Exemple d'application de l'analyse typologique (Hierarchicalgrouping) dont la méthode semble appropriée à l'analyse spatiale. Elle permet d'obtenir le découpage d'un territoire quelconque en essayant de maximiser l'homogénéité de chaque partie en
Hierarchical tendencies and regional patterns in the world city network : a global urban analysis of 234 cities
A partir d'une base de données sur les stratégies mondiales d'une centaine d'entreprises commerciales et financières dans 234 villes, une analyse de classification floue permet de définir 22 groupes de villes. Avec leurs membres centraux et hybrides

Nouvelle approche pour ce zonage typologique en utilisant des groupes de moyennes-k de cellules spatiales petites (20'x30') en comparaison de tout le territoire. Chaque cellule est caractérisée par une série de paramètres géomorphologiques
The spatial-temporal structure of relief in space and time can be described in terms based on three initial concepts: spatial organisation, hierarchical succession, and morphological succession. The indivisible space-time of relief is defined
by five dimensional coordinates: time, three coordinates of Euclidean space, coordinate expressing the group of characteristics, that is the level of organisation achieved. Because of the indivisible nature of space-time geomorphology needs to rediscover

The paper discusses the applicability of Butler's model of the life cycle of a tourist area in interpreting various development patterns of Slovene tourist resorts. In order to find out similar development patterns a hierarchical cluster analysis
Interpretation of average heavy metal pollution in flowing waters and sediment by means of hierarchicalgrouping analysis using two different error indices
Analyse de groupes hiérarchiques utilisant deux indices d'erreur appliquée à une étude générale de la pollution par les métaux lourds dans des bassins-versants des montagnes de l'Eifel et de la région loessique voisine. Ces indices permettent une
Cluster analysis was carried out on grain size data (mean, median, sorting, kurtosis and skewness) from the dune covered areas in the Thar desert and from the coastal tract of arid Gujarat. Dendrograms prepared based on hierarchicalgrouping
on the one hand, and the distribution of firms' central offices and level of turnover achieved have also been studied. In relation to the places in which business management has tended to congregate, it proved possible to identify three hierarchicalgroups
Several approaches to economic regionalization are outlined: by economic activity groups, by purpose of the regionalization, or by temporal differentiation. The characteristics of economic regions are objective, spatial, comprehensive
, and hierarchical. Regionalization work should take into account territorial division of labour, balance, centre orientation, accordance with administrative units, and future directions of development. Further work needs to learn from the experience
