Friction
To each land use class and subnetwork is associated a numeric value (no value means that matching class is ignored).
This numeric value represents either a friction coefficient or a favorability class.
Coefficient
The classic method is to assign a friction coefficient modelizing the effective resistance of matching habitat to matching subnetwork species dispersal.Classes de favorabilité
Favorabilty classes allows user to classify land use according to its quality without giving a quantified numeric value. Specified value then represents land use favorability class (for instance from 1 for unfavourable to 5 for very favourable).Fichier CSV
Coefficients can be imported from and exported to a CSV file.
