The Layout and Precision Analysis of GPS Control Network and Trigonometric Leveling for XingYi Xiao LongTan Water Resources Engineering |
| |
| Abstract: | The paper discussed the GPS control network layout and the way of trigonometric leveling with distance measurement by total station. And it focused its attention on analying the accuracy calculated of GPS control network and height survey. The rules for relevant tolerance of specifications must be complied with during measuring. The paper also confirmed the reliability of the GPS control network for water resources engineering in the mountain area. It verified the rule that the fourth-order leveling can be replaced by trigonometric leveling with total station distance measurement. |
