도시지역 대축척 토지이용현황도 일반화를 통한소축척 지도 제작의 타당성 연구 - 서울시의 1：1,000 토지이용현황도를 대상으로 -

Abstract

Seoul city government has published 1:1,000 scale landuse map by using 1:1,000 digital topographic data and conducted field survey for city-scaled urban development plan. Also, National Geographic Information Institute that takes charge in producing and maintaining nationwide digital maps, has been mapped landuse data with different scale of 1:25,000 by interpreting aerial photographs for nationwide land use planning. As a result, these projects duplicated the time and financial investment in map generation.Therefore, this research aims to examine validation of small scale map generation method as generalizing 1:1,000 scale landuse map into NGI's 1:25,000 landuse map, which will prevent the duplicated investments in map generation of both agencies and enhance the interoperability of these data. For the purpose of determining the difference of classification and generation method between these agencies' landuse map, we carried out pilot study on Seongdong-Gu, Kwangjin-Gu, Dongdaemun-Gu using classification and symbolization methodology which reclassifies items after comparing among classification items and boundary symbolization. With such a methodology, we* 서울시정개발연구원 도시정보연구센터 연구원generated 1:25,000 scale landuse map from Seoul city government's 1:1,000 scale map, and achieved 83% accuracy rate. The more information exchanges between those agencies in near future are recommended to meet more reliable data level.키워드(KeyWords)：일반화, 소축척지도, 대축척지도, 토지이용현황도generalization, small scale map, large scale map, landuse map
