[GRASS-dev] New addon r.accumulate calculates weighted flow accumulation using a flow direction map

[Huidae Cho]

Hi All,

I just committed a new addon r.accumulate (
https://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.accumulate).
Unlike r.watershed, this module calculates weighted flow accumulation
directly from the flow direction map and does not require the original
elevation data. I wrote this module many years ago for GRASS 6, but I
almost forgot about it until I read this question:

https://gis.stackexchange.com/questions/280813/compute-flow-accumulation-only-from-flow-direction

Thanks.
