Surveys of public lands

A survey is a method used to determine the relative positions of various objects on the land by measuring the horizontal distances between them. Briefly, a survey is a process of accumulation of data of various details related to land. The main objective of surveying land is to prepare maps to a suitable scale. Various types of maps such as topographical maps, cadastral maps, engineering maps, military maps, contour maps, geological maps, archaeological maps, and so on can be prepared by surveying.
