几何大地测量几何大地测量geometricgeodesy利用几何方法测定地球形状、大小和地面点几何位置的工作。几何大地测量为测定地面点的几何位置,需进行水平控制测量和高程控制测量。水平控制测量方法有三角测量、导线测量、三边测量和边角测量;高程控制测量方法有水准测量和三角高程测量。一个国家的水平和高程控制测量都布设成网状,分别称为国家大地网和国家水准网。在大地测量中,空间一点的位置是用大地坐标来表示的。大地坐标用大地经度、大地纬度和大地高来表示。在一个国家中为了确定地面点的大地坐标,需要进行控制网的测量工作,通常在国家大地控制网的测量工作中,需要选择一个位置比较适中的三角点作为大地原点。在大地测量工作中精确测定大地原点的天文经纬度,并测定它的天文方位角。然后在参考椭球面与大地水准面最接近的条件下,通过弧度测量的计算,将天文经纬度和天文方位角换算为大地经纬度和大地方位角,同时求出该点的大地高。中国的大地原点设在陕西省泾阳县。在国家大地网中任一点的位置,是从大地原点起算的。
