Generate a flow direction map #14

dem格网 图片2 Dear Mr. Joel Oskarsson, in the 'Graph Construction' section of your paper, you aggregate neighbor nodes in eight directions. A student would like to ask for your advice on how to selectively aggregate neighbor nodes. Could you also explain how to generate a flow direction map, for example, as shown below: Based on neighbors in the D8 or D4 directions, generate a flow direction map from the DEM image, and then aggregate the neighbor features of upstream river nodes. Article source: https://eartharxiv.org/repository/view/3018/, but this article does not share its code, which is very challenging for beginners.

I am closing this issue because it has become stale.
