Geographic data preprocessing is the most effort and time consuming step in spatial data mining. In order to facilitate geographic data preprocessing and increase the practice of spatial data mining, this paper presents Weka-GDPM, an interoperable module that supports automatic geographic data preprocessing for spatial data mining. GDPM is implemented into Weka, which is a free and open source classical data mining toolkit that has been widely used in academic institutions. GDPM follows the Open GIS specifications to support interoperability with Geographic Information Systems. It automatically generates data at two granularity levels without using prior knowledge and provides support for both distance and topological spatial relationships.
