read_habitatmap_terr(): add option to exclude aquatic patches #35

Closed florisvdh closed 4 years ago

florisvdh commented 4 years ago

Copied from the documentation of the newly added argument keep_aq_patches:

keep_aq_patches Logical; TRUE by default. The data source habitatmap_terr aims at delineating all polygons with at least one (semi-)terrestrial type (i.e. patch). For those polygons, it returns all known habitat types and RIBs as patches. Hence, in several cases polygons do occur with a combination of terrestrial and aquatic patches. Setting keep_aq_patches = FALSE is convenient for use cases where one only wants to look at the (semi-)terrestrial patches: this setting will discard all aquatic patches in 'mixed' aquatic/terrestrial polygons. The aquatic types are defined as those with hydrological class "HC3" (see tag_2) in the types data source.
