A Study on the Improvement of RIMGIS for an Efficient River Information Service

The RIMGIS(River Information Management GIS) has been developed since 2000 for public service and practical applications of related works after the standardization of national river data such as the river facility register report, river survey map, attached map, and etc. The RIMGIS has been improved in order to respond proactively to 2012년 11월 3일 접수 Received on November 3, 2012 / 2013년 1월 14일 수정 Revised on January 14, 2013 / 2013년 1월 23일 심사완료 Accepted on January 23, 2013 * 본 연구는 국토해양부 건설기술혁신사업의 연구비지원(11기술혁신CO6)에 의해 수행되었음. 1 한국수자원공사 K-water 연구원 수자원연구소 Water Resources Research Center, K-water Institute, Korea Water Resources Corporation ※ Corresponding Author E-mail : hyosok.chae@kwater.or.kr A Study on the Improvement of RIMGIS for an Efficient River Information Service 16 change in the information environment. Recently, Smart River-based river information services and related data have become so large as to be overwhelming, making necessary improvements in managing big data. In this study a plan was suggested both to respond to these changes in the information environment and to provide a future Smart River-based river information service by understanding the current state of RIMGIS, improving RIMGIS itself, redesigning the database, developing distribution, and integrating river information systems. Therefore, primary and foreign key, which can distinguish attribute information and entity linkages, were redefined to increase the usability of RIMGIS. Database construction of attribute information and entity relationship diagram have been newly redefined to redesign linkages among tables from the perspective of a river standard database. In addition, this study was undertaken to expand the current supplier-oriented operating system to a demand-oriented operating system by establishing an efficient management of river-related information and a utilization system capable of adapting to the changes of a river management paradigm.
