Accuracy Investigation of Three-Point Resection Methodusing Known Points Distribution in Four-Quadrants

Abstract

This paper presents a simple way of finding the accuracy of three-point resection problem. The main idea is to distribute known points in four-quadrants and compute the coordinates of the resected point (P),then investigate the affection of known points positions in one quadrant or combination quadrant for the accuracy of resected point (which is a new idea in the literature). This article aims to find outthe affections of distribution control points in different quadrants on the accuracy of the resected point, and also choosing the best positions of the three-points interms of their positions in one quadrantor their positions in combination quadrants. The relative positions of the known points and the resected point are playing the main role to decidethe accuracy of the resected point. Thestudy of the relationship between relative positions of unknown point will be explained in detail, other known-points and the accuracy of the unknown point will beintroduced,and the positions of known points (Distributed in quadrants) of having the best accuracy of the resected point will bedefined.
