하천망분석도(KRF)의 활용성 증대를 위한 공간데이터 구조 개선에 관한 연구

National Institute of Environmental Research (NIER) has developed the Korean Reach File (KRF) for scientific and systematic analysis of variables related to water quality, pollutant sources and aquatic ecosystems in consideration of steam reach networks. The KRF provides a new framework for data production, storage, management and analysis for water related variables in the relation with spatial characteristics, connections, and topologies of stream reaches. However, the current version of KRF (ver.2) has a limited applicability because its nodes include not only the stream points based on topological characteristics but also those based on water quality monitoring stations, which may undermine its generality. In this study, a new version of KRF (ver.3) was designed and established to overcome the weak point of the version 2. The version 3 is a generalization of the old KRF graphic data and it integrates the attribute data while separating it from the graphic data to minimize additional work that is needed for data association and search. We tested the KRF (ver.3) by applying it to actual cases and its convenience and adaptability for each particular application was verified. Further research should focus on developing a database link model and real-world applications that are targeted to process event data.
