When driving down the road onto the highway or past a potential construction site, there is often a person with an “odd-looking camera.” Unbeknownst to many is that these people are known as land surveyors.
Land surveyors map out and document particular areas' physical and geospatial boundaries to zone projects for construction companies and government agencies. Land surveyors also help solve land disputes with their mathematical and technical knowledge.

They are additionally capable of creating, understanding, and interpreting maps. Land surveyors use a tool called a theodolite, the “odd-looking camera,” to measure the angle between two points, a.k.a benchmarks.
Old-fashioned land surveyors used tape measurers, or other measuring tools, along with theodolites and trigonometric know-how, to triangulate the location of points. In general, digital technology has completely changed the way land surveyors do their jobs. Digital theodolites, also known as total stations, calculate and record distances and angles through reflection.
Taking the information recorded from the total station, land surveyors can use computer-aided design (CAD) software to create 3D map models. Thanks to developments in land surveying, land disputes can be solved with less hassle, and homes can be developed more efficiently.
