We used GRASS GIS, a software package with efficient terrain analysis algorithms, to perform each of these transformations. While this package is intended for SMP systems, there is demonstrated interest in merging the high-level functionality of GRASS with the efficiency gains of HPC systems. Unfortunately, this largely consists of sporadic academic manuscripts and disjointed Wiki-based instruction manuals at the moment, with no systematic, supported method accompanying the software. Thus, We encountered two options for speeding up this process. First, we could have written our own parallelized algorithm
