| Abstract: | This paper first introduces the significance and presents research situation of automatic extracting linear object from remote sensing image. Then, an approach of automatic extracting linear object from remote sensing image is proposed, which considers old GIS data. The approach includes image preprocessing, image and GIS data matching, skeleton tracking, lines grouping and data simplifing. Finally remote sensing image and its old GIS data are experimented. Results of the experiment show that this approach is feasible and effective. |
