Re-using Flow Accumulation Raster?
This question pertains Generate Watershed tool.
I see there is an option to "Show Flow Accumulation as Grid". Wondering if there is any means of re-using this grid for watershed/stream generation? I was playing around with the parameters in the Watershed Options and had to re-run the tool several times. I noticed it re-calculates the flow accumulation each time. I assume the flow accumulation raster would be the same if the same resolution is specified (let me know if this is not correct), so is there a way to re-use it to save time?
I'm guessing not, but wanted to ask.
