Civil infrastructures should be safe and kept in good condition, because they are important roles in economy and emergency services. If large-scale damage occurs to infrastructures in urban areas and they cannot be used, many aspects of life will be affected. Thus, it is important to protect infrastructures from large-scale damage in order to maintain services for the public. For local governments, it is necessary to act disasters quickly. Disaster information should be collected and shared quickly for acting rescue and rehabilitation smoothly and effectively. However, in Japan, there are several problems for sharing the information in stakeholders. In this paper, a disaster information sharing system was proposed. The paper discusses the problems for submitting and sharing in disasters of earthquake, cataracts, flood, landslide, and so on. The prototype system was designed and developed using Web GIS. The system was used GeoServer and OpenLayers as open source Web GIS, and PostGIS and PostgreSQL as DBMS. The collection function was worked out by posting e-mail of disaster abstracts and photographs in site from local government staff and private engineers. The system put the point on digital map automatically analyzing e-mail. Local governments share the disaster information using Web GIS. The prototype was used for windstorm and flood disaster response exercise in local government for testing the usability and application in June 2013. The results showed the ability of the system for sharing disaster information. However, they showed the problems of usability and everyday use.
Abstract:Road maintenance should be carried out effectively. In this paper, the utilization system and operation model were constructed for operating the spatial data infrastructure in road maintenance. A referring system of location reference points, the utilization of road occupancy continuation, and the system of road coordination conference were developed using spatial data infrastructure. The referring system of location reference points adopts open source software for utilizing widely. This paper proposed the operation model of spatial data infrastructure for updating and utilizing effectively. The roles of public and private coordination are reviewed. The roles and business model of governing structure were proposed.

In this paper, the coordination and registration system of road occupancy permission was developed for reducing the work process and cost. The system is internet registration system of road occupancy permission, and is developed by public and private cooperation. The spatial data is standardized for using in common with public and private. The three functions are developed (1) XML database for exchanging and sharing the characteristic information smoothly, (2) online storage for exchanging large spatial data and drawings, (3) WebGIS for editing and referring the location data. The system is applied to actual operation, and examined the effectiveness.
