1. A method of establishing a fence network, the fence network comprising a plurality of fence nodes in communication with each other, a plurality of fence vertices defining a geographic fence, the method comprising: configuring the plurality of fence nodes; setting up a coordinate system to determine a position of each fence node of the plurality of fence nodes; for each fence vertex setting a location marker at a position of the fence vertex; using the location marker to register the position of the fence vertex at least by: computing a convex hull from the position of each fence vertex; and determining whether any fence vertex is located inside the convex hull, wherein when a fence vertex is located inside the convex hull: calculating all possible orderings of fence vertices consistent with an ordering of the position of fence vertices located on an exterior of the convex hull; and defining sides of the geographic fence by selecting an order having a greatest minimum acute angle which is less than a predetermined threshold.
