Obstacles in curve ranging—the optimum point approach
Oliver C. Ojinnaka · Australian Surveyor · 1991
The theory of a recently developed method of curve ranging known as the Optimum Point Method (OPM) is reviewed. Among the advantages of the OPM is its ability to provide on-the-spot solution to most types of obstruction encountered in the field. This facilitates a continuous and uninterrupted setting out process irrespective of the spread of obstacles and without loss of accuracy at any point. The paper highlights the different types of obstructions which could be encountered in the field. The techniques adopted in overcoming these obstacles, with the aid of the OPM, are also discussed. It is verified that the OPM gives a ready solution to most types of obstructions which usually confront the surveyor in the course of staking-out operation.
