Furthermore the global hydrological data ([HydroSHEDS](https://hydrosheds.org/), [MERIT](http://hydro.iis.u-tokyo.ac.jp/~yamadai/MERIT_Hydro/)) sets are at such high resolution now, that they cannot be dealt with on one processor alone. It is necessary to parallelize the usage of these data and the construction of the routing graph for ORCHIDEE. This parallelization is more driven by the memory needs than the speed of simulation and thus could be different than in ORCHIDEE itself.

The package also includes a viewer which allows to verify the structure of the graph of HTUs which is generated. It provides pictures like the one below.

The Seine basin on an atmospheric grid (in black) is displayed. The HTUs are represented as Voronoi polygons (red) and the elevation of HTUs is colour coded. The main stream of the Seine through the HTU graph is depicted in blue.
