Practice is an important part of engineering surveying teaching. In addition to verifying classroom theory, it is also a link to consolidate and deepen the knowledge learned in the classroom, and it is also a means to cultivate students' practical ability and train strict scientific attitude and style. Through the establishment of control network, mapping of topographic points, hand mapping, etc., the concept of surveying and mapping ground points can be strengthened, and the ability to solve practical surveying problems in engineering can be improved
