问题描述
大家好，
如果有人知道在给定纬度和经度的情况下确定方位方向，那将很有帮助.我不太明白逻辑.
这是一个例子.
要点1:
纬度:41°15''18.000000"N
经度:76°00''0.000000"W
要点2:
纬度:41°19''7.097720"N
经度:75°54''55.972300"W
计算的正向和反向角度/方位角为:
向前角度(从点1到2):
45°00''00"
倒角:
225°3''20.61"
正向和反向方位角的答案都是45度，但反向则需要加180度，即:180+ 45 = 225度.
我不了解逻辑，是添加到180/360还是从180/360减去.
注意:我知道给定东，北的逻辑，但不了解纬度和经度.
Hello all,
If someone knows about deciding the bearing direction, given latitude and longitude, that would be helpful. I don''t quite get the logic.
here''s an example.
Point 1:
Latitude: 41°15''18.000000"N
Longitude: 76°00''0.000000"W
Point 2:
Latitude:41°19''7.097720"N
Longitude: 75°54''55.972300"W
The calculated forward and reverse angles/Azimuth are :
Forward angle(from point 1 to 2):
45°00''00"
Reverse angle:
225°3''20.61"
The answer obtained for both forward and reverse azimuth is 45 degrees but for reverse I need to add 180 deg ie: 180+ 45 = 225 deg.
I don''t understand the logic, whether to add to 180/360 or subtract from 180/360.
Note: I know the logic given eastings and northings but not the latitude and longitude.
