大縮尺地図の類似系記号による分析とそのサブルーチン化

抄録

This paper describes a symbols used in large scale method of subroutinization mapping by personal computer. First, the legend of these maps were analyzed and a table of the various symbols applied in different large scale maps was made out according to the line or area of symbols, such as, circle, triangle and etcetera. Then the classification of symbol elements was tested by analyzing “similar type symbols”. Regarding to the symbol subroutinization process, the standards for fixed-form symbols used in legends of large scale maps were set and the subroutine for most symbols were produced. The result shows that this method can process the map symbols more efficiently.
