Reliability Evaluation and Migration of Wetland Samples

As one of the most important steps in classification and mapping research, sample acquisition updating cost a lot time energy researchers. The high temporal spatial dynamic characteristics wetland make reliable selection more challenging. It is especially for series to address problem how apply sets images with different periods. This article evaluated reliability historical samples by using optical synthetic aperture radar remote sensing data from perspective water inundation frequency, three migration methods based on rule set, reclassification, spectral similarity were proposed carry out experiment Tibetan Plateau. In addition, relationship between number accuracy analyzed. reuse can quickly obtain accurate sets, which lays foundation study series.
