People have been conducting land surveys for centuries. Determining property boundaries is important because it tells property owners where their responsibilities and benefits begin and end. Property owners have often argued and fought complicated legal battles over ownership of water, trees, and underground resources like oil. It is a land surveyor's job to determine where property lines are drawn and who has ownership of the land in certain areas.
Until recently, surveying land was done almost entirely by people with measuring equipment like tape and chains which were stretched across property.
