Abstract : |
There is a traditional preference how to store spatial and non-spatial data: attribute data in writing and spatial data in pictures. This led to the use of lists, tables, graphs, almanacs etc. and charts, maps, plans. All designed to reference the respective data type.
The different technologies that have been developed to automate the information extraction from non-spatial and spatial data, can roughly be classified into Data base Systems and Geographic Information Systems. Both systems do essentially the same: extract information through analysis of referenced data. One of the most essential property of both systems is that they operate automatically, therefore potentially without user intervention and very fast.
This paper discusses how the emerging fusion between GIS and DBMS technology can lead to an optimized exploitation of the huge data volumes that are currently being accumulated. Something to be achieved by providing user-friendly 'information dispenser' which prompts an end user to ask the right questions and supplies the answer.
