例如，当我们徒步走在空旷的乡村上的时候，我们发现使用地理方位非常有用。 但是当我们描述小规模的空间时，我们完全以自己为中心的坐标系进行交流。

We find it useful to use geographic directions when hiking in the open countryside, for example, but the egocentric coordinates completely dominate our speech when we describe small-scale spaces.

将雷达转换为姿态角不断变化的目标体坐标系下一点，研究雷达视线在目标体坐标系下的方位和高低角。

Considering radar as a point in variational target body coordinate, we can study the azimuth and elevation of line of sight of radar in target body coordinate.

根据道路设计信息，推导出线路坐标系下任意中桩点的坐标计算公式和横断面方位角，由计算得到的横断面方向指导野外GPS断面测量。

Based on road design information, we derived coordinates of arbitrary points in the pile and cross-sectional azimuth which may guide global positioning system (GPS) surveying in section surveys.
