Friction

To each land use class and subnetwork is associated a numeric value (no value means that matching class is ignored).
This value represents the effective resistance of matching habitat to matching subnetwork species dispersal.
Coefficients can be imported from and exported to a CSV file. Please ensure such CSV file uses semi-comma ';' as seperator and encoding UTF-8.
Absolute value of coeffcients is not essential. What does matter is the proportionality ratio between favorability classes.
Habitat coefficient shall be set to 1.
