Approximate Angular Directional Representation of Geometrical Objects

Abstract

Consider a scenario where a military intelligence ground-operative encounters an array of radars during a reconnaissance mission in enemy territory, where the shape of the array is important to determine its purpose. However, he does not have requisite gadgets to make any accurate positional assessment about the array. He starts noting down the approximate angular direction of each radar from its previous radar position in the array, with respect to the North (say, by observing the Pole Star in the sky). Thus, he tours around each point in the array and records this information. Obviously, without an appropriate gadget the angular directions estimated will be very qualitative in nature. In this paper we propose a scheme for, and discuss the related issues involved in, such a qualitative angular representation of geometrical objects. Primarily we are concerned here in studying the shape of a polygon that could be encaptured using the Star-ontology representation scheme developed in the literature.
