Abstract | Geography spatial data sharing and interoperation are the key technology of digital earth as well as digital city. They are also the precondition of national spatial information construction and spatial data utilization. Based on the analysis of several key technologies such as ontology, GML, GIS data integration and interoperation as well as their present research status, the system framework of GIS data integration and interoperation is studied firstly in this paper. Then, an ontology and GML-based spatial data exchange model and SVG-based information visualization model are proposed. Finally, by describing specific spatial concepts and their relationship with ontology, and labeling data model with ontology information, the data model not only has structure information but also has semantic information. Which provides a well support for the realization of full semantic data exchange. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
