In the process of making a traffic map,it is usually necessary to draw the information of point position,point number,four to and so on on the published national(provincial and municipal)electronic traffic map.In or-der to improve the drawing efficiency of the traffic map,this paper combines the world map of the National Geo-graphic information public service platform,uses Python language,control point coordinate information,and automat-ically cuts the base map conforming to its template size in batches.The results show that compared with the tradi-tional manual cutting method,this method can reduce the manual workload,improve the working efficiency,stand-ardize the size of the traffic map and simplify the cutting process.
