Some linear information on satellite images is the reflections of the linear structures of the earth surface,and some of these lineaments are closely related to the mineral distribution.The enhancement processing of TM remote sensing image data of Tuwu-Yandong belt in East Tianshan Mountain using ERDAS IMAGE8.7 image processing software was carried out.The information of linear structures of Tuwu-Yandong belt was extracted using Hough transformation and based on methods and thinking established by other researchers and Matlab7.0 platform.Meanwhile,the extracted results were compared with ones obtained by manual extraction,the way to extract the information of linear structures in this area was discussed.This work provided references for the further prospecting and the disposition of investigation in the study area.
