What is surveying?
Surveyors' work includes taking measurements to accurately determine the location of points anywhere in the world. This location data is essential information for understanding land and the environment.
There are many specialist types of surveying:
- Boundary surveying – needs a licensed registered surveyor.
- Engineering surveying – working on major infrastructure projects like roads and railways.
- Geodetic surveying – defining the mathematical models of the Earth.
