| Re: findout centre of location from a set of long and lat
One approach is a simple mean. This will give you the centre of the points - but not necessarily the centre of the polygon defined by the points. This is because you might have a shape with lots of points on one side, but only a few on the other.
A simple mean is usually "good enough" unless you are near the poles, the International Date Line or high latitudes.
