Base on sufficience to use potential of existing equipment,this paper shows the main characteristics of automatic system,and its application in marine integrated survey,such as marine gravimetric and marine magnetic.

Research on intelligent pre-warning mechanism based on marine integrated observation platform;

The object of marine survey is the seabed covered by seawater,so the methods and instrumentataion used for the marine survey are greatly different from those used for the land survey.

Based on an analysis of the characteristic of marine surveying, a robust method for the detection of abnormal data (include blunders) in marine measurements is proposed in this paper, which is called the robust interpolation comparison test based on robust M estimation by an iterative calculation procedure.

Based on the universal software AutoCAD, the integrated system on digital single - beam hydrographic surveying and charting is discussed in this article.

During the last decade,significant advances have been made in the study of hydrographic surveying technology in China.

Based on the analysis of the latency effect between positioning and sounding in marine surveying,the detecting and correctional methods are presented in this paper.

Based on the analysis of the present status of the establishment of depth datum for marine surveying in Hainan,this paper put forward the concept of establishing the from curve model of theoretical lowest low water around Hainan island,and analyzed the practical methods for establishing the model.

During the last decade, significant advances have been made in the study of hydrographic surveying technology in China.
