Grid Wetlands Strategy of the Rhône Plan

layer derived from the grid_poly layer, layer containing all the data on the indicators, by the layer ZH_planrhone_polygoneL93_fusion which delimits zoning of the wetlands concerned by the Rhône-Saône plan. Details of the layers used (extract from CONTRIBUTION TO THE ELABORATION OF THE HUMIDES STRATEGY OF THE RHONE PLAN) Grid_poly: this layer is composed of a set of square meshes of 500 m*500m for which each indicator has been calculated. Date: Dec 2015. Data producers: Acer campestre ZH_planrhone_polygonL93_fusion: this layer delimits the wet envelope known to date and concerned by the Plan Rhône Saône. It is based on a fusion of the adjacent polygons of the ZH_planrhone_polygonL93 layer. It was used as the basis for the calculation of certain indicators. Date: may 2015. Data producers: Acer campestre ZH_planrhone_polygonL93: this layer brings together all inventories of existing HZs. All the source data have been merged into a single layer with a complete winning table that identifies, among other things, the origin of the polygon delimitation (departmental inventories, EPTB Saône Doubs inventory, or studies of orphan ZH) and the code that was assigned by the producer organisation of the data, possibly making it possible to link with the database that gathers all known data on the ZH (Medwet database type) where it exists.
