# FY3A MERSI数据的植被指数产品“异常条带”问题处理方法探究Research on Method of “Abnormal Stripe Problem” of Vegetation Index Product of FY3A MERSI

Abstract: There are so many problems in the NVI product that affect the availability of the NVI product. The main problem includes abnormal stripe, which is summarized in the NVI product. Apply manual method and auto method, which could solve the significant problems of the NVI and improve its quality, has been discussed. Auto method avoids wasting a lot of time to search the area of abnormal stripes. Thus the abnormal stripes are removed rapidly by using mathematical morphology to do boundary detection. Finally, the quality of FY3A MERSI has been improved and the data availability has been ensured.
