In order to study the application potential of HJ-1 satellite imagery in the field of land use research,this paper takes the case of computerized supervision in Qinbei District of Guangxi as an example. Under the premise of assessing the precision of supervised classification template,referring to the second national land survey Rural database,the accuracy of the classification of computer supervision was assessed,and finally according to the computer automatically send classification results to the field for field verification,the results of the classification of a comprehensive and accurate evaluation to prove that the HJ-1 CCD image automatic classification accuracy could meet the requirements of land use survey.
