The study focuses on non stationarity and autocorrelation in spatial data. Supervised MLP machine learning algorithms with spatial constraints have been implemented and tested on a point dataset. MLP spatially weighted classification models and an MLP contiguity constrained classification model are developed to conduct spatially constrained regionalization. The proposed methods have been tested with an attribute‐rich point dataset of geological surveys in Ukraine. The experiments show that consideration of the spatial effects, such as the use of spatial attributes and their respective whitening, improve the output of regionalization. It is also shown that spatial sorting used to preserve spatial contiguity leads to improved regionalization performance.

Titre : The concept and importance of style in cartography Type de document : Article/Communication Auteurs : Giedre Beconyte, Auteur ; Rita Viliuviene, Auteur Année de publication : 2009 Article en page(s) : pp 82 - 91 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] style cartographique
[Vedettes matières IGN] GéovisualisationRésumé : (auteur) The paper outlines the concept of cartographic style that is applicable to practically every type of maps. The structure of the style is rather complex and can be infuenced by geographic space, time and culture. The purpose of cartographic stylistics is to assure that all the elements of visualization consistently support an appropriate perception of map information by the target group. Three largely independent criteria, that can be separately applied to diferent map components on the one hand and combine composition and other aspects into one system on the other, are specifed as decorativeness, expressiveness and originality. Four major groups of styles have been defined by a general degree of the graphic enhancement of visualised data: ‘minimal’, ‘standard’, conventional and conspicuous. Within conventional and conspicuous stylistic groups, more concrete style types such as laconic, constructive, expressive, lightsome, aggressive, soft, antique, luscious, extravagant and artistic are defined.
