Building Local-Government Service-Oriented GIS Through 2007 Chuetsu-Oki Earthquake Experience

Implementing enterprise geographic information systems (EGIS) for local governments usually involves high initial and follow-up cost, e.g., for data maintenance, caused by excessively detailed base maps based on public survey specifications, even though suchmaps are not needed for most municipal operations. This study analyzes requirements for reducing costs of an implementation and maintenance of local-government EGIS (LGEGIS). The study also analyzes goals for local-government EGIS (LGEGIS). Both the analysis in this research are based on the case of the Kashiwazaki City EGIS in response to the 2007 Niigata Chuetsu-oki Earthquake.
