Geodesy or geodetics [1] is the science of measuring and representing the geometry, gravity, and spatial orientation of the Earth in temporally varying 3D.It is called planetary geodesy when studying other astronomical bodies, such as planets or circumplanetary systems. [2]
A surveyor's shed showing equipment used for geomatics. Geomatics is defined in the ISO/TC 211 series of standards as the "discipline concerned with the collection, distribution, storage, analysis, processing, presentation of geographic data or geographic information". [1]
Geomatics; Geovisualization "Geospatial technology" may refer to any of "geomatics", "geomatics", or "geographic information technology." The above is in addition to other related fields, such as: Cartography; Geodesy; Geography; Geostatistics; Photogrammetry; Remote sensing; Spatial data analysis; Surveying; Topography
There are several other terms, often used interchangeably with technical geography to subdivide the discipline, including "techniques of geographic analysis," [69] "Geographic Information Technology," [1] "Geography method's and techniques," [70] "Geographic Information Science," [71] "geoinformatics," "geomatics," and "information geography".
Geomatics includes geodesy (scientific discipline that deals with the measurement and representation of the earth, its gravitational field, and other geodynamic phenomena, such as crustal motion, oceanic tides, and polar motion), cartography, geographical information science (GIS) and remote sensing (the short or large-scale acquisition of ...
Geographic information science (GIScience, GISc) or geoinformation science is a scientific discipline at the crossroads of computational science, social science, and natural science that studies geographic information, including how it represents phenomena in the real world, how it represents the way humans understand the world, and how it can be captured, organized, and analyzed.
A wooden tripod holding an optical level is set up firmly on the ground. Levelling or leveling (American English; see spelling differences) is a branch of surveying, the object of which is to establish or verify or measure the height of specified points relative to a datum.
Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length.. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude.
