 Spatial Prediction
Spatial prediction, in general, is any prediction method that incorporates spatial dependence.
In fields such as petroleum exploration, mining, and water pollution analysis, data are available at specific spatial locations (such as experimental stations positioned above the ground or at certain distances in the air), and the goal is to predict unsampled locations.
The unsampled locations are often mapped on a regular grid, and the predictions are used to produce surface plots or contour maps.

 Spatial Intelligence
Spatial ability is also "the more abstract intelligence of a chess master, a battle commander, or a theoretical physicist" (194), as well as the familiar ability to recognize objects, faces, and details.
It is in the spatial intelligence that Gardner locates one of the activities most central to writing: the "ability to discern similarities across diverse domains." He praises Lewis Thomas's expressive analogies between biological phenomena and human concerns.
Gardner's account of the spatial intelligence touches upon another ability that is crucial to good writing: the ability to convey a sense of the "whole" of a subject or of a piece of writing--a "gestalt" organization, different from the logical-mathematical kind of organization used, for example, in this article.

The Spatial Test Battery (STB), developed by researchers at the Johns Hopkins University Center for Talented Youth, is a collection of subtests that assess various types of visual-spatial ability.
Spatial ability has long been recognized as a factor contributing to success in mathematics, natural sciences, engineering, architecture, and other fields of study.
Individuals with highly developed spatial ability, those who can see patterns in what appears to be confusion to others, will become more and more in demand in the fields of medicine, physics, engineering, mathematics, statistics, economics, and even finance.

 Vector (spatial) - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-11-07)
A common example of a vector is force — it has a magnitude and an orientation in three dimensions (or however many spatial dimensions one has), and multiple forces sum according to the parallelogram law.
Informally, a vector is a quantity characterized by a magnitude (in mathematics a number, in physics a number times a unit) and a direction, often represented graphically by an arrow.
If a vector is itself spatial, the length of the arrow depends on a dimensionless scale.

 Spatial Logics   (Site not responding. Last check: 2007-11-07)
Spatial logics are specification logics for describing the behavior and spatial structure of concurrent systems.
Logics for concurrent systems are certainly not new, but the intent to describe spatial properties, and in particular the spatial structure of distributed and mobile systems, seems to have arisen only recently.
The spatial properties we consider are essentially of two kinds: whether a system is composed of two or more identifiable subsytems, possibly including hierarchies of named locations, and whether a system restricts the use of certain resources to certain subsytems.

 Spatial Hypertext: An Alternative to Navigational and Semantic Links
Spatial hypertext has contributed to a number of these lines of hypertext research: playing into the discussion of hypertext literary theory; framing the discussion of visualization and interaction techniques for hypertext information; challenging the open-hypermedia research community with a different model of hypertext; and motivating work on Web workspaces.
The representational malleability of spatial hypertext is also considered important; early critiques of the rhetoric of hypertext call for a need to reform the established structural rigidity of hypertext and move to a more exploratory one [Moulthrop 1991].
Spatial hypertext, because of the lack of links or other explicit relationships between nodes, challenges the open-hypermedia research protocols to consider information structuring at a more abstract level [Nürnberg 1999].

 Vector (spatial) Info - Encyclopedia WikiWhat.com   (Site not responding. Last check: 2007-11-07)
Although the word now has many meanings (see also vector, and generalizations below), its original and most common meaning in those fields is a quantity that has a close relationship to spatial directions.
Often informally described as an object with a "magnitude" (size) and "direction", a vector is more formally defined by its relationship to the spatial coordinate system under rotations.
Such a vector is a special case of a tensor and is also analogous to a four-vector in relativity (and is sometimes therefore called a three-vector in reference to the three spatial dimensions, although this term also has another meaning for p-vectors of differential geometry).

 Spatial Audio Work in the GVU MCG   (Site not responding. Last check: 2007-11-07)
Spatial audio is sound that has been processed to give the listener a sense of the location of a virtual sound source and the characteristics of a virtual listening space.
Spatial audio can be useful whenever a listener is presented with multiple auditory streams, requires information about the positions of events outside of the field of vision, or would benefit from increased immersion in an environment.
For example, spatial audio may be limited to those applications for which a user is already wearing some sort of headgear, or for which the advantages of spatial sound outweigh the inconvenience of a headset.

This initiative had as its broad aim the development of an appropriate fundamental theory of spatial relations using natural language and mathematics, based on the formalization of geometric concepts as they are used in GIS and the cognitive aspects of spatial relations.
The three primary components of the research framework include: theories of individual and organizational behavior (particularly their relevance in understanding impediments and incentives to the sharing of information); the arenas among which sharing of spatial data occurs, could occur, or could be enhanced; and observations of the process of spatial data sharing in existing settings.
