A summary of softcopy photogrammetric workstations developed by the General Dynamics/Helava Associates, Incorporated (GD/HAI) team during the past ten years is given. The summary starts with the Digital Stereo Comparator/Compiler (DSCC), and also includes the DMA workstation, the Digital Imagery Workstation Suit (DOWS), the Digital Stereo Photogrammetric Workstation (DSPW), the HAI-750, and the HAI-500. Some of the latest efforts have been oriented toward the commercial market place. The key aspects discussed in this paper include the handling of large amounts of imagery, geometric handling of images, elevation extraction, and feature extraction. Approaches and solutions to generic technical problems are highlighted even though only top level descriptions are given.
