본 연구에서는 하천관리지리정보시스템(RIMGIS) 내 하천유지관리부분의 활용성 향상 및 하천유지관리업무의 선진화를 위하여 항공레이저측량(LiDAR)과 고해상 영상자료를 기반으로 한 동적으로 변화하는 하상자료 관리 및 하상변동 분석 등의 하천유지관리기술을 개발하였다. LiDAR 및 고해상도 영상 형식으로 제작된 하천의 정밀지형도를 이용하여 동적으로 변화하는 하천의 하상자료 및 제방자료를 정보화하여 RIMGIS DB를 구축하고, RIMGIS와 연계된 하천유지관리체계 구축 및 하상변동 영향을 최소화하는 모니터링 기술을 연구하였다. 또한, 하천 지형정보 및 유지관리정보 등을 가지고 있는 RIMGIS의 기능과 자료구조를 보완하여 하천의 실시간 유지관리가 가능하도록 개선하며, 하상정보와 하천단면정보를 제공하여 하천통수단면 확보 등 구조적 기법을 이용한 하천기능 유지가 가능하도록 RIMGIS 보완 기술을 개발하였다. 이는 기존의 2차원 선(線)기반으로 제공되는 한정된 하천정보 및 정확성이 결여된 자료제공의 문제를 보완하여 지속적인 RIMGIS 기능개선과 유지관리 작업이 가능하도록 지원하고, RIMGIS 내 하천유지관리부분의 활용성을 극대화할 수 있는 기반기술로 이용할 수 있을 것으로 기대된다.

This study has developed a technology for river basin including the management of the data related with riverbed and the analysis of the riverbed maintenance based on the high-resolution imagery data and LiDAR (Light Detection and Raging) in order to enhance the utilization of river management by using RIMGIS(River Information Management GIS) and to acquire the advanced operation for river management. Using the detailed river topographical map specially designed in the form of LiDAR or high-resolution images, riverbed data and river bank channel information that are dynamically changed were informationized and established in the RIMGIS DB. At this stage, a monitoring techniques that is established in the river management system associated with RIMGIS and minimized the impact of riverbed maintenance (fluctuations) has been studied. In addition, functions and data structure of RIMGIS containing the information of geography and management of the river have been supplemented to make an improvement of the real-time management of the river. Furthermore, a technology that is capable of supplementing RIMGIS has been developed, making it feasible to maintain the river in use of structural method including an structural scheme of cross-section of the river by providing the information of riverbed and cross-section of the river. This is considered to solve an issue of insufficient data on accuracy and based on a lack of information of the river based on the two-dimensional lines, making it feasible to (steadily) improve the function of RIMGIS and to operate management tasks. Therefore, it is highly expected to enhance aforementioned technology of the river information management as a great foundation that maximizes the utilization of the river management to support RIMGIS for the development of national river management data.
