Vision and Mission The Open. GIS® Vision Achieve the full societal, economic and scientific benefits of integrating location resources into commercial, institutional and organisational processes worldwide. The OGC Mission To serve as a global forum for and lead the development, promotion and harmonization of open and freely available geospatial standards.

Geography Mark-up Language (GML) application schema examples • City. GML (http: //www. citygml. org) – Common information model for the representation of 3 D urban objects. It defines the classes and relations for the most relevant topographic objects in cities and regional models with respect to their geometrical, topological, semantic and appearance properties. Included are generalization hierarchies between thematic classes, aggregations, relations between objects, and spatial properties. • Geo. Sci. ML (http: //www. opengis. net/Geo. Sci. ML/) – Geo. Sci. ML accommodates the goal of representing geoscience information associated with geologic maps and observations, as well as being extensible in the long-term to other geoscience data. – An approved standard in that community • Marine. XML (https: //www. seegrid. csiro. au/twiki/bin/view/Marineweb/Marine. XML) – Marine Data exchange based on ISO 19136 (GML Feature Types). The alignment between ISO and OGC on ISO 19136 makes GML the clear (only) choice for developing an XML-based framework for marine data exchange. • AIXM/GML (http: //www. aixm. aero) – The Aeronautical Information Exchange Model (AIXM) Specification supports the data -centric environment. It supports aeronautical information collection, dissemination and transformation throughout the data chain OGC Copyright 2011, Open Geospatial Consortium • Making Location Count 20
