Looked at Canada today.

Did the following:
Landscape of Grand Pré
Wood Buffalo National Park
Miguasha National Park
Head-Smashed-In Buffalo Jump
Joggins Fossil Cliffs
Old Town Lunenburg
Red Bay Basque Whaling Station
Gros Morne National Park

The rest was too difficult to do manually, as they follow the meandering flow of Canada's many rivers. Also, some Canadian WHS were early entries and have no good maps yet.

Managed to bring the total of Core Zones to 99 today.

New are:
Crac des Chevaliers and Qal'at Salah El-Din
Stone Circles of Senegambia
Harar Jugol
Asmara
Historic Town of Grand-Bassam
Atapuerca (by Catoplayer)

What I learned from this batch is that it isn't really worth it to focus on the very small cultural WHS. For a site like Crac des Chevaliers, a dot or an icon is just as good as a core zone at this point.

So will continue with the natural sites, the national parks. Have done what I can with those in Africa, will now move to South America.

Did the first 10 of South American parks today:
Iguacu
Iguazu National Park
Manu National Park
Rio Abiseo National Park
Huascaran National Park
Sangay National Park
Los Katios National Park
Noel Kempff Mercado National Park
Canaima National Park
Central Suriname Nature Reserve

Will take a break now (I have a good excuse: I am travelling next week)

Found some time to do a couple more (I enjoy the meditative aspect of the painting by numbers...):
Cerrado Protected Areas
Los Glaciares
Lençóis Maranhenses National Park
Peninsula Valdes

The only one of note is the Cerrado Protected Areas:
1. As its official map, the one from 2001 is shown on the UNESCO website. However, a minor boundary modification was approved in 2019, extending the Chapada park by some 3%. A clear map was submitted with the boundary change and the park boundaries on the OSM map also correspond with this new outline. I have used these new boundaries.
2. Although the site consists of 2 components (Chapada dos Veadeiros and Emas National Parks), the Chapada dos Veadeiros part comprises 2 separate areas. The second area is smaller, but not so insignificant that it is like a seastack which we have seen popping up at Skellig Michael.

Added Rio de Janeiro today.

This one comes with a slight warning, as the accuracy level isn't as good as I managed to achieve with the previous ones, since the only available map is a mere sketch. But I added it anyway, as it is a fairly complex WHS to understand scope-wise.

There are 4 components. The 2 westernmost are clear. The one in the middle is OK-ish, but suffers a bit from a myriad of park and reserve border lines at the northeast side, where it is unclear which one is meant. And finally, the city area. Roughly OK, but I cannot fully see how far the core zone extends inland. I think I got it right.

If you see improvements to be made, let me know and I can adjust it. The included areas are described in wording in the nomination dossier.

I think you miss the botanical garden in this component. It's marked on the map and is even included in the name of the component.

You are very right. I will change it.

I did Pantanal.
It consists of 4 parts. The boundaries of the National Park are clear, but those of the 3 private reserves included as well, not so much.
I have added them to the best of my abilities, resembling the shape on the official map and also checked with Protected Planet.

In addition to the sketchy official map on the UNESCO website, there are better ones on pages 44 and 49 of the nomination file.

Some more Latin American ones I added over the past days:

Maya Site of Copan (tiny, tiny core zone)
Río Plátano Biosphere Reserve (the first I used from Protected Planet)
Archaeological Park and Ruins of Quirigua
Tikal National Park (a simple square!)
Ischigualasto Talampaya Natural Parks
Galapagos Islands
Pampulha Modern Ensemble
Paraty and Ilha Grande (very hard, took me 1.5 hours...)
Central Amazon Conservation Complex

125 covered now, just over 10% of the total (however, according to UNESCO during the last WHC, 48% of the sites still have inadequate maps, so the coverage we're working towards may be 52%).

I think we should count where core zones actually help. I think there are several, where they aren't that key. Or where PoIs achieve the same thing, e.g. The Rideau Canal or Dorset Coast.

When selecting the sites, I indeed look at how "helpful" they are - but even a tiny one like Copan can tell you something.
Cultural landscapes are particularly hard, as they often have no boundaries that are recognized outside of the WH world (in contrast to national parks which are). But they would be helpful to have.

Another interesting case is Guanacaste.
It should at least become part of our 'Incorrect Number of UNESCO locations' connection, as although the whole area is "almost contiguous" (they included some corridors to connect the different parks), Junquillal is clearly separate from the rest.

And there is another odd "component". On the map after the extension, a small separate area in the south has suddenly appeared. It has no name except for an access point named Puesto La Virgen. It has no reference in the nomination dossier. It is also not displayed on the Protected Planet map (but that one isn't perfect anyway). Someone with an idea what this could be? I have now omitted it from the core zone map as it was impossible to pinpoint.

As you can see I moved from Southern America to Australia. Australia's maps are generally very good. The only issue is that the designated areas are often very complex, with multiple enclaves. I had to skip a few.

Unfortunately the map quality of Australia isn't continued in New Zealand:

- Tongariro: has an enclave in the far north and a railway line cuts the southern tip in two halves.
- Te Wahipounamu: a colourful mess of a map, no exact borders that are reproducible on a regular map; the one at Protected Planet is incorrect as well
- Subantarctic islands: poor map as well but clear what they mean and shown on OSM; here however I have the issue that the maps show New Zealand twice on a world map, once at the far east and once at the far west, and especially the 2 westernmost Subantarctic Islands pose a problem. I might remove it again for more clarity.

A few notes on Indonesia:

- Komodo: I followed the boundaries as shown on the official map. The current Komodo NP is slightly larger (extends further north), but no boundary modification has ever been proposed/approved
- Lorentz NP: I used the map from Protected Planet as the northeast was difficult to draw
- Ujung Kulon NP: Protected Planet here misses Krakatau (as it is a separate NP from the main Ujung Kulon)
