An information system is generated and Domlem algorithm is applied for extraction a minimal set of rules.The algorithm builds two text files (outputTxt=name): the first with isf extension for more deep analysis with non geographic software like 4emka and JAMM ; the second file with rls extension hold all the set of rules generate. An output map (outputMap=string)is generated for region classification with the rules finded and the criteria stored in GRASS geodb.
The module can work very slowly with high number of criteria and sample. For bug please contact Gianluca Massei (firstname.lastname@example.org)
