A second paper from a monograph devoted to the compilation and uses of transformed cartographic images focuses on analog/manual methods of areal image transformation—of particular relevance in areas and situations in which access to large volumes of computer memory is problematic. As such, it addresses problems relating to the transformation of a second type of transformed image—in which the areas of cartographic features of interest (rather than their linear dimensions) are scaled according to a nonspatial metric.
