Expected problems in the Production of Nationwide Seamless Map Using Heterogeneous Spatial Data - with Emphasis on Digital Maps

이질적인 공간 데이터의 통합을 위한 범 국가적 연속지도 구축 방안 - 수치지도를 중심으로

Since the first phase of NGIS (National Geographic Information System) project was launched in 1988, various types and spatial database has been produced and updated. With recent developments in the information technology, the application of spatial data has increased in amount as well as in the coverage of the area of interest. There is a need for production and management of a nationwide single continuous digital map. This paper looks into three problems of map edge matching when dealing with such a task : 1) different scales of adjacent maps, 2) different time of capture between adjacent maps, and 3) different responsible organization where map matching has not been peformed along the boundary.
