水下地形信息微机处理系统

Underwater topographic information system(TIS)

江、河水下地形资料是进行河床演变分析的基础资料，这批资料常因系列长、区域范围大、坐标系统又不统一而增加资料分析整理的工作量，资料的利用率因此也大为降低．本文提出的水下地形信息微机处理系统，不但吸取了当今对地形资料整编的常用方法，同时结合了计算机发展的新成果，经大量图形的直观显示，展示了资料整编的成果．工作效率的提高、资料利用率的增大是十分明显的．

Topographic information,the basic measure for river deformation analysis,is characteredby its long series,extensive coverage, and uncorrespondence coordinate system.So,theanalysing and processing of the information is a tedious work and unfortunately leads to its lowerutilization.TIS proposed by this paper,which not only takes advantage of the ordinary methods,but also combines with the late development in computer, is able to produce and showmany innovative graphs and diagrams successed from the above information. Therefore, boththe improvement of research efficiency and the increasement of information utilization are expected to come in a sure way.
