Modified Water Information Extraction Method Based on Remote Sensing Images
Abstract: By analyzing the error extracted areas which is caused by using NDWI and NDVI methods indi-vidually, a modified water information extraction method was proposed and tested. The method interconnects the NDWI, NDVI and mathematical morphology methods together. The HJ-1A sequence statelier images in the Poyang Lake during 2010 to 2011 were selected as case study. The water information were recognized and extracted by the modified method and compared with three conventional methods based on confusion matrix. The results show that modified method is more accurate than three conventional methods by improv-ing 9.43% on average.
