The invention relates to the marine surveying field, which is a systematical error testing and adjusting method of a marine surveying line net system. In the method, the first step is data acquisition, marine surveying line data which is obtained by a conventional measuring line method is transmitted in a computer by a data wire. In the second step, a computer data processing system performs the error detection of measured data of the marine surveying line net by a rank defect network adjustment principle: first, pictures are visualized and are edited, and a difference value of a junction is obtained, meanwhile, a difference value pie diagram of the junction is plotted, and the parameter results are obtained by the difference value circle analysis and the compensating computation. In the third step, tested testing data errors are adjusted, and systematic errors are corrected. The invention improves the precision of testing data of an entire region, avoids the resurvey and saves the measuring cost.

The invention belongs to the technical field of surveying and mapping, and discloses a high-precision laser range finder and a use method thereof. According to the scheme, high-precision range finding can still be kept in a field environment. A range finder body can be adjusted before range finding by arranging a sensing column which deforms to a certain degree in a heating state, and shaping is carried out after adjustment to improve the positioning effect on the range finder body. Meanwhile, after being heated, an inner deviation ball in the sensing column is converted into an adsorption locking state from an original free movement state between the inner deviation ball and a point extension column, and then deviation sensing of the range finder body is achieved. Once deviation occurs, the inner deviation ball is inclined and a visual prompt is given. The deviation can be found and handled in time at the initial stage of the deviation, so that the phenomena of error accumulation and enlargement, even re-measurement and back-measurement are avoided, and high-precision of range finding is ensured.
