The present paper discusses the implications and drictions of the roponalparameters used in image recognihon, classification and mapping. lt is indispensablefor improving the accuracy of image classification and mapping quality. It focuseson the discussion of the theory and methodology for the detenninahon of ndonalparameters for spatial information including method for analysis of aukiliary datorelevan to geography and Anowledge-based roponal parameter research method.Applied researches on roponal parameters are also catried out in combination withpattem recoguhon and typological mapping of saline-alkali soils. 展开更多
