[0002] Surveying and mapping literally means measuring and drawing. It is based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with global navigation satellite positioning system (GNSS), remote sensing (RS), and geographic information system (GIS) as the technical core. It selects existing feature points and boundaries on the ground and obtains graphics and location information reflecting the current situation of the ground through measurement methods for the use of engineering construction, planning and design, and administrative management. Surveying and mapping refers to the measurement, collection, and drawing of the shape, size, spatial position, and attributes of natural geographical elements or artificial facilities on the surface. In construction projects such as houses, roads, and bridges, surveying and mapping is completed through the use of surveying and mapping, which facilitates the acquisition of various data for drawing maps.
