Triangulation station, the Glossary

A triangulation station, also known as a trigonometrical point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity.^[1]

Surveying and geodesy markers

Aerial photography

Aerial photography (or airborne imagery) is the taking of photographs from an aircraft or other airborne platforms.

See Triangulation station and Aerial photography

Benchmark (surveying)

The term benchmark, bench mark, or survey benchmark originates from the chiseled horizontal marks that surveyors made in stone structures, into which an angle iron could be placed to form a "bench" for a leveling rod, thus ensuring that a leveling rod could be accurately repositioned in the same place in the future. Triangulation station and benchmark (surveying) are surveying and geodesy markers.

See Triangulation station and Benchmark (surveying)

Benchmarking (hobby)

Benchmarking, also known as benchmark hunting, is a hobby activity in which participants find benchmarks (also known as survey markers or geodetic control points). Triangulation station and Benchmarking (hobby) are surveying and geodesy markers.

See Triangulation station and Benchmarking (hobby)

Bilby tower

A Bilby tower is a type of survey tower made from steel and used by the United States Coast and Geodetic Survey (USCG&S) from 1927 to 1984.

See Triangulation station and Bilby tower

Boundary marker

A boundary marker, border marker, boundary stone, or border stone is a robust physical marker that identifies the start of a land boundary or the change in a boundary, especially a change in direction of a boundary.

See Triangulation station and Boundary marker

Computer cartography

Computer cartography (also called digital cartography) is the art, science, and technology of making and using maps with a computer.

Coordinate system

In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

See Triangulation station and Coordinate system

Elevation

The elevation of a geographic ''location'' is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum).

See Triangulation station and Elevation

Geodesy

Geodesy or geodetics is the science of measuring and representing the geometry, gravity, and spatial orientation of the Earth in temporally varying 3D.

See Triangulation station and Geodesy

Global Positioning System

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force.

Laser

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
