7. 80% of all GIS commands are connected with data capturing, transformation, and cleaning operations. Albrecht 1996

8. Taxonomy of GIS Operations

9. that users can interactively direct database operations and mediate database navigation to uncover interesting patterns GIS as a process

10. Knowledge Discovery in Databases Data Mining How can we explore millions of records, hundreds of fields, and find patterns?

11. KDD Methods Classification Clustering Clustering Summarisation Summarisation Predictive Modelling Predictive Modelling Change and Deviation Detection Change and Deviation Detection

12. Enable data exploration, analysis, and visualisation to be conducted at a much higher level of interaction between GI users and databases. Put effective “knowledge construction” tools in the hands of GI users GIS + Gvis + KDD

13. GVis Exploration driven by visual thinking GIS Exploration driven by operations KDD Exploration driven by automated information processing

14. Integration of GVis, GIS, and KDD will uphold the design of the next generation of systems
