| Abstract: | With the development of Photogrammetry technology, the production and overall update for Orthophoto has made a great progress, however, there is still short of research and practice on the partial image updating,also some de- mands are needed in some emergency surveying and mapping support tasks. To meet the actual demands of emergency sur- veying and mapping support, this paper studies the methods related to the technology of partial Orthophoto updating ,and the effectiveness and feasibility of this method is proved by experiment. |
