A GIS data updating method with video

Abstract : We present a method for extracting and updating Geographic Information System (GIS) data from video. This paper uses a ground-view video sequence as input data. In the first step, feature points are extracted from video, which provide the structure information for architecture facade reconstruction; after discarding outliers, we create the footprint and reconstruct a 3D model. The second step is the back-projection process. In the third step, we correct the footprint and update it by using user knowledge. Finally, this information is used to update GIS.
