Visualization Support for Multi-criteria Decision Making in Geographic Information Retrieval [chapter]

Chandan Kumar, Wilko Heuten, Susanne Boll
2013 Lecture Notes in Computer Science  
There is a need for more sophisticated visual interfaces to enable end-users in discovering knowledge hidden in multidimensional geospatial databases.  ...  In the current means of GIR interfaces, users could easily visualize the geo-entities of interest on a map interface via sequential querying or browsing of individual categories.  ...  In this paper we argue the need of interactive visual interfaces for a geographic information retrieval system, so the end-user can easily explore and interact with the spatial database.  ...
