Land surveyors work to determine the exact boundaries of pieces of land. The information they provide is relevant to the contours of land surfaces, and the information is used for map-making, construction and engineering.
Surveyors provide information that pertains to the property lines of land to determine the exact locations of construction projects and real estate. A piece of property may need to be surveyed when a house is purchased or surveyed when there's an issue with boundary disputes. Construction projects typically require land surveyors to determine the locations of buildings and roadways. Survey maps show changes to property lines and show any restrictions that come attached to the properties, such as how large and exactly what type of structure is allowed on a property.
When working to make the determinations, a surveyor measures the distances and angles between points that are below, above or on the surface. A surveyor uses land titles, survey records and land records make his determinations, and he searches for evidence of previous boundaries to determine where the lines are located. A land surveyor records results of his information and verifies the accuracy of the data he has collected. He prepares maps, reports and plots, and he presents his information to government entities or his clients.
