CASS topographic mapping is a compulsory course and a necessary skill for students majoring in Survey-ing and Mapping Engineering.To efficiently and accurately evaluate and score the quality of the topographic map drawn by the students,based on the secondary development of CAD by using the VB program,by setting the CASS standard reference topographic map and comparing with the topographic map drawn by the students,the dif-ference in entity code matching and coordinate position matching between the two are compared.By combining the score allocation rules of various terrain entities,the automatic scoring of the entire topographic map is ultimately achieved.Compared to traditional manual scoring methods,automatic scoring methods have some advantages in ef-ficiency and accuracy.The research results are of some help to the teaching of Surveying and Mapping courses and students'practical ability evaluation.
