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

<p>This map is a combination of the <a href="https://zenodo.org/records/13865531">standardized habitat map of Flanders</a> (version habitatmap_stdized_2023_v1)&nbsp;and <a href="https://zenodo.org/records/14203168">the watersurface map of Flanders</a> (version watersurfaces_2024). It contains standing water Natura 2000 habitat types (2190_a and 31xx) and regionally important biotopes (rbbah) in Flanders.</p> <p>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.</p> <p>For each of the other aquatic habitat types (31xx and rbbah) we select the watersurface polygons that overlap with the selected&nbsp;habitat type polygons of the standardized&nbsp;habitat map. We also select&nbsp;polygons of the standardized habitat map containing standing water types but that do not overlap with polygons of the watersurface map.</p> <p>The&nbsp;<code>watersurfaces_hab.gpkg</code> file is a GeoPackage that contains:</p> <ul> <li><code>watersurfaces_hab_polygons</code>: a spatial layer with the selected polygons that contain standing water habitat types or regionally important biotopes.&nbsp;</li> <li><code>watersurfaces_hab_types</code>: a table with information on standing water habitat types and regionally important biotopes in each watersurface polygon.</li> </ul> <p>The R-code for creating the <code>watersurfaces_hab</code> data source can be found in the GitHub repository&nbsp;<a href="https://github.com/inbo/n2khab-preprocessing/tree/58138a8/src/generate_watersurfaces_hab">'n2khab-preprocessing'&nbsp;at commit&nbsp;58138a8</a>.</p> <p>A reading function to return the data source in a standardized way into the R environment&nbsp;is provided by the R-package&nbsp;<a href="https://github.com/inbo/n2khab">n2khab</a>.</p>
