Spatial intelligence with spatial statistics
2010 18th International Conference on Geoinformatics, 2010With the advent of Web 2.0, new technologies for spatial data service, and demanding needs in spatial data sharing, and advanced analysis, both geographic information system and spatial statistics are facing challenges from different disciplines never met before. Due to their mutual beneficial roles in highlevel decision making, it's quite essential to

Spatial Representations Without Spatial Computations
Psychological Science, 2022Cognitive maps are assumed to be fundamentally spatial and grounded only in perceptual processes, as supported by the discovery of functionally dedicated cell types in the human brain, which tile the environment in a maplike fashion. Challenging this view, we demonstrate that spatial representations—such as large-scale geographical maps—can be as well ...

Spatial and spatial-frequency primitives in spatial-interval discrimination
Journal of the Optical Society of America A, 1985Thresholds for spatial-interval discrimination were determined under conditions designed to introduce randomness in the spatial-frequency content of the stimuli from trial to trial. Neither a random scaling of the display nor the addition of flanking bars at varying distances affected the observer's ability to judge the relative interval between pairs ...

ON SPATIAL PERIODIC ORBITS AND SPATIAL CHAOS
International Journal of Bifurcation and Chaos, 2003This paper introduces an analytical method for constructing spatial periodic orbits of specified periods. This result is then extended to generating spatial chaos in the sense of Li and Yorke.

Spatial Interaction and Spatial Autocorrelation
2008The objective is to combine insights from two research traditions, spatial interaction modelling and spatial autocorrelation modelling, to deal with the issue of spatial autocorrelation in spatial interaction data analysis. First, the problem is addressed from an exploratory perspective for which a generalisation of the Getis–Ord G statistic is ...

ON SPATIAL LYAPUNOV EXPONENTS AND SPATIAL CHAOS
International Journal of Bifurcation and Chaos, 2003In this paper, we investigate the periodic orbits, spatial Lyapunov exponents, and stability of spatially periodic orbits of the general 2D Logistic system [Formula: see text] where a is a real constant and μ is a parameter. The existence of spatial chaos in the sense of Li and Yorke is proved using the Marotto theorem.

Spatial Pricing, Spatial Rents, and Spatial Welfare
The Quarterly Journal of Economics, 1982This paper presents a model of spatial equilibrium that integrates elements of spatial pricing and ThA¼nen location models. Properties of equilibrium under mill, uniform, and discriminatory pricing regimes are explored. Three comparative propositions concerning firm, consumer, and landowner welfare that obtain under the alternative pricing schemes are ...

ACM SIGMOD Record, 2000
This paper discusses issues related to the integration of spatial operators into the new generation of SQL-like query languages. Starting from spatial data models, current spatial extensions of query languages are briefly reviewed and research directions are highlighted.
