Construction and Data Processing of D-evel Control Network with GPS Technology along Yangtze River Trunk
摘要
Abstract
Control surveying along the Yangtze River is a basic work of basin planning and port construction. As it is a long-distance and river-crossing measurement, needing the high precision, the conventional triangulation and trilateration methods can hardly complete the large-scale measurement work along the Yangtze trunk. The GPS technology posseses the characteristics such as high accuracy and fast measuring speed,and is easy and convenient for cross-measurement. Through the actual measurement, the application of GPS technology in D-level control of network along the Yangtze trunk, the proposal of measurement layout and the data processing methods are explored. It is proved by the practice that the measuring results are complying with the national standards completely.关键词
