Data Collection



Metrology is the study and application of measurement. Distances between property corners, elevations on site topography surveys, footings of structural steel, and centerlines of pipes are objects that increase in value when measured.

Conventional measurement equipment includes steel pocket tapes and fiberglass reel tapes with distances collected in field books. One of the most accurate piece of equipment in our trucks is an autolevel used to project elevation data optically. We also use electronic distance measurers to emit light waves, reflect from survey prisms, and return a distance and angle for an electronic data collector to record. Measurements can also be collected from GNSS positioning equipment.

As site topo surveys increase in complexity to include mechanical and structural elements, conventional survey methods and GNSS data collection begins to weaken. Southern Survey uses high definition laser scanning to collect millions of points and measure in 3D world of XYZ dust.
