| Abstract: | This paper attempted to give an appraisal using TM data from remote sensing technique for detecting rice-field information. The experiment was done in the test area of remote sensing of our university, which posessed the main feature of rice-area in southern China. At first, two methods (the dynamatic cluster and likelihood classifier) were used to draw the information of rice-field. Their area accuracies led to 89. 3% and 98. 49%. To counter the shortages of the two methods and the characteristics of drawing thematic information of rice-field, a new system, step-by-step classifier, was designed. Its result indicated that the area accuracy was 98. 5%. Two reclassifiers were also developed to improve the result of step-by-step classification. They were ratio of two bands and stratified classifier. Their area accuracies were 99. 5% and 99. 4% , respectively. These results seemed to he that this system was effective for detecting rice-field information from TM data. It also provesthat TM is useful for detecting rice-field information. |
