GPS 도면 지식정보 관리시스템 기술기반에 관한연구

Korean railway network GIS?based information system requires so much cost and time. One of the difficulties is due to the fact that GIS?based information system requires the feature database for GIS, which is generally built manually from many as?built drawing files. In order to build?up database automatically Using GPS coordinates, this study suggests the automatic data conversion from electronic drawings to make feature database for GIS. The proposed method can be applied to build large?scale railway facility management system.
