This paper assesses the utility of statistical models by examining methodological issues associated with empirical analysis of hydraulic and channel geometry relationships. It also describes and presents examples of advanced statistical models
that promise to enhance our understanding of the structure and dynamics of fluvial systems.
Chinese statistics : classification systems and data sources
Agriculture ; China ; Classification ; Data ; Data base ; Economy ; Industrial sector ; Industry ; Service ; Statistics
China researchers make frequent use of official Chinese statistics, but these statistics are often not well understood. A second part of the article provides an overview of the wealth of Chinese statistics now available. It points out
the limitations of some of these sources and provides references to a secondary literature that discusses the meaning and quality of particular Chinese statistics.

This paper introduces an internet GIS for historical regional statistics developed by the Laboratory of Spatial Information Science, Doctoral Program in Geoenvironmental Sciences, University of Tsukuba. The paper discusses the objectives
of this project, the available data, its scope and features, and some of the prospects and challenges as an online geospatial database facility of historical statistics of Japan since the Meiji period.

Using the GIS techniques, and supported by Auto CAD software, the A. develops a practical method to make statistical maps and a software (SMT) to make small-scale statistical maps using C language.
Débat sur les interfaces entre systèmes d'information géographique et analyse spatiale : les AA. mettent l'accent sur certains paradigmes relatifs à l'analyse de données spatiales, et qui découlent de ces interfaces. Proposition d'améliorations

Structure organisationnelle d'un service de statistiques| par quelles voies s'élaborent les statistiques, les concepts utilisés. Elaboration d'un système de traitement des données| le traitement des données proprement dit| l'analyse et
The paper considers the potential of geographic information systems as a tool for the analysis of the socio-economic environment. It is necessary to find a structure which allows analysis at a wide range of scales. Raster models may be constructed
that overcome many of these difficulties, and can be used as a basis for spatial statistics and modeling of socioeconomic phenomena.

Discussion autour de quelques problèmes statistiques soulevés par la loi rang-taille, notamment lorsque l'on considère que le rang n'est rien d'autre qu'une simple transformation ordinale de la taille. Application au système urbain de la Belgique.
Application de la statistique circulaire pour l’étude des trajets domicile-travail dans la région sud-orientale de l’Etat australien du Queensland. Les AA. développent les outils des systèmes d’information géographique. Deux mesures descriptives
The aim of the present paper is to review some of the basic principles of system dynamics and of landscape evolution, and then to compare he former with the latter. It will be seen that not all geomorphic features can be treated by system theory

The article deals with the national atlas, the atlas information system and the multimedia in Austria. The ÖKOR-atlas online is a cooperative scientific cartographic project with the goal of developing an online system that enable the user
to explore national (Austrian) as well as international (European) statistical information. - (IfL)
This study demonstrates that the utility of simultaneous-equation analysis is limited for fluvial systems by inherent multicollinearity among hydrologic and morphologic variables.
