his paper investigated the regionalization problem of remote sensedimage and generated the regionalization map using remote sensed image and otherthematic maps such as soil type and landuse etc.The paper also introduced the multi-dimension bright value overlap index to select the best bands compose

and fulfilledthe remote sensed image classification on the base of geographic information system.Finally

a rapid resample program and a fast Bayes classifier were provided

bothmethods used the computer base memory as large as possible

so they were much fastthan usual methods.All methods above were examined in the rice information extra-ction in Wuxi county

Jiangsu Province.
