A simple boundary survey can take 2 to 3 days, whereas extensive topographic or drone mapping for large acreage can take 1 to 2 weeks of field and post-processing work.

Standard GPS provides accuracy of about 3 to 10 meters, while DGPS (Differential GPS) uses a stationary base transmitter correction system to achieve millimeter-level real-time kinematics (RTK) accuracy.

GPR uses high-frequency radio waves to detect buried objects such as conduits, concrete voids, pipelines, and historical foundations without requiring disruptive excavation.
