This research addresses the problem of revising existing orthoimages using updated information that are captured from single aerial imagery. The proposed revising approach applies image resection followed by mono-image intersection employing a DEM for the imaged area. The data used in the research experimentation consists of a high resolution aerial image captured recently with the digital aerial camera UltraCam-D, a photogrammetrically generated DEM, and an orthoimage. The image format is 7500 pixels along track by 11500 pixels across track and the pixel size is 9 m by 9 m. It has a 10-cm ground sample distance. The DEM and the orthoimage have 1-m and 20-cm ground sample distances, respectively. Fifty four common points, which appear distinctly in both the test image and orthoimage, are selected and measured interactively. They are employed in the image resection, mono-image intersection, as well as accuracy evaluation of the approach. The yielded accuracy figures, which are smaller than the ground sample distance of the orthoimage, confirm its validity for updating orthoimagry.
