Remote sensing is the acquisition of information about an object or phenomenon ... geography, land surveying and ... glaciology, geology). It also has military ...
Richat Structure by Shuttle Radar Topography Mission (SRTM). Instead of being a meteorite impact, the landform is more likely to be a collapsed dome fold structure.. Remote sensing is used in the geological sciences as a data acquisition method complementary to field observation, because it allows mapping of geological characteristics of regions without physical contact with the areas being ...
Technical geography is the branch of geography that involves using, studying, and creating tools to obtain, analyze, interpret, understand, and communicate spatial information. [1][2][3][4] The other branches of geography, most commonly limited to human geography and physical geography, can usually apply the concepts and techniques of technical ...
Geomatics includes the tools and techniques used in land surveying, remote sensing, cartography, geographic information systems (GIS), global navigation satellite systems (GPS, GLONASS, Galileo, BeiDou), photogrammetry, geophysics, geography, and related forms of earth mapping. The term was originally used in Canada but has since been adopted ...
A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. [1][2] Much of this often happens within a spatial database; however, this is not essential to meet the definition of a GIS. [1] In a broader sense, one may consider such a system ...
There are five types of resolution when discussing satellite imagery in remote sensing: spatial, spectral, temporal, radiometric and geometric. Campbell (2002) [ 6 ] defines these as follows: Spatial resolution is defined as the pixel size of an image representing the size of the surface area (i.e. m 2 ) being measured on the ground, determined ...
Geoinformatics has at its core the technologies supporting the processes of acquisition, analysis and visualization of spatial data. Both geomatics and geoinformatics include and rely heavily upon the theory and practical implications of geodesy. Geography and earth science increasingly rely on digital spatial data acquired from remotely sensed ...
Geology employs many of the tools and techniques of technical geographers, such as GIS and remote sensing to aid in geological mapping. [124] However, geology includes research that goes beyond the spatial component, such as the chemical analysis of rocks and biogeochemistry. [125]
