Er-model of classification system of multidimensional dana in vector gis

Abstract

Peculiarity of geographical data classification is also shown in the possibility of cartographical presentation of a process and results of the analysis. The given work contains one of the approaches to formalization of the automatic classification process of the multidimensional spatial data in GIS environment with the help ofER- modelThe described model is used in software GisCluster. GisCluster developed by authors may function together with MS IIS web-server for distributing functions of spatial data classification, and also visualization of a process and results of the analysis through the Internet.
