GPS surveys use portable receiving antennas to gather data transmitted from satellites which are used to calculate the position of the object being located on the surface of the earth. The receiving antennas can be miles apart and still obtain very accurate data. GPS surveys are used to establish coordinate control points for the State Plane Coordinate Systems, large boundary surveys, and subdivision surveys. It can also be used to collect data for Geographic Information Systems / Land Information Systems (GIS/LIS), such as the location of streets, homes, businesses, electric, phone & gas utilities, water & sewer systems, property lines' soil & vegetation types, water; courses, etc. This data can be used in future planning, preservation and development.
