Evaluation on wetland classification in Yancheng natural reserve, China using HJ-1 data

Remote sensing of wetlands is one of important aspect in application and research of remote sensing. This paper studied the HJ-1 CCD data (30m/pixel) applied to wetland resource analysis of the Yancheng national natural reserve. And we gave evaluation on ability of the HJ-1 CCD data in wetland classification. Firstly, we gave the spectral analysis of the typical wetland types. The extraction experiments were carried out by supervised and unsupervised classification methods. Finally, we compared the classification results with those gained from Landsat-5 TM data (June 2007). It indicates that the HJ-1 CCD data have good recognition performance.
