Feibing Benjamin Zhan, Barbara Pfeil Buttenfield · International Journal of Geographical Information Systems · 1995
Object-oriented schemes for representing and processing knowledge concerned with cartographic sy mbolization in GIS have been suggested by a number of researchers. As a sequel to these research efforts, the problem of object-oriented knowledge representation in the domain of symbol selection for visualizing spatial statistical information is addressed in this paper, and an operational system on this domain is presented. First, the domain knowledge is specified, and the decision process for symbol selection is formulated. Then the specified knowledge is represented and processed in an object-oriented manner. Implementation issues are discussed, and results are demonstrated with examples.
