Abstract

Digital Photogrammetric Workstations (DPWS) have become a major focus of research within the photogrammetric community in the last year. This paper presents the state-of-the-art of DPWS. A DPWS is the main component of a Digital Photogrammetric Systems (DPS). A DPS is defined as hardware and software for deriving input data for Geographic Information Systems (GIS) as well as for Computer Aided Design (CAD) systems and other photogrammetric products from digital imagery using manual and automatic techniques. Besides the DPWS itself a DPS also includes A/D and D/A convertors for the imagery (digital cameras, film scanners, output devices for producing film and paper hardcopies). First design issues of a DPWS are addressed. Then, the question of automation versus interaction is discussed, and it is pointed out, where automation is possible in the chain of processing digital imagery. Subsequently a classification of the different kinds of DPWS according to their products is given. Then first experiences and results obtained by civilian mapping organizations involved in digital photogrammetry and using DPWS are described. Finally requirements for a broader use in practice and trends for further development in digital photogrammetry and in DPS are pointed out.
