Detailed Description
An emergency map making method based on a map making scheme set comprises the following steps:
s1, establishing a drawing symbol library, wherein the drawing symbol library comprises symbols of point, line and surface element configuration under various drawing scenes; and establishing a drawing rule base which contains drawing rules under various drawing scenes.
The dot, line and surface elements, namely dot symbols, linear symbols and surface symbols, are prepared according to the requirements in the graphic software and stored to form a symbol library. The drawing rule base refers to various drawing rules in the summarized drawing process, and the drawing rules are stored in a database to form the drawing rule base.
