Research Abstract

It is necessary to develop a system by which information included in maps is recognized individually in order to constitute the grographical information system (GIS). In this study map symbols which are symbolized in the map information are taken as basic symbols and extracted. Moreover their charcteristic quantities are researched and the main elements by which map symbols can be recognized are extracted from the elements to constitute the map symbols. The results obtained from the research described above can be concluded as follows :
(1) From the standpoint to recognize the map symbols, the concept that one image constitutes one symbol is ruled out and the concept that multi-image constitutes one symbol is introduced here.
(2) a^-j ten kinds of recognition elements are extracted when one image constitutes one sumbol, while w^-z four kinds of recognition elements are extracted when multi-image constitutes one symbol.
(3) The criterion of classification can be decided by calculating the threshold and range of every element to recognize map symbols based on 14 kinds of recognition elements.
