Accurate and vivid depiction of contour lines is a key issue in map drawing.This paper focused on potential types of inconsistencies that may arise between contour lines and elevation annotation points during map production,and introduced an irregular triangulation network inspection method and a radiating inspection method based on both contour lines and elevation annotation points,in order to provide practical guidance for production workflows.Leveraging the ArcEngine component library and the C#programming language,a contour quality inspection software was developed,with its accuracy validated using real sample data.The findings indicate that the construction of an irregular triangulation network using contour line nodes effectively detects point-line inconsistencies with a high degree of precision,meeting the requirements of project production.
