Design and Characteristics of Submarine Mapping Sub-system MBMap
Tao Chun-hui · 2002
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.
