habitatmap_terr: the interpreted, terrestrial part of habitatmap_stdized

The data source habitatmap_terr is the further interpreted, terrestrial part of 'habitatmap_stdized' (which, in turn, was derived from the raw data source 'habitatmap'). It is a GeoPackage that contains: habitatmap_terr_polygons: a spatial polygon layer in the Belgian Lambert 72 coordinate reference system (EPSG-code 31370); habitatmap_terr_types: a table with the types that occur in each polygon. This version of habitatmap_terr was derived from version 'habitatmap_stdized_2020_v1' as follows: it excludes all polygons that are most probably aquatic habitat or RIB. These are the polygons for which all habitat or RIB types are aquatic. In the process, a distinction was also made between 2190_a and 2190_overig. There is no exclusion of aquatic types when these coexist with terrestrial types in the same polygon; it excludes types which most probably are no habitat or RIB at all. Those are the types where code_orig contains "bos" or is equal to "6510,gh" or "9120,gh"; it translates several main type codes into a corresponding subtype which they almost always represent: 6410 -> 6410_mo, 6430 -> 6430_hf, 6510 -> 6510_hu, 7140 -> 7140_meso, 9130 -> 9130_end; it distinguishes types rbbhfl and rbbhf. See R-code in the GitHub repository 'n2khab-preprocessing' at commit dfdd73d for its creation from the habitatmap_stdized data source. A reading function to return the data source in a standardized way into the R environment is provided by the R-package n2khab. Attributes of habitatmap_terr_polygons: polygon_id description_orig: polygon description based on the original type codes in the habitatmap data source description: based on description_orig but with the interpreted type codes source: states where description comes from: either habitatmap_stdized or habitatmap_stdized + interpretation Attributes of habitatmap_terr_types: polygon_id type: the interpreted habitat or RIB type. certain: TRUE when the type is certain and FALSE when the type is uncertain. code_orig: original type code in raw habitatmap. phab: proportion of polygon covered by type, as a percentage. source: states where type comes from: either habitatmap_stdized or habitatmap_stdized + interpretation
