Intersection Angle/Azimuth Angle Calculation - Sokkia CX-62 Operator's Manual

25.7 Intersection Angle/Azimuth Angle Calculation

The coordinates of a cardinal point, an arbitrary centerline peg, and width pegs
can be found from an intersection angle, curve properties, and either the
coordinates of 1 IP point of intersection or the azimuth angle from the BP Point to
the IP point.
It is then possible to proceed with the setting-out of the cardinal point, centerline
peg, and width pegs
