The development of many softcopy photogrammetric systems and + is a characteristic of the direction of these changes. A significant segment of the user community is oper à still cautious about these new systems coming to the marketplace with very impressive claims. Furthermore, it may be safe to assume that established photogrammetric mapping production facilities b) Ac have already invested a considerable resources in plotting machines, photographic equipment, and operator training. Therefore, it would be it difficult to shift into a new direction, which not only will SX it render the existing equipment outdated, but it will also require new major acquisition. It is evident for di that no standardized evaluation yet exists that compares some softcopy systems to a conventional Con photogrammetric workstation. Such unbiased evaluation is needed to show users the strengths, and auto of course the weaknesses, of softcopy photogrammetric systems. The Laboratory for Softcopy gener; Photogrammetry at the University of Wisconsin-Madison is undertaking an evaluation project of a COD Ve number of commercially available softcopy photogrammetric systems. The selection of these systems Con is controlled by specific factors, which are budgetary constraints, limited resources of qualified testing autom staff, and willingness of manufacturer’s participation. In this paper, evaluation objectives, strategy, gener; and preliminary results are presented. In view of certain applications, softcopy systems are found to ATO: be competitive, if not superior, to conventional photogrammetric operations. A number of specific The V factors, however, must be carefully considered, such as data volume, operator skills, and automation. that e direct indire The Wisconsin Department of Transportation c) Sp 1.
