ABSTRACT
Intersection surveys have been used in geomatics in situations where accessible points are separated by large distances, or when some points are accessible and others inaccessible. Intersection problems are solved by realizing triangles between two stations with known positions from the location where the observations are made. The law of sine is used to solve oblique triangles. As a computation practice, the intersection method is used where two lines had known coordinates and direction. The coordinates of the unknown vertex are determined by intersection and then the results are checked by determining the same coordinates of the unknown vertex from another known vertex.
