<> When intersecting, lines of position are used to fix the position of an unmapped feature or point by fixing its position relative to two (or more) mapped or known points, the method is known as When resecting or fixing a position, the geometric strength (angular disparity) of the mapped points affects the precision and accuracy of the outcome. Resection is a method for determining an unknown position (position finding) measuring angles with respect to known positions. Accuracy increases as the angle between the two position lines approaches 90 degrees.Resection continues to be employed in land and inshore navigation today, as it is a simple and quick method requiring only an inexpensive magnetic compass and map/chart. endobj Objective: To introduce a three-point method combining the midpoint of the posterior cruciate ligament (PCL), the midsulcus of the tibial spines, and the midpoint of the anterior cruciate ligament (ACL) to determine appropriate tibial resection and component placing during TKA and to compare this method with Insall's 1/3 method.

The Snellius–Pothenot problem is a problem in planar surveying.Given three known points A, B and C, an observer at an unknown point P observes that the segment AC subtends an angle and the segment CB subtends an angle ; the problem is to determine the position of the point P.(See figure; the point denoted C is between A and B as seen from P). Today, with the advent of total stations/EDMs, the problem is greatly simplified. %���� to answer your question having Point A enabled as a backsight point and Point B disabled as a backsight point, the result for the resection point would be setting the orientation to Point A.

In this study, we will consider Three Point Resection in 3D with Distances. It is not to be confused with Glossary of the Mapping Sciences, American Society of Civil Engineers, page 451. The angle .
