I have a stream network and DEM file both in raster format. I need to extract values from DEM to stream network. For the analysis in stream network after that, I need to find out the places for hydro power based on various criteria of head, stream order. So how can i start my work?
I am planning to convert both raster file into text file using numpy array and extracting head for all the cells of stream and after that i will start processing. Is that a good idea to start or is there any other way?
I am quite new to python.
