ha, ha!!,<div>My knowledge come from Maths ,and certainly not from Postgis!. The concept of Convex Hull (in algorithms and math fields) is always applied to set of points and I remember there was a big challenge to find a good method for lines (some years ago). But I don't mind Math anymore, if this function works to solve my problem, it will be ok for me.</div>
<div>I will let you know later about my results.<br><br><div class="gmail_quote">On Mon, May 3, 2010 at 11:29 AM, strk <span dir="ltr"><<a href="mailto:strk@keybit.net">strk@keybit.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
