Knowra Surveying Surveying Surveying is the practice of determining positions, distances, angles, and elevations to map land and establish boundaries. Its measurements provide spatial control for construction, property records, and navigation.
Geodesy : The science of measuring Earth’s shape, gravity field, and changing position. Its Earth models provide the large-scale reference framework used by surveying.
Cadastral surveying : Surveying that defines, records, or re-establishes property boundaries. It applies measurement to land ownership and legal parcel descriptions.
Ancient Egyptian land surveying : The measurement and re-establishment of land parcels in ancient Egypt, especially after Nile floods. It illustrates surveying’s early role in restoring boundaries and assessing land.
Cartography : The practice and study of making maps. Cartography communicates spatial information, while surveying establishes its measured positions.
Land registration : The official recording of information about land ownership, rights, and boundaries. Surveyed parcel descriptions make registered property boundaries identifiable on the ground.
Total station : An electronic surveying instrument that measures angles and distances to determine point coordinates. It combines angle and distance measurements for precise field mapping.
Topographic surveying : Surveying that records terrain elevations and natural or built features. Its maps show the ground and features that guide design and planning.
Roman land surveying : The Roman practice of measuring and dividing land for roads, settlements, and property. Roman surveyors applied organized measurement to large-scale administration and infrastructure.
Remote sensing : The acquisition of information about objects or areas without physical contact, usually by sensors. It often maps broad areas from a distance rather than measuring points directly on site.
Boundary dispute : A disagreement over the location or ownership of a boundary between properties. Survey evidence can clarify competing interpretations of boundary descriptions.
