Survey markers, also called survey marks, survey monuments, or geodetic marks, are objects placed to mark key survey points on the Earth's surface. They are used in geodetic and land surveying. A benchmark is a type of survey marker that indicates elevation ( vertical position ). Horizontal position markers used for triangulation are also known ...
Building Surveying emerged in the 1970s as a profession in the United Kingdom by a group of technically minded General Practice Surveyors.
