AN id=EnChDivSummary name="EnDivSummary">The Zhalong National Nature Reserve (NNR) that located in Heilongjiang Province was selected as a study area,five temporal ETM+imagery covering the study area were used as material for wetland mapping.An evidential reasoning (ER) approach that built on Dempster-Shafer theory was introduced to combine the five images.The authors used a new algorithm named minimum distance to generate evidence support from ETM+image.The results indicated that ER was an effective approach to integrate multi-temporal imagery for wetland mapping.Compared to classification results of single image based maximum likelihood classifier (MLC),the improvement of overall accuracy by ER approach was apparent (2%~ 12%).
