Computer Cartography. Resource Paper No. 17.
Peucker, Thomas K.
The theory of computer cartography is emphasized in an attempt to bring some related ideas together within a single framework. The paper is part of a series designed to fill the gap between significant research in geography and accessible materials. Part I introduces information theory and cartography, the features of numeric cartography and their structures, points, lines, and surfaces and hardware, and one mapping system. Next, some theory of the surface is presented concerning the information content of a surface-point, surface behavior, and surface features and information hierarchies. Prediction, spectral analysis, and picture processing are discussed in relation to surface processing. The representation of surfaces, lines, and points are discussed in terms of three-dimensional information elements, the picture plane, visibility, block diagrams, planimetrically correct surface representations, isarithms, data grids and functions, and points and lines. Part VI on data structures deals with coding, line-storage and data-organization. Finally, high-accuracy systems and small interactive systems and their applications are examined. Further reading, a glossary, and a list of major programs used for the production of the figures in the paper are included. (Author/KSM)
