Just introduced "Community Identified Locations" showing on our maps, and - while looking into which locations to change status from "official" to "community identified" - I already feel that they need a proper definition.

My first take:
Community Identified Locations are coordinates that point to core areas of (T)WHS, where
- no coordinates at all are given for the site/the component on the UNESCO website, or,
- the coordinates given on the UNESCO website are clearly wrong (as far as you'd show up at a totally different place; not by a few metres)
- (except, possibly, - where the location is obvious)

So these are our attempts "to improve" where the official sources are lacking. Making the distinction between "Official UNESCO location" and "Community Identified Location" tells you something about the reliability of the coordinates given. The latter group still should be viewed as best guesses.

I have browsed through the older posts in this topic a bit to get an idea for examples.

What I did notice is that some locations we identified (such as in St Petersburg) are now fully covered on the UNESCO website.
Others still are not, such as the Antonine Wall or the odd location of the City Walls of Thessaloniki.

The only 2 that I have set to community identified so far are the Lower Valley of the Omo and the Asante Traditional Buildings. I will start to make a list of other problem children and verify their current coordinates status at the UNESCO website.

Starting the list...

- The Persian Garden - Fin Garden - still wrong on UNESCO website
- Several locations of the M'Zab Valley - still missing on the UNESCO website, we have them
- My Son - no coordinates on UNESCO website and vague map (but "obvious" as per the criteria above?) (same for Ban Chiang, Sangiran)
- Taxila: UNESCO website still misses coordinates for 1 location
- Frontiers of the Roman Empire: Antonine Wall still missing at UNESCO, but they have more locs than we overall (check)
- Ancient Merv: has 33 locations; we have 27 mapped, UNESCO has 25
- Silk Roads (Chang'an) - UNESCO now shows all 33 locs
- St. Petersburg - UNESCO now shows all locs: has 126 where we have 112 (explained here)
- Coa Valley - has been fixed by UNESCO
- Elvas - OK now with UNESCO
- Echmiatsin - still wrong for the cemetery and Gayaneh church
- Kii mountains - now ok with UNESCO
- Tiya - no official map or coordinates, lonely dot on UNESCO map is a bit off
- Spiennes: no coordinates on UNESCO
- Stari Ras: still off on UNESCO
- Kujataa: still seem different, needs a recheck
- Rock Art of the Mediterranean Basin: UNESCO has 758, we 715 (and have been more specific at several (see also this)
- Mexico City - OK now at UNESCO
- Thessaloniki - still wrong
- Daphni Monastery - still wrong
- Wooden Churches of Southern Malopolska - still wrong
- Aigai - still at the old spot which is illogical
- Franciscan Missions Sierra Gorda: have improved
- Wooden Churches of Maramures - Plopis still seems incorrect
- South China Karst - our locations seem a bit more precise but is this enough?

For me, a community location is a either a correction of the official location (I fondly recall the 0°,0° location). Or it's a location that's plain missing from Unesco.

Technically, Official and Community locations get shown on the larger maps, while PoIs are restricted to the site itself.

Apparently, Mexico City has 4 sites in total, one of which is the town of Mixquic and its chinampa zone, which is what the UNESCO website suggests.

Thanks for reporting! I have added them

Continuing with the list...
- 4 early bulgarian sites: they have maps now and locations shown at UNESCO website seem correct
- Churches of Goa: no coordinates on UNESCO website yet
- Nord Pas de Calais: this is where we found the 1 more in the nom file + other locations have been corrected (a, b)
- Slovak Wooden Churches: some locations a bit off (+100m)
- Migratory Bird Sanctuaries: UNESCO list is now complete, has 12 where we have 11 (check)
- Rainforests of the Atsinanana, Ranomafana: UNESCO location is still weird
- Bamiyan Valley: 3 incorrect locations stay unchanged
- Gondwana Rainforests: all present now
- Epidauros: is OK, has map,1 fairly large core zone
- Church of Probata (Churches of Moldavia): still very wrong, and maybe more churches with issues
- Mtskheta, Jvari monastery: is OK
- Villages with Fortified Churches: Biertan still wrong
- Mérida: most are a bit off, too far for good use
- Lower German Limes, Matilo - a few hundred metres off
- Pile Dwellings, Lugana Vecchia: OK now
- Stone circles of Senegambia: still wrong
- Minaret of Jam: 3 locations missing coordinates at UNESCO website
- Lope Okanda: UNESCO now shows 3 locations, we need to update (done)

End of list
