Intersections Between Bearings and Distances [ 0:30]
$15.00
Bearing-bearing, bearing-distance and distance-distance intersections are often determined by surveyors. Sometimes a special case of these: determining the perpendicular offset distance from a point to a line. These methods are taught using the law of sines and law of cosines. The learner must be familiar with basic trigonometric and geometric concepts to fully relate to the material covered here.
You will learn how to calculate…
• The locations of points on a line when only the proportionate distances between them are known can be done with coordinates, to explain COGO (coordinate geometry)
• A bearing-bearing intersection
• A bearing-distance intersection
• A distance-distance intersection
• The perpendicular offset distance from a point to a line
