[h=2]Hello everyone,[/h][INDENT]
     I turn to you because I am facing a big problem (for me anyway).

     I'll try to be simple and concise.

     I have a set of linear and planar point data. In large quantities!,  About thirty. shp sometimes containing up to 250,000 items per table.

     I try to cut a global polygon around this dataset.

     If anyone can help me in my approach. I thank you in advance.
