Geolibertarianism Geolibertarianism (also geoanarchism) is a libertarian political philosophy that holds, like other forms of libertarian individualism, that each individual has an exclusive right to the fruits of his or her labor, as opposed to this product being owned collectively by society or the community. In other words, geolibertarians support private property.
Geolocation Geolocation is the real-world geographic location of an Internet connected computer, mobile device, or website visitor based on the Internet Protocol address, MAC address, hardware embedded article/production number, embedded software number (such as EXIF/IPTC/XMP or modern steganography), invoice, or other, perhaps self-disclosed, information.
Geolocation software In computing, geolocation software is used to deduce the geolocation (geographic location) of the other party, for example on the internet. One simple approach to geolocation is looking at the IP address and determining what country, organization, or user it has been assigned to, and guessing the user's location based on that.
Geologic fault Geologic faults, fault lines or simply faults are planar rock fractures, which show evidence of relative movement. Large faults within the Earth's crust are the result of shear motion and active fault zones are the causal locations of most earthquakes.
Geologic joint A joint is a generally planar fracture formed in a rock as a result of extensional stress. Joints are distinct from faults because joints do not have any significant offset of strata either vertically or horizontally.
Geologic map A geologic map is a special-purpose map made to show subsurface geological features. In the United States, geologic maps are usually superimposed over a topographic map (and at times over other base maps) with the addition of a color mask with letter symbols to represent the kind of geologic unit, stratigraphic contour lines, fault lines, strike and dip symbols, and various additional symbols as indicated by the map key.
Geologic modelling Geologic modelling (or modeling) is the applied science of creating computerized representations of portions of the Earth's crust, especially oil and gas fields and groundwater aquifers. In the oil and gas industry, realistic geologic models are required as input to reservoir simulator programs, which predict the behavior of the rocks under various hydrocarbon recovery scenarios.
Geologic preliminary investigation A geologic preliminary investigation is a survey of the subsoil conducted by an engineering geologist in conjunction with a civil engineer.

Geology of Victoria The Australian state of Victoria rests at the southern end of the Great Dividing Range, which stretches along the east coast and terminates near Ballarat. Nearby and fairly distinct, the Grampians may be considered to be the final part of the range.
Geomagnetic excursion A geomagnetic excursion, like a geomagnetic reversal, is a significant change in the Earth's magnetic field. Unlike reversals however, an excursion does not change the large scale orientation of the field, but rather represents a dramatic, typically short-lived decrease in field intensity.
Geomagnetic reversal A geomagnetic reversal is a change in the orientation of Earth's magnetic field such that the positions of magnetic north and magnetic south become interchanged. These events, which are believed to last a few hundred to a few thousands years, often involve an extended decline in field strength followed by a rapid recovery after the new orientation has been established.
Geomagnetic storm A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere. Associated with solar coronal mass ejections (CME), coronal holes, or solar flares, a geomagnetic storm is caused by a solar wind shock wave which typically strikes the Earth's magnetic field 24 to 36 hours after the event.

Geomancy Geomancy (from Old French geomancie <Late Latin geĹŤmantia <Late Greek geĹŤmanteia< geo, "earth" + manteia, "divination") from the eponymous ilm al-raml ("the science of sand"), is a method of divination that interprets markings on the ground, or how handfuls of dirt land when someone tosses them. The Arabic tradition consists of sketching sixteen random lines of dots in sand.

Throughout 20th century art historical discourse, critics and artists working within the reductive or pure strains of abstraction have often suggested that geometric abstraction represents the height of a non-objective art practice, which necessarily stresses or calls attention to the root plasticity and two-dimensionality of painting as an artistic medium.
Geometric algebra A geometric algebra is a multilinear algebra with a geometric interpretation. (The term is also used in a more general sense to describe the study and application of these algebras: Geometric algebra is the study of geometric algebras.

It is appropriate to mathematical modelling of some phenomena in financial markets.
Geometric continuity Geometrical or geometric continuity, was a concept of geometry primarily applied to the conic sections and related shapes by mathematicians such as Leibniz, Kepler, and Poncelet. The concept was an early attempt at describing, through geometry rather than algebra, the concept of continuity as expressed through a parametric function.
