Unfortunately, empirical research for the acquisition of cartographic knowledge is lacking, and forms a major impediment towards the development of a full-scale expert system. The main motivation for this research is to contribute to the acquisition and formalization of cartographic knowledge through a computer-assisted inventory of the Austrian National Topographic Map Series. The inventory includes settlement, transportation and hydrographic features from the same geographical region at 1:50,000, 1:200,000 and 1:500,000. Map feature information is archived using a relational database, to facilitate comparisons between map scales. Cartographic information acquired through queries of the relational database leads to the formulation of prototype rules. One set of rules describes the selection behavior of settlement, hydrography and transportation under changing map scale. A second set of rules expresses the degree of simplification for settlement objects through multiple scale. The possible influence of different building functionalities and regional types is taken into consideration as well. The interaction between different map domains or different map objects is formulated in a third set of rules. Some rules seem to be very obvious, others express very detailed information. Further comparative empirical studies, focused on the acquisition of cartographic knowledge, will throw light upon the usefulness of the inventory approach and the validity of prototype rules derived from it.
