Specifications for hydrographic survey
海道测量规范
The main purpose of seafloor surveying is to obtain digital sea charts , which are developed by means of mosaic technique under the constraints of hydrographic surveying principles . therefore , mosaic technique is of fundamental importance in surveying processes
该系统的最终成果体现就是得到符合海道测量规范的数字地理海图和三维地形图，可见拼图技术在整个系统中具有极其重要的地位。
Applying the information extracted from numerous hydrographic data of field trials collected by h / hcs - 017 , the first set of multi - beam swath bathymeter developed in china , a series of mosaic techniques have been carefully studied in this thesis , including digital terrain model building , statistical error analyzing , hydrographic data mosaicking as well as tides correction and projection of the earth coordinates . finally , standard digital sea - charts and three dimensional seafloor images are successfully developed that are consistent with hydrographic surveying principles
本文利用我国第一台h hcs ? 017型条带测深仪的测量数据进行拼图技术的研究，主要研究的内容有：利用分带原理对深度数据进行潮汐修正，得到瞬时海面的深度数据；对测深数据进行误差分析处理，去除野值；将多波束数据进行坐标变换及投影转换后构建数字地理模型，进而根据海道测量规范绘制标准海图。
