Return the data source habitatmap as an sf multipolygon layer

Source: R/read_habitatdata.R

Returns the raw data source habitatmap (De Saeger et al., 2020) as a standardized sf multipolygon layer (tidyverse-styled, internationalized) in the Belgian Lambert 72 CRS (EPSG-code 31370). Given the size of the data source, this function takes a bit longer than usual to run.

read_habitatmap(
  file = file.path(locate_n2khab_data(), "10_raw/habitatmap"),
  filter_hab = FALSE,
  version = c("habitatmap_2020", "habitatmap_2018")
)

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.
filter_hab

If TRUE only polygons that (partially) contain habitat or a regionally important biotope (RIB) are returned. The default value is FALSE. This requires the corresponding version of the processed data source habitatmap_stdized to be present in its default location inside the n2khab_data folder.
version

Version ID of the data source. Defaults to the latest available version defined by the package.

Value

A Simple feature collection of type MULTIPOLYGON.

Examples

if (FALSE) {
# This example supposes that your working directory or a directory up to 10
# levels above has the 'n2khab_data' folder AND that the latest version of
# the 'habitatmap'
# data source is present in the default subdirectory.
# In all other cases, this example won't work but at least you can
# consider what to do.
