From Wikipedia, the free encyclopedia. Time geography or time-space geography is an evolving transdisciplinary perspective on spatial and temporal processes and events such as social interaction, ecological interaction, social and environmental change, and biographies of individuals.

The space-time prism itself is an extension of the space-time path. However, the prism does not trace the observed movements through space of an individual over an interval of time; instead it shows what portions of space are possible for an individual to be in at specified times.

The space-time prism (STP) is the envelope of all possible space-time paths between two anchor locations with known departure and arrival times respectively. STPs are measures of space-time path uncertainty when a moving object’s locations are undersampled with respect to time (Pfoser and Jensen 1999).

Two central concepts in time geography are the space–time path and prism. The path represents actual mobility (real or simulated) and the prism represents potential mobility in space with respect to time.

Time–space compression (also known as space–time compression and time–space distanciation), articulated in 1989 by geographer David Harvey in The Condition of Postmodernity, refers to any phenomenon that alters the qualities of and relationship between space and time.

1 Definitions and Uses. Spatial interaction is the general term for any movement of people, goods, or information over space that results from a decision-making process.

Spatial interaction models seek to explain existing spatial flows. As such it is possible to measure flows and predict the consequences of changes in the conditions generating them. When such attributes are known, it is possible to better allocate transport resources such as conveyances, infrastructure, and terminals.

The spatial pattern of a distribution is defined by the arrangement of individual entities in space and the geographic relationships among them. The spatial pattern can be characterized by the behavior of the correlogram’s wavelength and amplitude within a specific range of spatial orders.

Abstract. Spatial interaction is a basic concept that considers how locations interact with each other in terms of the movement of people, freight, services, energy, or information. Complementarity, intervening opportunity, and transferability are the three bases for spatial interactions.

Spatial interaction is the flow of products, people, services, or information among places, in response to localized supply and demand. It is a transportation supply and demand relationship that is often expressed over a geographical space.

The Gravity Model holds that the interaction between two places can be determined by the product of the population of both places, divided by the square of their distance from one another. The primary implication of this model is that distance is not the only determining factor in the interaction between two cities.

The Multiple-Nuclei Model does still provide a good interpretation of the land-use organization of today using multiple nodes to illustrate how the urban land is used. The CBD is no longer at the center of the action, but multiple business districts develop to support the outlying areas of the city.

The gravity model can also be used to compare the gravitational attraction between two continents, two countries, two states, two counties, or even two neighborhoods within the same city. The functional distance can be the driving distance or can even be flight time between cities.

Spatial interaction is the flow of information, products, and human beings from one location to another. Three principles of spatial interaction, as proposed by transportation geographer Edward Ullman, are complementarity, transferability, and intervening opportunity.

SPATIAL INTERACTION IS A dynamic flow process from one location to another. A workplace such as a factory or office tower is an example of a place with a demand for labor, while a residential neighborhood provides a source of workers.

A spatial interaction model is a mathematical model that predicts the movement of people between origins (usually their homes) and destinations (health facilities) by examining the distance between them. Such models are one of the more complex ways of deciding where to locate a new health facility.

Definition. A distribution or set of geographic observations representing the values of behaviour of a particular phenomenon or characteristic across many locations on the surface of the Earth.

Dispersion or distribution patterns show the spatial relationship between members of a population within a habitat. Individuals of a population can be distributed in one of three basic patterns: uniform, random, or clumped.

A common example of spatial data can be seen in a road map. A road map is a two-dimensional object that contains points, lines, and polygons that can represent cities, roads, and political boundaries such as states or provinces. A road map is a visualization of geographic information.

On the spatial distribution of development: The roles of nature and history. Economists point to three factors to explain how population is distributed: geographical characteristics, agglomeration, and history.

Here, are three main ways to describe the spatial pattern of object:

• Clustered: occurs when objects exist in close proximity to one another.
• Dispersed: occurs when objects exist in approximately equal distances from one another.
• Random: occurs when objects exist in neither a clustered or dispersed pattern.

A spatial distribution study works by selecting a variable and plotting incidents of that variable on a map. For example, imagine that you wanted to know which neighborhoods in a town were the most expensive. Cost is your variable, so you assign colors to different values.

the arrangement of items on the earth’s surface (analyzed by the elements common to all spatial distributions: density, dispersion, and pattern.)

Recognize spatial patterns in their environment….Below, nine changes commonly found in spatial patterns are listed.

1. Size Change.
2. A Rotation.
3. Shading Change.
4. Shape Change.
5. Position Switch.
6. Key Part Vanishes or Appears.
7. Position Change.

GIS Fundamentals Chapter 1: An Introduction Exercises 1.1 – Why are we more interested in spatial data today than 100 years ago? Mostly because as human populations have continued to increase, our need to more effectively and efficiently use our resources has become more crucial than ever.

The supported spatial element types are points, line strings, and polygons. For example, elements might model star constellations (point clusters), roads (line strings), and county boundaries (polygons). Each coordinate in an element is stored as an X,Y pair.

1 : characterized by or given to the expression of opinions very strongly or positively as if they were facts a dogmatic critic.

Conclusion: Dogmatism is one of the factors that have a negative effect on wellbeing. Religious dogmatism is the most dangerous factor against wellbeing. Dogmatic individuals have an inflexible cognitive system that emerges as a stable personality trait and decreases their adjustment with environment.

The definition of dogmatic is the strong expression of opinions as if they were facts. An example of dogmatic is insisting that a feminist view is the one and only way to look at literature.
