摘　　要：简要论述了基于图层面向对象的海底地形成图子系统的设计思想和主要特点。该系 GIS MBMap 统以处理矢量数据为主,但同时顾及到栅格数据。该系统最大的优点是基于海底数字地面模型进行自动化成图,不仅能够以变间距来绘制等值线,而且基于图形的内外边界建立等值树,从而实现等值线的快速矢量充填,另外,还基于技术实现三维仿真图的绘制。系统不但提供了常规的编辑制图功能, OpenGL GIS 还提供了人机交互矢量化功能。该系统还可直接基于电子地图进行导航定位。该系统的成功设计和 GPS 实现,可望为开展“数字海洋”的研究提供原型。The submarine mapping system MBMap is discussed in brief, which is based on the graphics layers of GIS. This system processes the vector datum and grid datum. Its excellent feature is the automatic mapping based on the submarine DTM. It not only creates the contour map with variable contour level, but also builds the contour tree based on the map boundaries, thus displaying the color filled vector map quickly and accurately. In addition, it draws the 3-dimensional map based on the OpenGL technology. It provides the routine editing and mapping functions of GIS, and also the vector function through man-machine conversation. It can be directly applied to the GPS navigation as well. Because of its successful design and achievement, it will possibly provide the prototype for the study of Digital Ocean.
