In this modern era, we are using high technology to complete the job whether in the field or office for data processing. High technology instrument such as GPS PROMARK 500 can provide up to millimeter (mm) level accuracy for land survey purposes. Besides of GPS PROMARK 500, we are still using total station for a certain places where the GPS cannot get a good signal.
