Abstract
With rapid development of GPS, RTK has reached a mature stage, and is gradually applied for survey. The essay introduces employment of RTK at lake volume measurement of Qinghai lake for the first national census for water, approaches a subject about data processing methods for underwater topographical survey and advantages of field survey. Its application illustrates that using RTK has already changed the way of underwater survey, realizing high precision and efficiency, and reducing labor intensity of work. Continuous development of RTK will change survey methods, such as control survey, vertical cross section measurement and construction lofting as well.关键词
