. Criteria for the classification of hydrographic positioning Oceanography. Figure Geometry of an Azimuth-Azimuth Position Consider the following as an example of a blunder associated with range-range geometry. An offshore position is to he determined by the intersection of two electronic LOP's generated from transmitters located on known shore stations. The vessel is working west of a shoreline that runs generally in a north-south direction.

An offshore position is to he determined by the intersection of two electronic LOP's generated from transmitters located on known shore stations. The vessel is working west of a shoreline that runs generally in a north-south direction. As the hydrc- grapher faces the stations from sea, the southern shore station is mistakenly identified as left and the northern shore station as right. The resultant offshore position will plot to the east of the base line. This blunder is readily detected and can be easily remedied. Not all types of blunders are so easily detected. Suppose an offshore position is to be determined ty a 22.
