Abstract: Informatization is a new trend in development of surveying and mapping system. The working efficiency of underwater topography has been greatly improved by the rapid development of multibeams technology, GIS technology and hydrological remote technology, while the cost of manpower and time has been reduced too. Based on the integrated application and development of these technology, the informationized underwater topographic surveying and mapping system is in construction. Taking the underwater topographic surveying and mapping work in inland water-areas as an example, this paper introduces the new development in constructing the informationized mapping system.

Key words: inland water-areas, topographic surveying and mapping, informationized surveying and mapping system

摘要： 信息化是新形势下测绘体系发展的新趋势。多波束技术、GIS技术及水文遥测技术的快速发展大大提高了水下地形测绘的工作效率，同时降低了工作中人力、时间成本投入。这几项技术的集成应用与发展，正在努力构建水下地形信息化测绘体系。笔者以内陆水域的水下地形测绘工作为例，介绍水下地形测绘在信息化测绘体系构建过程中的新发展。
