Book Description
The report presents a logical design of a natural terrain radar land mass simulator, techniques for incorporating radar effects, and cultural terrain into the simulator, and relationship between simulator design and specific operational requirements. The results of this work indicate that the techniques developed are feasible from an engineering standpoint but are impractical due to cost considerations. A firmer understanding of the information content of maps and digital representation techniques must be established to compress the data to a degree whereby an economically feasible device can be developed.

Book Description
To generate input data with a 50-foot resolution and fifteen shades of gray for advanced high-resolution digital radar simulators, this research examined and defined data sources and processing techniques. Limited to the Continental United States and to unclassified information, the data sources included all known aerial mapping imagery and topographic maps. All existing image processing techniques and devices were examined to define their operating principles. This review led to the conclusion that adequate geometric information for radar simulation data could be extracted from the current data sources and that existing processing capabilities could be combined into a feasible automatic system. In related work, non-parametric three-dimensional resections were calculated on a digital computer, and mathematical concepts were developed to give a computer system the capability of interpreting the physical characteristics in photos by using cues as done by a trained photo interpreter.

Book Description
The report is on an initial investigation of the preparation and utilization of maps in digital form. The program is an outgrowth of an investigation of digital techniques for radar landmass simulation, wherein it was found that information was lacking about the properties of natural terrain and cultural complexes, and thus about the maps themselves which must be used as input data for the simulation. The study reported herein is concerned with means of representation of maps in digital-computer-readable form, and with the means of reconstruction of the map for radar simulation or other purposes. Some techniques of information theory are applied with an ultimate goal of developing a measure for the information content of a map -- the minimum amount of data that is necessary to represent a portion of the real world under stated conditions of accuracy, error, or fidelity. The gradient vector method of encoding the data is derived on the basis of this knowledge, and experiments are reported that illustrate the degree of data compression that can be achieved by this method, as compared with the method of contour tracing that was reported in the preceding program.
