I think it is the project that is financed by the Flanders government. See https://whc.unesco.org/en/wh-gis/
"For the pilot phase, polygons for World Heritage properties in the Europe and North America region were collected, analysed and integrated into WHOMP. The second phase focuses on the inclusion of World Heritage sites in the Africa region, with a view to extending the platform to properties in all regions in subsequent phases. "

This is great! And they must have a lot of fun in doing that.

Maybe this endeavour will change the view that we have for some WHSs? Since they seem to have already well mapped BeNeLux, I see now that the Dutch water defense line apparently is a megacorezone stretching through half of the country, instead of punctiform series...

For that matter looking at Italy, I've traveled across the Po Delta by train and hadn't even realized it. Still won't count it until I do a proper visit there, or even better, to Ferrara.

Right, that one is probably one of the unclearest WHSs in Italy, and even beyond. I'd say it is even two WHSs squashed together just for geographical vicinity, with this weird emphasis on Diamantina. So the mapping will be really useful to clear up cases like this!

I think the reason for this is that these polygons already exist in an easy to access and stadardised format as part of the World Database on Protected Areas (WDPA) .
It was set up in 1981, and presented on the website protectedplanet.net since 2010.So very easy for them to quickly transfer over to this GIS project.

I think a lot of Iberian rock art drifted off to sea near Alicante...

The problem with these is that they are the official coordinates displayed on the UNESCO website.
The rock art included generally is so obscure that it doesn't show on Google Maps.

But if somebody else manages to find them (or has another source): please!

Further to this
a. The entire sequence of locations for this WHS from 105 ( Rock Art of the Mediterranean Basin: Arroyo de martín Pérez) to 129 ( Rock Art of the Mediterranean Basin: Garganta de la Hoz X) is incorrect
b. They are all in Jaen province around the area of Aldeaquemada town - but other locations in that province numbered earlier seem to be OK.
c. All of them have a longitude on UNESCO (and carried forward by us) of 0 degrees and between 14/15 minutes. The degrees should all be 3 degrees West
d. I had hoped that simply altering the degree figure would give a correct answer - as far as I can see it does not! (please check!)
e. I have looked at a range of other sources using the names of those caves missing their cooridnates. Some are reasonably identifiable and we could probably find a set of coordinates for them... a number of the "caves" are so close to each other that our map scale couldn't differentiate them any way - e.g Garganta de Hoz I - X (1 to 10)
f. So leave these locations without a map link? Have caught up with this being the way we show that we don't have a location!!! e.g as per some Asante locations. How many of these are there across AL inscribed locations. If not too many it could be interesting to have a list for us to work on?
g. Do we not have the UNESCO location number on our dB - for WHS with small numbers of locations the fact that it doesn't display doesn't matter too much -but for ones with many locations it makes comparison with UNESCO rather more difficult

I DO have coordinates for the Centro de Arte Rupsetre de Aldeaquemada - if one was wanting to search out the caves in the area one might be advised to go their first - but to show it as THE location of a cave would seem to give an incorrect impression!

Jasam has a corrected set of them I think, so perhaps he can provide them.
If I remember correctly the ones in the sea are the result of something really simple, like using an adjacent square on the Spanish mapping system.

I don't have the exact coordinates for these but I can tell you that they're all situated in Aldeaquemada, northern Andalucia. They're a 3-hour drive away from me, I should go someday and get back to you!

It's a little bit more complicated than that, but yeah. If I remember correctly, UTM ED50 coordinates were converted as ETRS89, or vice versa. But even so, you always end up like 200 meters away, which is a lot when you're on the ground!

Or we could have a meetup there one day and check them out all together :) Most of these locations are classified as "easy" to reach.

I'd love that!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Rock Art of the Mediterranean Basin:

a. So - if there is no "generic" way for Jasam to alter all the incorrect coordinates I have had at go at finding them individually.

b. Of the 25 location numbers 105 to 129 only 107 and 111 have correct coordinates on UNESCO (and hence on our map). If you look at the coordinates of the group on the UNESCO web site they are the only ones with a Longitude of "W 3 nnnnn" rather than "W 0 nnnnn" . So we need to find coordinates for 23 locations.

c. I have discovered a web site titled "Jaen Escondido" which actually has a photo of EVERY one of the Abrigos/Cuevas in this group!! I have provided below a the link to each. Unfortunately that is about all it does show - it doen't provide any coordinates, descriptions of how to get there etc!! The pictures might help you if you are looking for them however!!

d. MapCarta has proven very useful. Unlike Google Maps it has a number of the Abrigos/Cuevas shown on its maps. e.g Here . I have been able to find 11 of these. So that leaves 12 (23 - 11) more to find.

e. That is not as bad as it sounds because these consist of only 2 groups of caves which both share names with just a different reference number There is a group of 2 - Cimbarrillo Maria Antonia 1 and 2 and a group of 10 Garganta de la Hoz 1 to 10 (the description use Roman numerals). The incorrect UNESCO coordinates are even the same within each group and I think we can assume that the real coordinates are also very close together. I.e the reality is that we are short of 2 sets of Coordinates for the 12 locations.

f. Unfortunately I just cannot find these so far. I even know where the Cimbarrillo pair are as it is the name of a waterfall and river which is shown on Mapcarta. Over to someone else!!! They are all within a few kms of the others in this group.

Thanks a lot, Solivagant. I will add the ones you found.
For the time being, I will leave the other ones blank (not in the sea anymore, but with an id)
