Application d'analyse et interprétation des caractéristiques morphologiques des réseaux hydrographiques.

Checks the hydro-network from the outfall & flip the arcs if necessary. A R script using the sf package.

[Not thoroughly tested] Hydrographic standards for uncertainty tolerance, bathymetric coverage, feature detection and feature search are often derived from IHO S-44, once an order has been established as a criteria. This script automates the calculation of specs based on said criteria, according to user defined min / max site water depth.

A QGIS plugin. Checks the hydro-network from the outfall & flip the arcs if necessary.
