How Does Land Surveying Work?

Have you ever seen someone in a hardhat with a tripod and strange-looking stick standing by the side of a road or property? If so, you probably wondered what that person was doing. Well, wonder no more. That person was most likely a land surveyor, and he or she was probably taking a variety of precise measurements with specialized surveying equipment to determine exactly where property boundary lines were located.

Land surveyors use high-tech equipment and good old-fashioned mathematics to create maps and measurements of land. If you’re wondering why such a service is needed, you may be surprised to find out that almost every property development project begins with a survey. Here’s what you should know about this important service.

Land Surveying Processes

Person using Surveing Equipment

Land surveyors may have slightly different processes, depending on the specific type of surveying they do. Here’s a quick overview of the various land surveyor types and the basic processes they go through to do their jobs:

  • Construction or Engineering: This type of surveyor studies changes in property lines and identifies the location of buildings and roads with exactness. They may also survey road topography and grade or determine the appropriate depth for building foundations.
  • Geodetic: A surveyor who uses satellite and aerial imaging to measure very large portions of the earth is called a geodetic surveyor.
  • Boundary or Land: This type of surveyor fulfills the important duty of determining exactly where properly lines are located.

There are other types as well, but these are some of the most common. Surveyors must stand by their work and are required to produce accurate numbers. Fortunately, land surveyor tools make it easier for these professionals to have a high degree of confidence in their calculations.



Tools Required

Surveyor demand is expected to grow over 10% between 2016 and 2026, according to the Bureau of Labor Statistics. The median annual wage is around $60,000 for surveyors who work for engineering or architectural firms and approximately $70,000 for government contractors. If you’re interested in pursuing this career path, you’ll need to receive appropriate training and education. You’ll also need the right survey instruments, which include a theodolite and a level (sight level, laser level and/or water level). A theodolite is the ultimate surveying tool and measures vertical and horizontal angles between points. Advanced theodolites can also measure distance.
