| Abstract: | Sharing of geographic information is important because the more it is shared, the more it is used, and the greater becomes society's ability to evaluate and address the wide range of pressing problems to which such information may be applied. To facilitate sharing, the Geographic Information System (GIS) user and research communities must to establish a structured set of standards for information concerning objects or phenomena that are directly or indirectly associated with a location relative to the Earth. These standards may specify the methods, tools and services for both technical and institutional aspects of collecting, structuring, analyzing, accessing, presenting, disseminating, integrating, maintaining spatial data and transforming such data in digital/electronic form between different users, systems and locations. In this paper, the newest development status of geographic information standards is introduced at International Organization for Standardization (ISO), Open GIS Consortium (OGC) and the European Committee for Standards(Comité Européen de Normalisation, CEN). The organizaion structure, Working items of geographic information standards are presented at ISO/TC 211, OGC and CEN/TC 287 and the strategies for developing geographic information standards in China are proposed. |
