NGA documents OGC Web Services Architectural Profile for the NSG

General feature model – metamodel of feature types Geographic feature – feature associated with a location relative to the Earth. GEOINT Discipline– encompasses all activities involved in the planning, collection, processing, analysis, exploitation and dissemination of spatial information in order to gain intelligence about national security or operational environment, visually depict this knowledge and fuse the acquired knowledge with other information through analysis and visualization processes. [NSG Statement of Strategic Intent] GIG - Global Information Grid - provides authorized users with a seamless, secure, and globally interconnected information environment, meeting real-time and near real-time needs of both the warfighter and the business user. GML – Geography Markup Language Interface – named set of operations that characterize the behavior of an entity [6] Interoperability - capability to communicate, execute programs, or transfer data among various functional units in a manner that requires the user to have little or no knowledge of the unique characteristics of those units [ISO 2382-1] Map projection – coordinate conversion from a geodetic coordinate system to a planar surface. Metadata – Information that describes, or supplements, the central data. It provides information about the identification, the extent, the quality, the spatial and temporal schema, spatial reference, and distribution of digital geographic data. National System for Geospatial Intelligence NSG - Combination of technology, policies, capabilities, doctrine, activities, people, data and communications necessary to produce geospatial intelligence GEOINT in an integrated multi-intelligence, multi-domain environment. [NSG Statement of Strategic Intent] OGC – Open Geospatial Consortium Operation – Specification of an interaction that can be requested from an object to effect behavior. [ISO 19119] Property - A facet or attribute or an object referenced by a name ORM – OGC Reference Model Service request - A request by a client of an operation from a service. Service - A collection of operations, accessible through an interface that allows a user to evoke a behavior of value to the user. [ISO – 19119] Service chain - sequence of services where, for each adjacent pair of services, occurrence of the first action is necessary for the occurrence of the second action [ISO 19119] Service Framework - a partially complete sub-system that is intended to be instantiated. It defines the architecture for a family of sub-systems and provides the basic building blocks to create them. Spatial Reference System – As defined in the OpenGIS Abstract Specification Topic 2 and ISO 19111. Viewpoint – form of abstraction achieved using a selected set of architectural concepts and structuring rules, in order to focus on particular concerns within a system. [ISO-10746-2] VPF - Vector Product Format - is a standard format, structure, and organization for large geographic databases that are based on a georelational data model and are intended for direct use.
