The Implementation of Graphics Superposition on the APPS-IV Analytical plotter,
Abstract
The APPS-IV analytical plotter has been modified to permit the superposition of graphics data from a data base into the optical path. This data is projected into the stereo-model in photo image coordinates. Under real-time microprocessor control, the graphics display is translated on the face on the CRT to maintain registration with the image as the stage is moved. With graphic superposition, geographic data can be displayed directly in the stereo model as it is digitized. In addition, data previously compiled can be displayed as well as information from entirely different sources. (Author)
