Abstract
The problem of exchange of digital cartographic data is introduced, and the different alternatives to it are discussed. The outline of a unified cartographic theory is presented as the framework for the development of a methodology for the theoretical evaluation of exchange procedures. A map representation theory is developed for evaluation of any standard or format for the exchange of digital topographic data among computer-aided mapping systems (CANS). In doing so the cartographic alphabet is found. The map representation theory is tested against some of the most representatives CAMS in use today for the production of topographic maps and it is found general enough to accommodate the different characteristics of the system in use. The theory is used to evaluate the geometric part of the exchange standard of the National Committee for Digital Cartographic Data Standard (NCDCDS).
