Data model for Layer 1 of CARTNAT showing sub-models and component layers. Layer one “biophysical integrity” was built using expert weighting of key spatial layers available at the national scale for France. Where possible spatial layers were improved using sub-models that take advantage of historical data and regional variation based on ecoregions (GRECO native forest model and high probability forest model). Final input layers are shown as well as the priority order in which they were combined to produce the final layer.
[5/5] #CARTNAT soutient aussi l’analyse de la connectivité écologique, essentielle pour limiter la fragmentation et maintenir les processus naturels. Il est utilisé par Patrinat (MNHN, OFB, CNRS) pour relier les zones naturelles dans une stratégie à grande échelle. #geography #mapping #naturalness
