In this paper, the visualization of extracted information from spatial data base into geographical representation is demonstrated. The visualization techniques are essential for easy understanding of the information content of the data sets collected during the field survey for a particular study. The data mining techniques are used for extracting the information content of the data sets. The objective of the present study is to employ the information visualization techniques and data mining techniques for the spatial data base pertaining to a particular geographical region. The spatial database is built for the Latur district in Maharashtra state of India. The use of the database in the form of knowledge discovery is demonstrated visually in the geographical representation. The objectives are as given below: • Extraction of information using data mining techniques like collection, classification, tabulation, clustering, and association rule mining are used on different classes of spatial and non spatial attributes. • Designing and plotting of data to prepare maps like road map, taluka maps, water bodies, railway, contours, village locations, etc. with their different attributes. • Making user friendly access to Latur district information like searching for a village location or measuring distance between two or more locations etc. • Visualizing class clusters through geographical representation. • Village wise visualization of population, sex ratio and literacy.
