Meet a Professional Surveyor
History

|
Today’s surveyors use cutting-edge technology to collect and analyze data. High-precision GPS equipment, 3D laser scanning systems, robotic total stations, and intricate GIS hardware and software challenge surveyors to apply increasingly complex technology to measure and map our world.
Years ago, surveyors used chains, compasses, transits, and plumb bobs. Today, fieldwork often involves computerized measuring, GPS, and digital 3D scanning. The data is stored on a field laptop or electronic fieldbook and brought back to the office for processing and creating the map.
Sometimes a surveyor may work in the field and then deliver the data to a surveyor who works in the office. The office-based surveyor analyzes the data and creates the maps. Because most surveys become legal documents, all states require that licensed surveyors review and verify the data and resulting maps.
Within a few minutes a surveyor can digitally capture measurements of an entire shopping center using 3D scanning technology. This same technology is being used in the movie industry to create digital environments in which 3D characters can be placed, and in auto racing for the modeling of cars for aerodynamics.
