The Accuracy Improvement of Geo-Spatial Information in Urban Area with terrain Classification
지형분류에 따른 도심지역의 지형공간정보 정확도 향상
Abstract
As the results of this study, the proposed method of this study which is increased to accuracy of DEM by classification of terrain is better than accuracy of DEM which is automatically generated by digital photogrammetry workstation system(DPWS). And, the edge detection method which is proposed by this study is established to extraction of geo-spatial information in ortho image.
