Basic surveyance has occurred since humans built the first large structures. The prehistoric monument at Stonehenge (c. 2500 BC) was set out by prehistoric surveyors using peg and rope geometry.[1] In ancient Egypt, when the Nile River overflowed its banks and washed out farm boundaries, boundaries were re-established by a rope stretcher, or surveyor, through the application of simple geometry. The nearly perfect squareness and north-south orientation of the Great Pyramid of Giza, built c. 2700 BC, affirm the Egyptians' command of surveying. The Groma surveying instrument originated in Mesopotamia (early 1st millennium BC).[2] Under the Romans, land surveyors were established as a profession, and they established the basic measurements under which the Roman Empire was divided, such as a tax register of conquered lands (300 AD).[3] In England, the Domesday Book, commissioned by William the Conqueror in 1086 recorded the names of all the land owners, the area of land they owned, the quality of the land, and specific information of the area's content and inhabitants, although it did not include maps showing exact locations. |
