Hello,

What I'm basically trying to do for a week :
Draw a polygon area from a cloud of points with coordinates.

I have clouds of points with coordinates. Each cloud is a group of 30
to 100 points.

What I want : is to determine the most external points, or
peripherical points, so I can add them to a <LinearRing> so I can draw
a Polygon area that will includes all the points of the cloud.

Is there an API way to do it? Or should I found a solution trough
basic maths?

Thank you for your help.
