When you think about surveyors, you probably conjure up an image of someone standing on a road or parcel of land looking through some type of complicated surveying device. While land surveying is certainly one type of surveying, there are several other types and each type accomplishes a different but highly important task.
Engineering surveyors accomplish a multitude of important tasks. Before every road, house, bridge and skyscraper are built, surveyors are on the job measuring the grade and slope of the land, setting boundary lines and ensuring that the ground and foundations of structures are level. Roads must be graded and sloped properly in order to be safe, and a surveyor helps with this, as well. They use tools such as theodolites, clinometers, tripods, levels and sometimes a total station, which includes a theodolite and an electronic distance meter.
The tasks of engineering and land surveyors are somewhat similar, in that they both take precise land measurements. Land surveyors often help in the creation of maps, and mapping technicians are a type of surveyor that assists professional cartographers. This is a job that could take you to any area in the world to help create maps, and you will use the typical tools of a surveyor, including the theodolite.
The mining industry also relies on surveyors for several tasks. Generally, a mine surveyor probably has a degree in mining and mineral engineering. These surveyors create maps for where the mine should be located, and these are maps both for the surface and underground. Surveyors might be on hand all the time during a mining project to take daily records or to help make design or construction changes on an as-need basis. Those who earn a degree in mining will take classes such as mining engineering, geology, chemistry and metallurgy. Mining engineers use tools such as a total station, a phototheodolite and other photogrammetric instruments.
There are also surveyors who spend much of their time out on the water, taking down calculations and measurements for various sea, river and lake projects. These individuals are known as hydrographic surveyors, and they use high-tech software and electronic equipment to make calculations, as well as more basic tools such as a three-arm protractor and an alidade. These surveyors create detailed maps for navigation both above and below the water surface.
They also help with the construction of bridges over water, dredging operations, mining operations and the building of harbors, docks and piers. Surveyors are invaluable for water-related construction as they can ensure that projects are built safely and that they are securely anchored into the sea, river or lake floor.
