摘要:Digital large format aerial cameras can produce as many images as a user pleases, and yet the costs of the imagery do not increase, in fact they decrease. This is a vast difference from traditional film-based photogrammetry where minimizing the number of film images was a basic tenet of the discipline, since a project's costs were directly proportional to the number of images needed to complete it. Minimizing costs no longer is defined by minimizing the number of images, but by minimizing the use of human labor hours. The entire economy of aerial imaging is changing with the transition to digital cameras and the full digital workflow. This will change the market's behavior, both on the side of the end-users of photogrammetrically collected data as well as on the side of photogrammetric organizations. More images will be created per project, mapping repeat cycles will shorten, costs per project will decrease, new data products will emerge and the competitive cost structure in photogrammetric organizations will come under intense pressure
