ABSTRACT
Visual perception is reviewed in relation to the search for principles in map design. Various cues of 'depth' are examined as aids in the specification of the qualities and dimensions of map symbols. Maps are analysed on the basis of 'receding planes', each plane containing a specific selection of graphic information. A design procedure is outlined in this content, and finally an example of a thematic map, the Residential Land Use of Glasgow-1965, is presented in detail. Over recent years much has been written on the aesthetic principles and the technical aspects of designing maps. The first stage of the investigation concerns the size, brightness and association of meaningless shapes. Cognition lends further clues to anchor the figure/ground relationship. The cartographic problem of separating the layers of graphic information which comprise the map was referred to initially. Maps consist of elements which are conveniently classified under four headings: areas, lines, points and names.
