Unveiling spatial uncertainty: a method to evaluate the fuzzy nature of functional regions

Abstract

ABSTRACT The evaluation of the level of spatial uncertainty builds theoretically on fuzzy set theory and the premise that the affinity of a basic spatial unit may assume values along a continuum between zero and full affinity. The paper briefly presents the motivation for the evaluation of fuzziness in functional regions based on daily travel-to-work flows. It discusses the existing measures of affinity and proposes a new approach to evaluate the fuzzy nature of functional regions. The proposed methodological innovations are tested using the example of the two-tier hierarchical system of functional regions in the Czech Republic.
