Map of standing water habitat types and regionally important biotopes in Flanders

This map is a combination of the standardized habitat map of Flanders and the watersurface map of Flanders. It contains standing water Natura 2000 habitat types (2190_a and 31xx) and regionally important biotopes (rbbah) in Flanders.


The polygons with 2190_a habitat (dune slack ponds) are generated by selecting all watersurface polygons that overlap with dune habitat polygons (21xx) of the standardized habitat map.


For each of the other aquatic habitat types (31xx and rbbah) we select the watersurface polygons that overlap with the selected habitat type polygons of the standardized habitat map. We also select polygons of the standardized habitat map containing standing water types but that do not overlap with polygons of the watersurface map.


The watersurfaces_hab.gpkg file is a GeoPackage that contains:




watersurfaces_hab_polygons: a spatial layer with the selected polygons that contain standing water habitat types or regionally important biotopes. 

watersurfaces_hab_types: a table with information on standing water habitat types and regionally important biotopes in each watersurface polygon.



The R-code for creating the watersurfaces_hab data source can be found in the GitHub repository 'n2khab-preprocessing' at commit f12a51e.


A reading function to return the data source in a standardized way into the R environment is provided by the R-package n2khab.
