Cartography is related to, but different from other forms of visual communication. Cartographers must pay special attention to coordinate systems, map projections, and issues of scale and direction that are in most cases of relatively little concern to other graphic designers or artists. But, because cartography is a type of graphical communication, some insights to the demands of cartography can be gleaned from the literature of graphical communication and statistical graphics. Often cartographers are faced with some of the same challenges faced by graphical designers and can learn much from their insights. As you begin to study cartographic design, you may find it useful to consult some of the standard works on graphical communication. You will find the following books particularly interesting, and maps are often the focus of discussion.
