Optimize D8FlowDir algorithm #240

Open jcphill opened 1 year ago

jcphill commented 1 year ago

Modify D8FlowDir algorithms to implicitly increment points in the interiors of flats that are all at the same level, and to only explicitly update points at the edges. Produces identical output but is much faster for large inputs with large flat areas.

Thanks for this. I hope to check it out when I get time.
