Abstract
While recent hardware and software developments made Geographic Information Systems (GIS) systems widely available there are still many problems to be solved. Partially in contrast to the mainstream in GIS research, the most important technical issues of real-world projects point to processes which support an efficient, economic but long living ‘data life cycle’, namely: 1. Data capturing; 2. Continuous map revision, database update and quality checking; 3. Map generalization; 4. Spatial data integration and transfer.
All four processes are discussed and ways are shown to overcome those practical problems which contribute to the majority of the resources in realworld GIS projects. Most of the techniques mentioned have not been investigated very far or are still in an early stage though there are some pragmatic starting points available. Therefore the author proposes under the terms of ‘Sustained Spatial Data Management’ (S2DM) a pragmatic research focus and provides some examples and ideas to investigate further.
