I started making an “Natural Earth alternative” based on OSM, called “country-levels”. It uses ISO country codes and Wambacher’s land polygons + Wikidata for population, data fixes, etc… It’s an open source project under MIT license.
My problem is that Portugal has a region missing from Wambacher. I believe it is happening because this region is tagged as admin_level 6, whereas all regions on the same level are tagged admin_level 5.
But I didn’t want to fix it myself, as I am not familiar with the Portugal admin levels. Can someone have a look what is happening? Is it as simple as changing to admin_level 5 and waiting for the next regen? BTW, Wambacher’s website says timestamp is from January, did the project not update since that time?
