Most stereoplotter systems currently in use were designed primarily for producing contouring and profiling outputs on a coordinatograph. Recently, however, there has been an increasing need for topographic information in the form of digital grid-point elevation data. Whereas some existing systems can be used to extract this type of data, they cannot do it rapidly or efficiently. The AS-11B-X system is an experimental model of a new type of system intended explicitly for the collection of digital elevation data. The system was developed for Rome Air Development Center by Bendix Research Laboratories. The system achieves an increase in data collection rates of from 10-50 times that presently being obtained with conventional system at no decrease in accuracy. The AS-11B-X system obtains its high data-collection in parallel using digital processing. A combination of special techniques is used to simplify the digital processing and to reduce the amount of data storage required.
