A method is presented for determining the center-line stations and their right angle or radial offset from base-line stations. The base line and center line may be composed of simple curves and their connecting tangents. The method of solution is based on coordinate geometry. Coordinates of the base-line and center-line stations are computed as a part of the solution or provision made for their determination. The use of the method is demonstrated by four illustrative examples using worksheets arranged in a tabular form. The method could be readily programmed for solution by digital computer.
