The Research About Quick Acquiring Technology Of Waterway Hydrological Information

The project is based on implementation of a national strategy on the development of inland water transport, inland shipping intelligence to accelerate the pace of development of major principles for the Yangtze River complex characteristics of the geographical environment, through the current status of the Yangtze River Waterway topographic survey techniques and analysis problems, the study excluding gross errors automation bathymetric data and interpolation techniques, combined with the water level of the Yangtze River waterway station data, real-time automated correction bathymetry data, while channel topographic survey research integration technology inside and outside the industry to achieve rapid acquisition and processing of information fairway terrain elements.Yangtze River waterway for electronic chart functional diversification, service intelligence needs, according to the channel fast data acquisition and pre-terrain technology solutions, research and development fairway terrain feature information fast acquisition and pre-processing software systems, real-time integration of multi-source data,bathymetric data coarse Poor automatically removed, the water level automatic correction,terrain mapping of integration of operations, abnormal screening data analysis and many other features, combined with the production of electronic production system of the Yangtze River waterway map, and ultimately achieve rapid updates and application service elements waterway terrain information.By studying this project to further enhance the real-time electronic chart system data channel update speed and accuracy, providing safe and reliable reference for ship navigation, achieved good economic, social and ecological benefits, with good promotion prospects wide range of applications and technology portability of their research will promote the development of domestic water technology.
