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]
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]
The two main disciplines of geomechanics are soil mechanics and rock mechanics.Former deals with the soil behaviour from a small scale to a landslide scale. The latter deals with issues in geosciences related to rock mass characterization and rock mass mechanics, such as applied to petroleum, mining and civil engineering problems, such as borehole stability, tunnel design, rock breakage, slope ...
Both geomatics and geoinformatics include and rely heavily upon the theory and practical implications of geodesy and cartography. Geography and earth science increasingly rely on digital spatial data acquired from remotely sensed images analyzed by geographical information systems (GIS), [ 8 ] photo interpretation of aerial photographs, and Web ...
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
Geomatics engineering: The design, development, and operation of systems for collecting and analyzing spatial information about the land, the oceans, natural resources, and manmade features. Survey engineering; Geodesy; Geospatial; Information engineering: Generation, distribution, analysis, and use of information, data and knowledge in systems.
The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS.The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).
These conflicts can be reduced to a basic conflict between the need for more data on the map, and the need for less, with generalization as the tool for balancing them. One challenge with the information theory approach to generalization is its basis on measuring the amount of information on the map, before and after generalization procedures. [9]
