摘要
详细介绍了一种长宽比例尺不一致的航道扫测图制作的数学模型和制作方法,采用计算机语言编制的软件对这种航道扫测图的制作方法予以实现,并且通过我国北方某港口航道扫测的工程实例进行了验证。
An unequal scale chart in length to width of channel sweep-surveyed is developed. The mathematic model and procedure of charting are introduced. The chart of channel sweep-surveyed is produced by use of computer software, and the method of charting is verified by an engineering example of a seaport in northen China.
