Surveying 101: A Look at the Science of Spatial Data

Surveying 101


Have you ever heard of a “bird’s eye” view? That’s what can be used to describe land surveying. Land surveying is the practice of utilizing professional equipment and mathematical calculations to replicate the terrain of any land surface. Surveying produces images that record the topography of a designated area. Surveying plays a key role in the planning and development of most construction projects.

Much like engineering, there are several different types of land surveying. Each type pinpoints a specific aspect of the surveying field. Every Professional Land Surveyor (PLS) should understand the works of different types of surveys. A few of the most common surveys include:

  • Standard land survey – determining property boundaries
  • Engineering survey – securing construction sites
  • Mapping survey – producing maps and chart analysis
  • Hydrographic survey – directing river routes for navigation purposes

While every type of surveying varies, all require some form of mathematical calculation. These calculations range from trigonometry to calculus, but all are essential to an accurate survey. It is important that surveyors understand several in-depth math concepts to complete a survey with ease. Some of the most important math concepts include:

  • Linear relationships
  • Bearings and azimuths
  • Logarithms and exponents
  • Pythagorean Theorem
  • Derivatives and integrals

Complicated calculations comes with complicated equipment. Professional Land Surveyors (PLS) are trained to manage top-notch land surveying equipment. These advanced technologies record accurate measurements and calculations with the click of a button. Some of the most common land survey equipment includes:

  • Theodolites
  • Measuring tapes
  • 3D scanners
  • Global Positioning System (GPS)
  • Aerial drones
