Geo-information nowadays encompasses data of different types and origins recorded at different time periods using a variety of methods. To exploit the full potential of this data and to use it in a synergistic fashion in image analysis for example, new techniques for data management and handling have to be developed. This paper is based on a process oriented data model, using a relational database management system. The database includes the varying data types, such as spatial data, attribute data and meta-data. The purpose of this study was to develop an operational interface for non-GIS, non-database specialists to facilitate them the usage of the data. The interface automatically creates small dialogs that offer the user the results of a database query. Based on the user's selection in the dialog new queries are composed and sent to the database. This dynamic data retrieval, in combination with the process oriented database, allows the user to find all related data of a selected spatial object and present it, if desired, to the user. The automated creation of complex query statements enables the 'once in a while' GIS user to work with a complex database without any knowledge of the database structure.
