摘要:This paper discusses an approach for extracting supporting evidence from multisource spatial data and by rule-based modelsto incorporate the evidence with pre-classified Landsat TM data for improving classification accuracy. The process wasfocused on the extracted "possibly misclassified pixels" (PMPs) only. Based on Dempster-Shafer's theory of evidence, theconcepts of homogeneous, heterogeneous. and conflicting evidence and the rules for evidential combination are discussed.Boolean logic, conditional statement, and spatial relationship operations were employed in the models. By running the models,correct labels for the PMPs were judged by pooled evidence from multitemporal Landsat TM data and multisource spatial data
