ZHP occupied by developments or uses that may alter their functions in Brittany — Synthesis
Description
Potential wetlands (ZHP, Agro-Transfert Bretagne, 2008) of Brittany occupied by developments or uses that may alter their functions are the result of a cross between potential wetlands and the cumulation of the following 5 developments or uses:
— urbanisation (artificialised areas of Brittany in 2010 of ADEUPa)
— transport infrastructure (BD TOPO 2017)
— water bodies and artificial basins > 500 m² (BD TOPO 2019)
— cultivated areas (GPR 2018)
— forest plantations (BD Forest V2 2012)
This layer that cumulates uses arises from the union of the crosses between the previously mentioned layers and the ZHPs. The method used frees oneself from overlays that may exist between the margins of the data and thus does not overestimate the total potentially altered surfaces.
These data have been produced as part of the report “Wetlands of Brittany — State of the alterations, Restoration issues”, available at the following link:
https://rerzh.forum-zones-humides.org/ressources-et-outils/rapports/zones-humides-de-bretagne-etat-de-lieux-des-alterations-enjeux-de-la-restauration/
A detailed description of the method used is available on pages 94 to 104.
