The current study examined the potential influence of existing spatial knowledge on the coding of new spatial information. In the Main experiment, participants learned the locations of five objects before completing a perspective-taking task. Subsequently, they studied the same five objects and five additional objects from a new location before completing a second perspective-taking task. Task ...

We pose the central problem of defining a measure of complexity, specifically for spatial systems in general, city systems in particular. The measures we adopt are based on Shannon's (in Bell Syst Tech J 27:379-423, 623-656, 1948) definition of information. We introduce this measure and argue that increasing information is equivalent to increasing complexity, and we show that for spatial distri...

Spatial judgments and actions are often based on multiple cues. The authors review a multitude of phenomena on the integration of spatial cues in diverse species to consider how nearly optimally animals combine the cues. Under the banner of Bayesian perception, cues are sometimes combined and weighted in a near optimal fashion. In other instances when cues are combined, how optimal the integrat...

This paper is a survey of research in Spatial Information Management. Research is reviewed from a variety of applicaLion areas, including Geographic systems, Computer Aided Design and Manufacturing, Image Processing, graphical interfaces to Data Base Management Systems, and general te chniques for the representation of spatial information. Significant issues are outlined, and areas suggested fo...

Land administration systems (LAS) are now challenged by new technologies and radically different demands for land information for modern governments. Spatial information is good enough to support spatial identification and location enablement applications available in every significant type of software (word processing, spread sheets, professional applications, Web systems, GIS and databases). ...

Admittedly the most crucial and the most neglected aspect of the spatial regression analysis, spatial contiguity remains an ambiguous concept that is largely dependent on the type of spatial units used and the characteristics of each application. The application of regression analysis to spatial data raises computational as well as conceptual issues. Computational issues consist in statistical ...

Spatial and spatial-temporal processes in the physical, environmental, and biological sciences often exhibit complicated and diverse patterns across different spacetime scales. Both scientific understanding, often reflected in computer models, and observational data vary in form and content across scales. We develop and examine a Bayesian hierarchical framework by which the combination of such ...

Spatial information associates properties to labeled areas. Space is partitioned into (elementary) parcels, and union of parcels constitute areas. Properties may have various level of generality, giving birth to a taxonomy of properties for a given universe of discourse. Thus, the set of properties pertaining to a conceptual taxonomy, as the set of areas and parcels, are structured by a natural...

For computer software, the semantics of spatial information is not a trivial issue. Due to the differences between human spatial cognition, reasoning, and communication, and its computerised counterpart, a number of difficulties persist in bringing the two paradigms together. While the qualitative way in which humans reason about space enables them to solve all kinds of spatial problems in thei...

Spatial representation has two contrasting but interacting aspects (i) representation of spaces’ and (ii) representation by spaces. In this paper we will examine two aspects that are common to both interpretations of the theme of spatial representation, namely nerve-type constructions and refinement. We consider the induced structures, which some of the attributes of the informational context a...
