EUNIS classifications

There are four EUNIS classifications included in the one single data set eunis_habitats, namely:

1. EUNIS classification from 2007, revised in 2012.
2. EUNIS marine classification from 2019
3. EUNIS marine classification from 2022
4. EUNIS terrestrial classification from 2021

For example, to access the marine habitats classified according to EUNIS revision of 2022:
