| Abstract: | With the all-around development of GPS technology,it has changed the traditional surveying methods.Regarding the horizontal control network with high accuracy,GPS height also breaks through the technological limit and reach horizontal control accuracy.In this paper,it point out that the adoption of GPS fitting height in the relatively smooth surveying area,which replaces the traditional fourth order leveling height,can popularize the application of GPS three-dimensional technology so that efficiency can be better achieved. |
