Reconstruction of NDVI time-series datasets of MODIS based on Savitzky-Golay filter
This paper uses Savitzky-Golay filter method to reconstruct MODIS 16d NDVI time-series product of Ruoergai plateau wetland from 2000 to 2009
and the results are compared with other two methods— Mean Value Iteration filter and Fourier method.As a result
reconstructing method based on Savitzky-Golay filter has got a better result in both image visual effects and NDVI temporal profiles.High-quality long time-series NDVI which is reconstructed based on this method offers a good foundation for the monitoring of ecosystem of Ruoergai wetland.
