the ability of users and developers to more quickly develop

and manage Metadata within their organizations– leverage the resources of the GWG to coordinate Metadata profiling

and harmonization activities– increase the ability of the NGA National Center for Geospatial

Intelligence Standards (NCGIS) to provide service and assistance for Metadata standardization and implementation

• A Document which will be updated on a regular timeframe (anticipated to be semi-annually)
