Data review: Gadm Australia

[timrobertson100]

The Australia data for the gadm filter looks unexpected.

1. The gadm site for NSW shows many areas, but they are not available in our search fitler. That could be that GADM is missing an area though and showing the children, because we have an area in NSW that gadm doesn't have.

2. ACT seems to have no children which is unexpected when compared to gadm

1. According to our data NSW has 153 sub-regions and the GADM page shows 199: SELECT COUNT(*) FROM gadm3 WHERE gid_1 = 'AUS.5_1' and gid_2 IS NOT NULL AND gid_3 IS NULL; returns 153
2. According to our data ACT has one sub-region:
   "id": "AUS.2.1_1", "name": "Unincorporated Australian Capital Territory"
   Which has no children in our data, API: Unincorporated Australian Capital Territory, SQL: SELECT COUNT(*) FROM gadm3 WHERE gid_2 = 'AUS.2.1_1' and gid_3 IS NOT NULL;

The GADM version available for download on gadm.org (gadm36_AUS_gpkg.zip → gadm36_AUS.gpkg) does not include these regions. There is a note that "Version 4 will be released in April 2020".

We can contact GADM and ask when the next release is, but someone at the ALA might be better able to check what's visible on gadm.org is reasonable, and point the GADM maintainer to any open data sources for anything that's still missing.

Similar/same data is in GADM 4.1. I think the maps on gadm.org show an old version.

Try select fid, gid_1, name_1, gid_2, name_2, gid_3, name_3 from gadm where gid_0 = 'AUS' order by gid_1, gid_2; on dev_eez.

There aren't any level 3 divisions.
