Abstract

In this paper, an approach for the automatic extraction of linear feature, in particular roads, from digital aerial imagery is proposed. In some literature, knowledge based automatic road extraction were done with geo-referenced imagery which can automatically register old road map to new imagery as knowledge. Whereas the automatic geo-reference and road extraction are processed simultaneously in this approach, which can benefit and depend on each other. The implemented approach is based on Snake model and template matching with the new aerial imagery and old road map. The presented procedure does not need much manual interaction and therefore has the potential to be integrated into an automatic workflow. Potential applications of the approach are manifold, like automatic change detection of road and three-dimensional reconstruct of man-made objects such as road and building wtih some minor modifications.
