STARFM 算法生成湿地类型 TM 反射率数据的应用评价
APPLICATION EVALUATION OF STARFM ALGORITHM IN GENERATING WETLAND-TYPE TM REFLECTANCE DATA
摘要
Abstract
Multispectral remote sensing data with both high temporal and high spatial resolutions can hardly be obtained directly under current data acquisition conditions.We proposed to us STARFM (spatial and temporal adaptive reflectance fusion model)to synthesise the high time series data with high spatial resolution.Nevertheless,the applicability of this model for the geographic areas in China and its prediction precision validation have not yet been substantially done.Accordingly,the Hulun Wetland Nature Reserve in Inner Mongolia is selected as the study area,and with the help of Landsat-5 TM data and high time series MODIS reflectance products,we used STARFM algorithm to generate the TMdata with high time series feature,and then made the comparative validation analysis on it with the actual TM reflectance data.Result showed that the STARFM algorithm has a higher prediction capability on the phase features of different terrain categories in wetland area varying along with time phases under the condition of preserving certain prediction accuracy in space,it is particularly suitable for the spatiotemporal fitting or data prediction research in those wetland areas where the reflection characteristics change little along with the time phases.关键词
