The Estimation Method for Winter Wheat Planting Area Based on MODIS Multi-temporal Data
摘要
Abstract
Taking Henan Province as research area,adopting MODIS-NDVI 16 d synthetic data sets during winter wheat regreening and elongation stage,winter wheat area was estimated by using remote sensing method.Using data excluding non-cultivated land,Minimum Noise Fraction Transform method was adopted to conduct data compression processing,and the Linear Pixel Unmixing method based on sequential maximum angle process cone model was used to conduct estimation and calculation.Compared with the actual statistic data,under the special climate impact,the relative error was 0-7％,indicating the method could be used to estimate crops' planting area.关键词
