【摘要】 GPS技术的全方位发展,改变了传统的测量方法,在提供高精度的平面控制网时,GPS高程也有技术上的突破,达到相当于平面控制的精度。对此提出局部在较平坦测区,用GPS拟合高程代替传统的四等水准高程,从而推动GPS三维技术的新发展,使其具有更好的时效性。更多还原

【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.更多还原
