Bonjour,
Merci pour ce retour. Je pense que c'est un problème de rendu de la carte : la surface est bien encore marqué comme foret dans la base de donnée. Je vais regarder le problème dans les jours qui viennent.
Pour ce qui est de la non conformité et de l'étiquette school:FR, auriez vous un nom ou une coordonnée de l'objet en question? Cela me faciliterait la correction du problème. (Je suis aussi preneur de plus d'infos sur le caractère non conforme qui a été introduit).

Sorry for your work, I am currenty splitting back the multipolygons. My goal was not to create to big areas but to remove most of the artificial lines that have no physical meaning.

Ok.
Just ntice that if someone modify the map, it is probably because a feature is mising on the rendered map. And on this map he/she will see the wood, so there will be no reason to add a new one.
Anyway I agree that the pultipolygon becomes quite complex : I will split this area into smaller ones (following physical features).

Hello, indeed the covered area is supposed to be unchanged.

What I didn't like with the previous mapping was the fact you had many lines drawn that have no physical meaning. It create unnecessary noise to map features under these lines. For example some rivers were difficult to see with these lines. I tried to create large areas which have river as boundaries.

However I am interested to know what you think was better in the previous model. If needed I can split the big area into smaller one, I just want to know why I should do so.

Sorry for bad comments. I know it is a bit rough but describing all the details of the changeset is time consuming and I prefer invest time to improve the map itself. So I prefer to give the global purpose of the changesets and let curious reader look in the changeset itself. On the other hand I appreciate feedback so I am open to know why I shoud improve my comments.

For information, this changeset was mostly about spliting very long edges of country borders (bigger than 15km) into smaller ones
Best Regards,
