Hedgerows in Rennes MétropoleHaies bocagères sur Rennes Métropole
Haies bocagères sur Rennes MétropoleHedgerows in Rennes Métropole
This dataset provides GIS data on hedgerows (bocage) across the Rennes Métropole area, produced during a spring 2017 study by Audiar, the local urban planning agency. The work involved various geoprocessing tasks based on data supplied by several watershed management syndicates and the Breizh Bocage association. The resulting layer maps hedgerow features across the metropolitan territory and is published by Rennes Métropole as open data, useful for landscape planning and environmental analysis in the region.L’Audiar a mené, durant le printemps 2017, un travail SIG sur le bocage, à l’échelle de Rennes Métropole, incluant différents géotraitements. L'agence a utilisé pour cela les données fournies par les différents syndicats de bassins versants et par l'association Breizh bocage. Cette couche a pour...
