EUNIS four classifications
The eunis_habitats
data set comprises four habitat
classifications:
- EUNIS classification from 2007, revised in 2012.
- EUNIS marine classification from 2019.
- EUNIS marine classification from 2022.
- EUNIS terrestrial classification from 2021.
The column classification
distinguishes which is
which:
dplyr::distinct(eunis_habitats, classification)
#> # A tibble: 4 × 1
#> classification
#> <chr>
#> 1 EUNIS_2012
#> 2 EUNIS_M_2019
#> 3 EUNIS_M_2022
#> 4 EUNIS_T_2021
For example, to access the level 1 marine habitats classified
according to EUNIS revision of 2022 ("EUNIS_M_2022"
):
dplyr::filter(eunis_habitats, classification == "EUNIS_M_2022", level == 1L)
