FricMaps
FricMaps: A Tool for Modeling Landscape Connectivity and Fence Permeability.
Resistance surfaces underpin ecological connectivity modelling, yet their construction is often hard to reproduce because it depends on heterogeneous input data and poorly documented preprocessing choices. FricMaps automates the generation of standardised land-cover and resistance surfaces through modular vector preprocessing and a rule-based rasterisation engine driven by a user-editable classification table. It explicitly integrates underrepresented anthropogenic barriers such as fences, applies attribute-dependent buffering of roads and railways, and uses wildlife crossing structures to locally restore permeability at validated locations. Contextual weighting by slope and by distance to any class or custom source supports scenario generation. Outputs are directly compatible with graph-based connectivity software such as Graphab. Source code is GPL-3.0-or-later; documentation and the default classification table are CC BY 4.0 (see LICENSE).
