Symobls and Meaning in Topographic Maps: Some Limintations Due to Aspects of Map Design.
Keates, J. S.
The approach to topographic map production has been highly organized and systematic with respect to scale, projection, grid, etc., so that the user can expect a high degree of locational accuracy. Less attention has been given by cartographers to symbolic information yielded by the map. Symbolization (information reduction) is required at all levels --including that of the survey. A number of factors should be considered in order to clarify what aspect of the feature the symbol is to concentrate on and what is being omitted, so that there is a clear identification of what the symbol is intended to convey to the user. If cartographic symbols can be devised to convey specific attributes of represented features, two other considerations emerge --the graphic structure of the symbols, and the way the user responds to them. If premises are acceptable, the following conclusions can be drawn: 1) design of map symbols cannot be isolated from data collecting; 2) if informational content of maps is be increased and improved, there cannot be heavy reliance on photo-interpretation; 3) a more deliberate and systematic attitude about manipulation of graphic image will be necessary to make the map a more effective communication; 4) present interest in a digital form of map information makes sense only if equivalent standards can be applied and maintained.
