I need DEM, Flow Direction and Flow Accumulation data with 3km or will take more storage to calculate DEMs, convert to raster base and conduct the flow routing. Can anyone tell me of a free portal to download river discharge data? I want to extract NDVI values on each pixel (like ASCII files in GIS) for every time
