Proximity operators for qualitative spatial reasoning,easures. These operators appear to be semi-quantitative in nature as opposed to purely qualitative. In the light of observations drawn from psychometric testing of perceived proximity, this paper discusses how a model to support proximal reasoning could be constructed. The relationships between the

Qualitative distances,ept of “distance systems” consisting of a list of distance relations and a set of structure relations that describe how the distance relations in turn relate to each other. The framework is characterized by making the role of the “frame of reference” explicit, which captures contextual information e

,Structural analysis of geographic information and GIS operations from a user’s perspective,ormation and operations with direct mappings to users‘ conceptual schemata and analytic needs. As a result, GIS data and operations tend to be system-dependent and switch from one system to another is not trivial. Since the conceptual schemata for structuring both declarative and procedure knowledge

A loosely coupled interface to an object-oriented geographic database,etween two major tools: spatial query language and graphical interface. This paper addresses the problem of building an interactive querying system for spatial databases with an open architecture. We focus on the following issues: (i) design of a database-independent Graphical User Interface (GUI) p

Attempts to use systems based on explicit knowledge representation (e.g., rule-based or expert systems) also had relatively little success. The major limiting factor to explicit knowledge systems in generalization is the scarcity of

Spectral representations of linear features for generalisation,. Such representations are developed from spectral tools: Fourier series and wavelet decomposition. The theoretical possibilities of representations are discussed from a generalisation point of view. Algorithms are built on these representations. The experiments are presented and discussed, particul
