Today the true north Great Circle of direction is the reference for direction measurement.Direction is expressed as degrees of Bearing angle or degrees of Azimuth angle.Fig.7.1 shows the Great Circle and illustrates the relationship between the Azimuth and Bearing Circles.
From Fig.7.1,it is seen that the Azimuth Circle increases in a clockwise fashion,beginning at due North,at 0°,and progresses around the Great Circle to 90° at due East,to 180° at due South,to 270° at due West,to 360° (or back to 0°) at due North.Thus,if a line was said to have an Azimuth of 160°00° (one hundred and sixty degrees and zero minutes),its direction
would be between due East and due South but nearer ro due South.
By the same token,it can be seen from Fig.7.1 that the bearing circle is divided into four parts:the Northeast (NE) quadrant,the Southeast (SE) quadrant,the Southwest (SW) quadrant and the Northwest (NW) quadrant.Bearings in the NE quadrant increase clockwise from zero degrees at true North to 90° at due East.In the SE quadrant,bearing angles increase counterclockwise from zero degrees at due South to 90° at due East.In the SW quadrant,bearing angles increase clockwise from 0° at due South to 90° at due West,and in the NW quadrant,bearing angles increase counterclockwise from 0° at due North to 90° at due West.
Because the Great Circle includes both the Azimuth and the Bearing Circles,it is possible to express a direction either in terms of Azimuth or Bearing and to readily convert an azimuth to a bearing angle,or vice versa.It is necessary to understand clearly this interrelationship because surveying computations are done in terms of azimuths when determining angular changes of direction of one line from another line,but the direction of lines is usually recorded in terms of bearings.
其实也就是bearing circle和azimuth circle两个的区别不懂

今天的正北方向的一大圈是一个参考指引方向的测量.方向表示为程度的轴承角度和程度的方位角.Fig.7.1显示了一大圈之间的关系,举例说明了方位和轴承圈.
从Fig.7.1,我们可以发现增加方位圈以顺时针时尚,从正北,在0°,该病的大圆周围90°在适当的东部,到180°在适当的南方,以7°西方国家在适当360°(或回0°)在正北.因此,如果一条线据说有一个方位为160°00°(一百六十个度和零分钟),它的指示
将之间应有东、南但接近罗依由于由于南部.
同样,也可以看到,Fig.7.1轴承圆共分为4个部分:东北(北东向)象限,东南(SE)象限,西南(软件)象限和西北(NW)象限. 轴承从零增长不象限顺时针方向旋转90度正北°在适当的东方.在SE象限,轴承角度增加从零逆时针方向度正南向90°在东方在西南象限,轴承增加从0°角顺时针方向旋转90°在正南向在适当的西部,在西北方向移动象限,轴承增加从0°角逆时针方向在适当的北至90°在适当的西部.
因为这个伟大的循环包括方位,轴承圈子,它可以表达了无论从方向或轴承和容易方位转换的方位到轴承的角度出发,反之亦然.我们必须了解这明明的相互关系,因为测量计算方面所作的azimuths改变方向角在确定的台词的角色,但一栏,线的方向上通常是写在轴承.
