| Definitionskos:definition | The National System for Geospatial-Intelligence (NSG) Application Schema (NAS) is an ISO 19109 compliant application schema that defines the conceptual model for identifying and encoding feature data in the U.S. National System for Geospatial-Intelligence (NSG). NGA utilizes the open source software tool ShapeChange as an integral piece in NAS development. This tool is used to take NAS-based UML models and create Extensible Markup Language (XML) and Resource Description Framework (RDF) based schemas. Testbed-12 began development of capabilities for extracting profiles supporting specific mission functions from the full NAS content. Testbed-13 further refined the approach to NAS Profiling by investigating how a specific profile (Urban Military Profile) can be processed in an automated way and used to derive implementation schemas for the OGC standards CDB and CityGML. This OGC Engineering Report describes: The specification of a NAS-based Military Urban Profile as a Unified Modeling Language (UML) model (chapter 5); How mission-specific sub-profiles can be specified and maintained using ShapeChange and the new ShapeChange Profile Management Tool (chapter 6); and How the model and profile information are processed to derive output for a CDB data store (chapter 7, chapter 8) and a CityGML Application Domain Extension (chapter 9). This work provides insights into: The requirements and constraints on managing profiles of complex ISO 19109 compliant application schemas such as the NAS; and Using a model-driven approach to generate implementation schemas of an ISO 19109 compliant application schema profile for different environments. The target audience of this document is anyone interested in these topics. The implementation environments discussed in this report are the OGC standards CDB and CityGML. The profiled application schema is the NAS. This report assumes that readers are familiar with the key concepts and technologies discussed in this document. This document does not provide an introduction to them, but the table below provides a brief summary and pointers to more information. |
