Direction on the sphere is measured by azimuths . 地球上的方向是通过方位角测定的。
The length and azimuth of one side at each junction point is first decided on . 每个交叉点上的一条边的长度和方位角是一开始就决定的。
The error in azimuth must be controlled by astronomical observations for azimuth(and longit ude) . 方位误差必须观测天文方位角(及经度)来控制。
It seems only to be of possible interest in that some computation formulae are deduced in terms of the geodesic and its azimuth . 可能关心的,看来只是某些公式是用大地线及其方位角来推导的。
