Building GIS on Top of the Open DBMS 'Postgres' (Het Bouwen van een GIS op Basis van het Open DBMS 'Postgres')

Abstract

Many commercial Geographic Information Systems have a dual architecture: the thematic information is stored in a relational database management system and the spatial information is stored in a separate subsystem capable of dealing with spatial data and spatial queries. Besides not being elegant conceptually, this dual architecture also reduces the performance, because objects have to be retrieved and compiled from components that may be stored far apart in the two subsystems. We present a solution based on the extendable database management system 'Postgres,' in which thematic and spatial data are stored together.
