caption_attribution_description: English: The Bureau of Land Management has a unique mission within the Department of the Interior. It's the scope of our work that sets us apart. We manage activities ranging from outdoor recreation to livestock grazing, from mineral development and energy production to conservation of natural, historical and cultural resources. More than 10,000 employees across the nation take on the responsibility of protecting our resources and how they're used on public lands. Our people take an active role in serving the communities adjacent to our public lands. And we balance the country's population growth with its natural resources - a consistent source of new challenges for our creative employees to face. Get to know more about our multiple-use mission and where we work through these photos of #BLMcareers. Photo by BLM Oregon.
context_page_description: Surveying or land surveying is the technique, profession, art and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them. A land surveying professional is called a land surveyor. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as building corners or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales.
  Surveyors work with elements of geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. They use equipment, such as total stations, robotic total stations, theodolites, GNSS receivers, retroreflectors, 3D scanners, radios, inclinometer, handheld tablets, digital levels, subsurface locators, drones, GIS, and surveying software.
  Surveying has been an element in the development of the human environment since the beginning of recorded history. The planning and execution of most forms of construction require it.

  Surveying has been an element in the development of the human environment since the beginning of recorded history. The planning and execution of most forms of construction require it. It is also used in transport, communications, mapping, and the definition of legal boundaries for land ownership. It is an important tool for research in many other scientific disciplines.
