Distributed Parallel D8 Up-Slope Area Calculation in Digital Elevation Models
arXiv: Distributed, Parallel, and Cluster Computing, Volume abs/1605.05773, 2016.
This paper presents a parallel algorithm for calculating the eight-directional (D8) up-slope contributing area in digital elevation models (DEMs). In contrast with previous algorithms, which have potentially unbounded inter-node communications, the algorithm presented here realizes strict bounds on the number of inter-node communications....More
