This project identified the process, problems, challenges, accuracy, and quality control for urban high-resolution (e.g., 6-inch or one-foot) gray and color−infrared high-resolution digital orthoimagery. The report presents experimental results that exposed the problems of traditional orthoimage generation methods, such as ghost images, occlusion and building lean, shadow of the buildings, inaccuracy of DSM, incomplete refilling to occlusion, different geometric accuracy of adjacent orthoimages, etc. It presents an alternative approach that resolves these problems. Testing of the alternative approach was conducted.
