[0002] In civil engineering, surveying and mapping technology plays a vital role, and its application is extensive and critical. Surveying and mapping technology provides accurate geometric and geospatial data for civil engineering surveys, helps engineers draw detailed topographic maps, geological maps and geomorphological maps, and lays the foundation for engineering design. This information is used to determine the feasibility of the project, road line selection, bridge design and water conservancy facility planning. In the process of engineering surveying and mapping, surveying telescopes are usually used to test the distance between buildings.
