Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To attain a well-modulated powerful map expression corresponding to variations of geographical features by writing stippling line segments according to variations in inclination of the geographic features. SOLUTION: A central segment to be processed is selected from a geographic surface, and 3×3 making 9 pieces of minute segments A surrounding the central segment are designated. Central segments are sequentially designated to the right in order from a central segment 22. Next, altitudes of the central segment 22 and the minute segments 11-33 are determined and compared with each other. If the altitude of the minute segment 33 is lowest, it is checked whether or not a pre-determined reference altitude is located between the altitudes of the minute segment 22 and the maximum inclination segment 33. If it is located in-between, a next minute segment 23 to be processed is designated. If not located in-between, a stippling line segment (a) is written from the central segment 22 to the minute segment 33.  In a small inclination part, the stippling segments continue and a line segment going in a stream line direction appears, while, in a large inclination part, the stippling line segments appear in scattered points or grains, and thus, a map in a well-modulated powerful expression is attained.
