Deriving a global river network map and its sub-grid topographic characteristics from a fine-resolution flow direction map
This paper proposes an improved method for converting a fine-resolution flow direction map into a coarse-resolution river network map for use in global river routing models. The proposed method attempts to preserve the river network structure of an original fine-resolution map in the upscaling proce...
