摘　　要：结合目前数字海图的三维可视化应用需求,对不同类型的数字海图从数据获取、处理、三维表达、可视化管理和应用等方面进行了分析。主要介绍了栅格海图的可视化显示,shp矢量海图图层的自动加载和三维符号化显示,基于海图控件的S-57的SENC海图的动态、多要素海图信息影像化三维表达和管理等方面的内容,为海洋测绘成果应用、测绘信息保障提供新的技术手段和应用平台。Combined with the application requirement of three-dimensional visualization of digital chart and aimed at different kinds of digital charts,this paper presents the analysis on data acquiring,processing,threedimensional expression,visual management and application. The three-dimensional chart application is introduced including the visual display of grid chart,automatic space loading of shp vector chart layer and threedimensional symbolization display,dynamic multi-elements transform-to-image three-dimensional expression and management of S-57 digital chart based on chart control and so on. Thus the new technology and system are provided for the application of hydrographic surveying and charting production and mapping information guarantee.
