GIS를 이용한 도시유역 토지이용특성 추출과 활용방안
A methodology to extract landuse properties in urban areas and its application using GIS

초록
The accurate estimation of the area of individual landuse in each subbasin is crutial. However, because of the complication in landuse of an urban watershed, it is almost impossible to estimate the area of individual landuse in each subbasin by manual ways. For this reason, in this study, a systematic methodology is suggested to estimate individual landuse area of each subbasin using GIS. To construct data for applying GIS, CAD data including sewer layout and landuse are collected and converted into the GIS data such as shape files. An urban watershed, then, is divided into subbasins with respect to sewer layout and landuse. For each subbasin, the area of individual landuse including road areas are estimated by applying several GeoProcessing functions. The proposed methodology is applied to the Goon-Ja watershed in Seoul to demonstrate its applicability and it is concluded that the proposed methodology can estimate individual landuse properties efficiently and accurately.
