AS-11/B Stereoplotter Experiments and Studies.
Abstract
A study was made of the utility of the automated analytical stereoplotter in the generation of advanced cartographic products such as obscuration charts, radar predictions, terrain elevation grids, and off-line orthophotos. Although both on-line and off-line methods were investigated, emphasis was placed on methods which use the stereoplotter system in an on-line manner to directly generate the cartographic product. A computer program was developed for the AS-11B automated analytical stereoplotter system to generate obscuration charts. In this study, methods were developed for generating the various cartographic products using the automated analytical stereoplotter system. Experiments were performed to automatically measure and determine the quality of pass-points. Pass-point data was automatically measured and recorded on magnetic tape using the AS-11B automated analytical stereoplotter system. This data was then analyzed off-line on a GE-645 computer system. From the pass-point data, a figure-of-merit was computed for each pass-point. This figure-of-merit indicated the quality of the recorded pass-points. (Author)
