Development of integrated geophysical and geological information databases and their management system on sharing

摘要

We develop the integrated geophysical and geological information databases of the whole of Japan.We use various available data in all of Japan and build a database by integrating such information. Standardizingand integrating different kinds of data such as geological data and geophysical data, we develop adispersion-managed type network system to open each database distributed to each organization and utilizethem each other. In order that many organizations can join the database, cutting the cost of installation, operationand maintenance fee of the system and securing mutual exploitation of data are desired. The managementsystem on sharing databases is developed by the following concepts. 1) Some open source software is adoptedto cut the initial cost. 2) One organization runs a portal site, and others are responsible only for their own database.3) Adopting the world standard, this system is more compatible with others or GIS software.
