Geographic Data Mining and Knowledge Discovery An Overview [chapter]

Jiawei Han, Harvey Miller
2009 Geographic Data Mining and Knowledge Discovery, Second Edition  
digital geographic data easily overwhelm mainstream spatial analysis techniques that are oriented towards teasing scarce information from small and homogenous datasets.  ...  There is often much more information in these databases than the "shallow" information being extracted by traditional analytical and query techniques.  ...  Developing and supporting geographic data warehouses. A glaring omission from current research in GKD techniques is the development and supporting infrastructure for geographic data warehouses (GDW).  ...

HANDLING IMPRECISION IN QUALITATIVE DATA WAREHOUSE: URBAN BUILDING SITES ANNOYANCE ANALYSIS USE CASE

F. Amanzougarene, M. Chachoua, K. Zeitouni
2013 The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences  
In previous work, we have proposed an original approach of qualitative data warehouse modeling, which permits integrating qualitative measures.  ...  In classical data warehouses, facts are composed of numerical measures and dimensions which characterize it. Dimensions are organized into hierarchical levels of detail.  ...  OLAP refers to the technology that allows users to efficiently retrieve the information stored in a data warehouse. To conceptualize data in a data warehouse, the multidimensional model is used.  ...
