Abstract:

With the 250m MODIS/NDVI times series datasets as main data source we reconstructed NDVI times series datasets with higher quality by Sacizkky-Golay filter, and we merged 500m MODIS multi-spectral reflectance data with 90m DEM data. With a combination of unsupervised classification and decision-tree methods, we extracted the land cover classification of Amur-Heilong River basin. We assessed the classification accuracy by using the current land cover map and high-resolution remote sensing images. The results indicate that acquirement of more accurate land cover classification by using MODIS/NDVI times series datasets is fessible.

Key words: Amur-Heilong River basin, land cover, MODIS, NDVI time series
