division de petits polygones superposés

Question

<\/HEAD>Bonjour, <\/P> J'essaie de diviser des polygones qui se chevauchent en utilisant "split" des outils d'analyse, cependant plusieurs de ces polygones ne sont pas correctement divisés. J'ai vérifié deux fois que le nom de chacun d'eux est différent en créant un nom court (moins de 10 caractères), mais il y a plusieurs erreurs (plusieurs polygones dans un seul fichier *.shp). J'ai aussi utilisé model builder, et le résultat n'est pas meilleur. Je dois faire cela pour 3900 polygones, donc je ne veux pas le faire manuellement. Quelqu'un aurait-il une suggestion, s'il vous plaît ? Merci beaucoup.<\/P><\/BODY><\/HTML>

If you mean to split them into separate files, the Split Layers by Attributes might be what you mean.  Otherwise you may have to access the geometry of each shape separately, and do your processing on it.  It you could articulate what information you want extracted, that might make a difference.  Does it has something to do with the geometry, that geometry with respect to others?  etc?

I've been trying to attach the composite I produced, but I haven't had succeeded...or maybe yes, can you see the image? Thanks a lot.

Hi Dan, thanks for your reply. The overlapping features are in the same layer, although I've divided the layer into chunks some times to make it easier to split (save computer time). About the features: They are polygons corresponding to protected areas in the UK, very small, many about 14 ha. I need to separate each protected area to extract information from each of them separately. I attach an image that I hope makes it more understandable.
