Multicriteria methods and logic aggregation in suitability maps

In this paper, we identify and describe fundamental logic properties of multicriteria methods for land-use suitability analysis and the design of suitability maps. The existing multicriteria methods can be evaluated from the standpoint of their …

Consistently handling geographical user data: merging of coreferent POIs

In the context of geographic information systems (GIS), points of interest (POIs) are descriptions that denote geographical locations which might be of interest for some user purposes. Examples are nice views, historical buildings, good restaurants, …

LSP suitability maps

In this paper, we propose the concept of logically aggregated geographic suitability maps (LSP-maps). The goal of LSP-maps is to provide specialized maps of the suitability degree of a selected geographic region for a specific purpose. There is a …

Comparison of multicriteria methods for land-use suitability assessment

In this paper we investigate properties of multicriteria methods that are used for building land-use suitability assessment criteria. We identify and describe fundamental properties that are of interest in the land-use suitability analysis and the …

A twofold fuzzy region model for imprecise (duality control of geographic information

In this paper we propose a new data model for imperfect geographic information: a twofold fuzzy region model; which is an extension of both the fuzzy region model and the egg/yolk model. We show how it is meaningful and practically useful in …

Suitability maps based on the LSP method

In this paper we propose the concept of logically aggregated geographic suitability maps (S-maps). The goal of S-maps is to provide specialized maps of the suitability degree of a selected geographic region for a specific purpose. There is a wide …

Fuzziness in spatial databases and GIS

This paper explains why and how spatial databases and geographic information systems can benen̆matchedfb01t from an appropriate representation of imprecise and/or uncertain information. Not only are the imprecission and uncertainty inherent to the …
