Abstract: The goal of OpenGIS specification is to solve the geodata sharing and interoperable geoprocessing, and to provide the service of the geodata sharing and geographical information. SIG integrates all the online resource, including geodata, computer and equipment and service, to serve for the needs of the society. The OpenGIS specification, as popularly supported interoperability specification of geodata, is one of the supporting technologies for SIG. This paper presents the goal, status of OpenGIS specification, the concept of SIG, and the relation and differences between them.
