DRAWING SYSTEM AND METHOD FOR PREPARING DIGITAL MAP USING THE SAME

摘要

PURPOSE: A numerical map system is provided to reduce the error rate and the consumption time of manufacturing a numerical map. CONSTITUTION: A numerical map system comprises: A polygon calculating module(100), a polygon module(200), and a polygon control module(300). The basic building size and the basic polygon size are inputted to the polygon calculating module, and the polygon calculating module produces the minimum polygon size according to the boundaries of the specific building, compared to the basic building size. The polygon module determines the number of independent polygon of the specific building corresponding to the minimum polygon size of the specific building. The polygon control module controls the degree of precision by limiting the number of independent polygon of the specific building, and saves the independent polygon of the creation of the final building.
