潮汐修正 meaning in Chinese

correction of tide

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。
