单波束水深测量的定点取样技术实现

使用定点取样技术,实现快速生成批量定点取样文件、批量绘制定点断面取样图,最终生成定点取样后的水深图的设计思路以及实现方法。此技术在保证不损失水深精度的前提下,按照规范取样距离及用户指定的特征点位置(如航道设计坡脚)准确地生成水深点。不但用图单位使用方便,而且优化了水深图图面质量,提高了美观度。

Realization of Fixed-point Sampling Technique in Single-beam Bathymetry

This paper introduces that the Visual Basic Studio 2010＋AutoCAD 2012 as the development platform,the usage of fixed-point sampling technology ,the design idea and realization method for rapid generation of batch fixed- point sampling file ,batch charting of fixed-point sampling section and getting sampling depth chart finally. In order to ensure no loss of depth accuracy ,this technology is in accordance to the sampling distance of standard and the position of point that user specified （ such as the design of channel slope ） to accurately generate depth point, which is convenient for the users ,optimizes bathymetric chart quality and improves the aesthetics of the map.
