THANK YOU! After reading several confusing blogs, articles, etc., this was exactly what I was looking for! Now wish me luck when I talk to my neighbor 😉
It should be written with like a dry erase marker or penciled in on a separate navigation log sheet next to a map waypoint; reverse azimuth, time frame of arrival, then the bearing adjustment shown in the video from that waypoint.
It would be helpful to have an appended photo of the quadrant/bearing diagram that we could photocopy onto a plastic sheet and stick on our Bruntons. I have a Brunton that reads in degrees, but would prefer one that reads in quadrants. I want to make an easy graphical overlay. When considering bedding attitudes, N45E is the same as S45W. It's the same planer feature. The dip direction is very important to understanding the feature. N45E, 15SE is an example of a common quadrant with a dip. Instead of Due East, I write N90E. As a geologist, we are generally trying to represent a planer feature, like a bedding plane or joint on a 2D map. It seems to me, that writing that a bed has a strike of S225 is not the correct way to describe it. It would be better to say that it is N45E (same as N45) and then give the dip direction and angle. The strike is a line that would have the same elevation at both ends, therefore it is not pointing to either the NE or the SW. It's level. As that is the case, why use bearing degrees unless you are referring to the plunge of a feature?
That's great! You should check out my videos on what I wish I had known going into Geology as a field of study/careeer: ru-vid.com/group/PL-vzyMUHq3BZNYowtBWndf382nEblSm4o
Looking for some confirmation. Long ago I read that you take a bearing with the quadrant system and you take a heading using the azimuth system. Have you ever come across this?
So in your conversion from bearing to azimuth you only use even degrees, how about bearings that read S 46 degrees 11 minutes and 59 seconds how would those convert to an azimuth?
Great question! You would essentially convert the minutes and seconds to decimals. Here is a great video on how to do that: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6ovyeRepSQk.html
Blaney Services, Sec. divided by 60 = ? Then take the result and add what the min. Is and divide that by 60 = ? Then add the result to the degree = ? Then revert back to the quadrant diagram he drew, if it’s between 360 and 90 it stays the same, if it’s between 90 and 180 then subtract 180. If it’s between 180 and 270 then add 180, if it’s between270 and 360 then subtract 360. Example: N49 50’ 29”w 29/60= 0.4833 0.4833 + 50 = 50.4833 50.833/60= 0.8413 Since the degree is in the quadrant between 270 and 360 we would subtract 360. Azimuth is 359.1586 Hope this helps.
As an astronomer azimuth has always been a simple thing, easy to understand. As a hill walker, a bearing also is easy to understand, it's even the same as my marina mates. So who thought this definition of "bearing" was better? It's a mind-cluster fuck right up there with old money and imperial weights and measures. I can't even begin to think why surveyors think N25W is a useful term?
Hello sir! Can I have a question can you answer this into quadrant notation and azimuthal notation? I'm a bit confuse on my class This are the questions Turn this into azimuthal notation 1.) N60W 2.) S20E 3.) N15E Turn this into quadrant notation 1.)75 degree 2.)355 degree 3.)100 degree Sorry I wasn't able to make degree sign 🙁 But can you please help me on this question? Thanks if you answer it
