The Open Geospatial Consortium (OGC®) is calling to vendors doing business in India for participation in its latest Interoperability Plugfest. The Department of Science and Technology (DST) is interested in planning and convening an Indian OGC Interoperability Plugfest. The focus of the plugfest is to better support the National Programs on Smart Cities and National GIS / National Spatial Data Infrastructure (NSDI) of the Government of India. This initiative will create a supportive environment for public private partnerships to actively test their ability to apply OGC standards in improving the ability and efficiency of accessing, sharing, and processing various types of government geospatial data & information. The Indian OGC Interoperability Plugfest focuses on an initial set of OGC standards to be of critical importance to support advancement of the NSDI for sharing geospatial data & information across the Indian community, including both the public and private sectors.
