Vegetation is one of the most important and most sensitive impacting factors of soil erosion.Vegetation information products that have high resolution in both time and space are needed to study dynamic changes of vegetation,for better understanding and monitoring of soil and water loss.A method is proposed to get high spatial and temporal resolution NDVI products,by matching the histogram of ETM NDVI(30 m) to that of SPOT/VEGETATION NDVI product (1 km,one scene every month).The estimated NDVI products(30 m,...
