摘要

Recently, impervious surfaces in urban areas are rapidly increasing due to industrialization and urbanization. Since impervious surfaces have caused an increase in urban flooding and non-point pollution, there is a need to manage them systematically. However, there is no impervious surface map applicable to the spatial distribution grasp and spatial analysis. There is even no map production methodology reflecting the characteristics of urban areas. Therefore, this study aims to suggest a methodology of GIS-based impervious surface map production applicable to the management of impervious surfaces in urban areas. For this purpose, various geographic features in urban areas were classified and the classification standard of pervious and impervious surfaces for each geographic feature was defined. The spatial data to be used in extracting and delineating each geographic feature in the GIS were investigated and their applicability was analyzed. As a result, it was found that it would be possible to identify the state of land cover and geographic features by overlaying and investigating the spatial data such as a land cover map at intermediate level, a high-resolution satellite image, an ortho-aerial photograph and a digital topographic map. To verify the suggested methodology, the spatial data from Bugae-dong(total area : 2.58□), Bupyeong-gu, Incheon city, South Korea, were collected and they were applied into the impervious surface map production. As a result, The area of Bugae-dong measured impervious(l .87□) and pervious(0.71□) area. Also, impervious surface map was found to have the largest number of polygons(6,594) and vertices(137,890). It was possible to produce the impervious surface map in a high spatial resolution, and it was demonstrated that an impervious surface map could be produced using the suggested methodology. In conclusion, future research would need to produce an impervious surface map of the whole country using the suggested method, and furthermore, this should be applied to the systematic and quantitative management of impervious surfaces.
