Can someone please point me to the reference literature for how land use is classified in ecoinvent 3 (and how flows for transitions are defined)?

I am interested in developing CFs from geospatial data at the regional or even gridcell level. I want to be able to do this in a ecoinvent3-compliant way, so I'd need to know how to define e.g. primary/secondary forest, arable land etc., so I can subset my data accordingly. Does there exist e.g. geospatial data that easily allows such classification across the globe (e.g. rasters or shapefiles)?
