5. Total Station and GPS Surveying
Total Station and GPS surveying are essential modern techniques that enhance the precision and efficiency in geospatial data acquisition for civil engineering and Geo-Informatics fields. A Total Station combines an electronic theodolite, EDM, and microprocessor to capture accurate angle and distance measurements. Meanwhile, GPS allows for precise geolocation through satellite networks, applicable in various surveying methods. Furthermore, integrating these technologies optimizes performance and accuracy across diverse applications.
