Computation with imprecise geospatial data

TL;DR: In this article, the authors argue that current stand-alone and various loose/tight coupling approaches for integrating GIS with hydrological modeling are essentially technology-driven without adequately addressing the conceptual problems involved in the integration.

TL;DR: This paper presents a formal model of some aspects of the process of wayfinding, where appropriate elements of human perception and cognition are formally realized using image schemata and affordances using classical propositional logic.

TL;DR: Based on an ontology of imperfection the paper explores a formal model of imperfect geographic information using multi-valued logic and the development of Java software able to assist with a geodemographic retail site assessment application is used to illustrate the utility of a formal approach.

TL;DR: Theoretical Foundations.

TL;DR: A data model, called the entity-relationship model, is proposed that incorporates some of the important semantic information about the real world and can be used as a basis for unification of different views of data: the network model, the relational model, and the entity set model.

TL;DR: In this article, a data model, called the entity-relationship model, is proposed, which can be used as a basis for unification of different views of data: the network model, the relational model, and the entity set model.

TL;DR: In this paper, the authors define a reference architecture for distributed database management systems from system and schema viewpoints and show how various FDBS architectures can be developed, and define a methodology for developing one of the popular architectures of an FDBS.
