摘要
海洋测绘和陆地测绘的不同是,在海面以下对象对于常规的视觉测量方式而言都是不可见的,通常都是通过特定的科学技术,如无线电、声呐等技术手段加以检测。在GPS科技问世之前,即使是将几个具有不同相对地点的测量工作同时进行,在定位测量结果上也难免有较大的偏差。但由于现代GPS科技的发展,特别是将差分GPS技术投入测量应用领域之后,其定位的精确度已经得到了更专业的确认,适用范围也愈来愈广泛。
The difference between ocean surveying and mapping and land surveying and mapping is that objects below the sea surface are invisible by conventional visual measurement methods,and are usually detected by specific scientific technologies,such as radio,sonar and other technical means.Before the advent of GPS technology,even if several measurements with different relative locations are carried out simultaneously,great deviations in positioning measurement results are inevitable.However,due to the development of modern GPS technology,especially after the differential GPS technology is put into the measurement application field,its positioning accuracy has been more professionally confirmed,and the scope of application has become more extensive.
