ISO Standard 19116 For Positioning Services In Geographic Information Systems And Geomatics

T. Mauney

Abstract:	As location aware appliances are evolving, the need for interoperability of both datasets and GIS software has motivated the development of national and international standards for software architecture and for data content. The International Organization for Standardization created Technical Committee 211 -- Geographic Information / Geomatics for the development of high level international standards for GIS by the open consensus process. Over a period of five years, these standards have evolved from the initial concepts to refined documents approaching promulgation as formal international standards. The ISO TC/211 Positioning Services Standard provides a high-level object oriented model allowing generalized positioning services to interface with the ISO reference model for GIS so that information required for interoperability can be transferred. This includes communication of equipment descriptors, session identification, coordinate system, operating parameters and performance indicators in addition to the position values themselves. The open structure of these high-level standards allows their underlying object oriented approach to be applied in many implementations and provides the means to identify the commonalities between disparate data structures so that interoperable tools can be developed that facilitate data exchange and international cooperation. Within the standardized formulation of positioning services, position reports, position quality reports, coordinate system selection, and even instrument identification metadata can be communicated in an unambiguous way to a client system that performs position dependent actions. Client systems could include navigation aids, resource lookups, AVL and Tracking tools, recording systems and so forth. As abstract standards, the ISO TC/211 standards allow wide possibilities for compliant implementations, including the possibility of industry oriented implementation standards. For Positioning Services, communication protocols implementing the standard are left open so that harmonization with well-known standards such as the NMEA-0183 is facilitated.
