A study on GPS management system on the basis of technology

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.
