All: I need to generate an ascii text file from a flow direction grid that consists of (among a couple other things that don't really matter at this point) for each pixel:
(1) a unique integer identifier (1 -- N) for the pixel (2) the integer identifier of the downstream pixel (assuming there is ONLY one) (3) the x,y location of the pixel (presumably, the lower left corner of the pixel) has anyone already done something like this? It's needed (along with some header information) as an input file for a gridded distributed hydrologic model, identifying the flow connectivity from pixel to pixel for streamflow routing purposes. I have already formulated conceptually how to do this, but if someone has already done such a thing, why reinvent the wheel?? Any help is appreciated. Regards, Tom
