Construction of a geospatial data sharing and mutual-use by GIS technology

Nowadays, Japan is facing a variety of social issues, such as environmental and energy problems, maintaining and managing public infrastructure, ensuring safety and security in the community, and recovering and rebuilding from disasters, among other things. These issues are overlapping one another and are becoming opaque to the public. However, the utilization of geospatial information can help to resolve such issues. The development of geospatial information and the promotion and high level of its utilization through Geographic Information Systems (GIS) are important for achieving a society. In this paper, with advancements in information and communication technology such as the popularization of cloud computing, expansion of services through Mash up, open-sourcing, etc., GIS-based comprehensive and systemic server system that are a synthesis of individual systems and services have been developed. A framework is being developed for enabling the comprehensive searching,acquisition, development and utilization of geospatial information. A web application using Silverlight technology has been established to examine the server scalability, database accessibility, and applications of client-sides.
