A land surveyor assesses the surrounding landscape or terrain for any development project. They usually use specialized machinery and tools to do this as many of today’s development, building, subdivision, and tunnelling projects are quite complex. This intricacy and complexities combined with the sheer scale of some projects mean getting tremendously accurate surveying data. It is needed to make sure no mistakes take place. They work both on-field and at the office.

What do they use? Land contour surveys need modern gear such as theodolites with built-in electronic distance meters, to calculate and capture data.
