read_ecoregions: Return the 'ecoregions' data source as an 'sf' object

In inbo/n2khab: Providing Preprocessed Reference Data for Flemish Natura 2000 Habitat Analyses

Return the ecoregions data source as an sf object

Description

Returns the raw data source ecoregions, with unique polygon identifiers polygon_code and polygon_id. Multiple polygons can have the same region_name. The coordinate reference system is 'BD72 / Belgian Lambert 72' (EPSG-code 31370).

Usage

read_ecoregions(file = file.path(locate_n2khab_data(), "10_raw/ecoregions"))

Arguments

file

The absolute or relative file path of the data source. The default follows the data management advice in the vignette on data storage (run vignette("v020_datastorage")). It uses the first n2khab_data folder that is found when sequentially climbing up 0 to 10 levels in the file system hierarchy, starting from the working directory.

Details

Original columns of the raw data source were mapped as:

• CODE -> polygon_code

• NR -> polygon_id

• REGIO -> region_name

• DISTRICT -> district_name

Apart from the label, there is no complementary information between polygon_code and polygon_id.

Value

A Simple feature collection of geometry type MULTIPOLYGON.
