Several downloads (20231005, 20231021, 20231023, 20240415, 20240412) and contacts with the authors (David Keith david.keith@unsw.edu.au, Jose Ferrer Paris j.ferrer@unsw.edu.au) were required.
Within the various releases:
- All the objects have been renamed
- M1.10.WM.nwx_v1.0.json has been added
- MT2.2.IM.orig_v1.0.json has been added
- T1.3.WM.nwx_v1.0.json has been updated (old name was: T1_3_Trop_montane_rainforests.json)
- T7.1.web.alt_v2.0.json has been updated (old name was: T7_1_Croplands.json), but the new version was truncated; consequently:
- T7.1.web.alt_v2.0.json.bz2 has been obtained by the author
- S1_2_Endolithic_systems.json exists only in one of the old release.
Vectors (geojson format...) have been imported in PostGIS with the script import.sh.
PostGIS geometries have been pre-processed with the script iucn_get.sql.
The original categories have been organized into 220 codes representing:
- 10 realms (4 main, 6 transitional)
- 25 biomes
- 110 functional groups (major or minor occurrence) of which 171 are currently present class_code_objects.csv.
Flat version has been obtained (10 hours processing with 140 threads dedicated) with the DOPA flattening sequence, with configuration as by workflow_parameters.conf. The result is a PostGIS table exported as raster, where the atomic object/pixel (cid) is a unique combination (1897634 cid in total) of ecosystem functional groups (EFG) overlapping each other. There are 10505 cid made exclusively by combinations of major EFJ, and 1887129 made by combinations of major and minor EFG. There is a maximum of 40 (21 major+19 minor) EFG overlapping (major max 22, min 1; minor max 25, min 0).
