Currently, the majority of spatial boundaries are designed in an uncoordinated manner with individual organizations generating individual boundaries to meet individual needs. As a result, current technologies for analysing geospatial information, such as geographical information systems (GISs), are not reaching their full potential. In response to the problem of uncoordinated boundaries, the authors present an algorithm for the hierarchical structuring of administrative boundaries. This algorithm applies hierarchical spatial reasoning (HSR) theory to the automated structuring of polygons. In turn, these structured boundary systems facilitate accurate data integration and analysis whilst meeting the spatial requirements of selected agencies. The algorithm is presented in two parts. The first part outlines previous research undertaken by the authors into the delineation of administrative boundaries in metropolitan regions. The second part outlines the distinctly different constraints required for administrativeboundary design in rural areas. The development of the algorithm has taken place in a GIS environment utilizing Avenue, an objectorientated programming language that operates under ArcView, the desktop software developed and distributed by ESRI.

Stability of the surface generated from distributed points of uncertain location / Yukio Sadahiro in International journal of geographical information science IJGIS, vol 17 n° 2 (march 2003)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 17 n° 2 (march 2003) . - pp 139 - 156 Titre : Stability of the surface generated from distributed points of uncertain location Type de document : Article/Communication Auteurs : Yukio Sadahiro, Auteur Année de publication : 2003 Article en page(s) : pp 139 - 156 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Information géographique [Termes IGN] analyse mathématique [Termes IGN] analyse visuelle [Termes IGN] erreur [Termes IGN] géopositionnement [Termes IGN] imprécision des données [Termes IGN] incertitude géométrique [Termes IGN] stabilité [Termes IGN] système d'information géographique [Termes IGN] visualisation de données Résumé : (Auteur) Conversion of a point distribution into a surface is one of the spatial operations used in GIS. This supports the visual analysis of point patterns, which is usually followed by more sophisticated statistical and mathematical analysis. If the location of points is uncertain, however, the surface obtained becomes unstable and consequently the results of analysis may be unreliable. Though unavoidable in spatial data, locational uncertainty has been rather neglected in the context of spatial analysis. To fill this gap, this paper proposes a method for representing and analysing the stability of the surface generated from an uncertain point distribution. The surface stability is represented by a scalar function called the slope stability function. Its definition, calculation procedure, visualization method, and summary indices are proposed. The method is evaluated through an empirical study, and some findings are shown which help us understand the effect of the smoothing parameter, locational uncertainty, and spatial pattern of points on the stability of a surface.

Extending the automated zoning procedure to reconcile incompatible zoning systems / Olivier Martin in International journal of geographical information science IJGIS, vol 17 n° 2 (march 2003)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 17 n° 2 (march 2003) . - pp 181 - 197 Titre : Extending the automated zoning procedure to reconcile incompatible zoning systems Type de document : Article/Communication Auteurs : Olivier Martin , Auteur Année de publication : 2003 Article en page(s) : pp 181 - 197 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Information géographique [Termes IGN] analyse diachronique [Termes IGN] géographie humaine [Termes IGN] recensement [Termes IGN] Royaume-Uni [Termes IGN] système d'information géographique [Termes IGN] zonage (urbanisme) Résumé : (Auteur) This paper concerns the problem of matching incompatible zonal geographies, for example in the context of comparing census outputs over time. The automated zoning procedure (AZP) proposed by Openshaw (1977) is reviewed and extended to permit its application to the intersection of two zonal systems. A population stress statistic is proposed which may be used in the extended AZP algorithm in order to maximise the match between two zonal geographies. An implementation of this approach is described, and illustrated by reference to UK Census data.
