Add 128 point image

edit

Could somebody please add the 128 point picture? https://upload.wikimedia.org/wikipedia/commons/2/2b/128_point_compass_rose.png --Backinstadiums (talk) 14:43, 20 June 2019 (UTC)Reply

Link to Welsh wiki version goes to a place in the states not the Welsh version of this article. Chocolateediter (talk) 17:48, 28 December 2020 (UTC)Reply

Is there a suitable target on cy.wikipedia for this link? Just plain Bill (talk) 19:12, 28 December 2020 (UTC)Reply

Hatnotes and redirects

edit

This article currently has a lot of hatnotes (northeast, northwest, southeast, southwest) that are neither at the top of the article nor at the top of the section these redirests point to (see WP:HAT). So they are not helpful when I type northeast into the search box. I propose redirecting these four to the corresponding disambiguation pages, which can then point to Points of the compass. (I see no reason to point to the section Designations, but I have no strong opinions on this.) Any thoughts? --ἀνυπόδητος (talk) 15:16, 28 April 2022 (UTC)Reply

Mistake in compass rose?

edit
 
32-point compass rose

Moved here from IP 24.177.76.119's edit to the article

There is some kind of mistake! For the description does not match the diagram! The N point is indicated by the number 1, not 0; and the NbE point is indicated by the number 2, not 1, etc. In fact, compare to table in section "128 compass directions" bellow to understand this mistake.

32-point compass rose with associated direction names and equivalent degrees from north
I agree with the complaint. Assigning 32 (i.e., 0) to NbW instead of N contradicts the article text (and general logic) in a bad way. I also don’t really see any advantage to labeling the degrees at intervals of 10. Accordingly, I have just drafted this potential replacement. Feedback is highly welcome. jameslucas ▄▄▄ ▄ ▄▄▄ ▄▄▄ ▄ 21:46, 11 May 2022 (UTC)Reply
After coming back with fresh eyes and making some fixes and improvements, I got it to a place where I felt comfortable taking it live. I swapped the image in the article, but I’m still open to bug reports or suggestions. Cheers! jameslucas ▄▄▄ ▄ ▄▄▄ ▄▄▄ ▄ 17:27, 12 May 2022 (UTC)Reply
I also have some nice files on this subject, but don't see how I can attache it here.
Perhaps, this can help. Reference to them in two books:

Those might be difficult for me to access or understand. Is it possible for you summarize any unique attributes or insights they offer? Cheers! jameslucas ▄▄▄ ▄ ▄▄▄ ▄▄▄ ▄ 10:42, 27 May 2022 (UTC)Reply
something like this (with explanations) https://www.google.com/imgres?imgurl=https%3A%2F%2Fpics.livejournal.com%2Fnavigatorpirate%2Fpic%2F00244w49&imgrefurl=https%3A%2F%2Fnavigatorpirate.livejournal.com%2F295680.html&tbnid=xd_z6drHmex0HM&vet=12ahUKEwi3lbLm0YD4AhUTwikDHTD8AMcQMyhhegUIARCjAQ..i&docid=V4hD_bCOglInqM&w=600&h=593&q=%D1%80%D1%83%D0%BC%D0%B1&client=ubuntu&ved=2ahUKEwi3lbLm0YD4AhUTwikDHTD8AMcQMyhhegUIARCjAQ 24.177.76.119 (talk) 21:39, 27 May 2022 (UTC)Reply
Thank you for sharing. There is certainly a beauty to that compass rose, but unfortunately I do not understand the benefit to the complex numbering system (0, 1, 2, 3, 4, 5, 6, 7, 8, 7, 6, 5, 4, 3, 2, 1, 0, 1, 2, … ). Do those integers have some practical purpose? Numbering 0–31 may not have extensive application, but if nothing else it makes it easy to tell that there are 32 points. jameslucas ▄▄▄ ▄ ▄▄▄ ▄▄▄ ▄ 21:59, 30 May 2022 (UTC)Reply
Using Google I translated just part of explanation:
"With the development of navigation accuracy, each quarter of the horizon was divided into 90 directions. The main points N and S were marked 0°, and the points W and E—90°. The name of the quarters and the principle of counting directions remained the same. This staking system was called the quarter. Directions were indicated by the name of the quarter and the number of degrees, for example: NE 35 °, NW 47 °, SW 22 °.
The cards of modern compasses are still divided into 360 °, but a circular counting system is used, without distinction of quarters. In this system, the main points are marked as follows: N - 0 ° (360 °), E - 90 °, S - 180 ° and W - 270 °.
The circular counting system is simpler and clearer. However, the solution of most problems in navigation often forces navigators to use other systems. To do this, the directions given in one system are translated into directions according to another system, especially from circular to quarter and vice versa."
"In the rhumb system, directions are counted in rhumbs along the quarters of the horizon from points N and S towards E or W. In this case, the rhumbs have the corresponding names in the order of numbers from 0 to 8 in each quarter.
Rumba N and S are called main, or zero, because from them all rhumbs are counted. Rumba E and W are also called the main points and they end with the number of points in each quarter.
Half rumba of each quarter called quarters. They divide the quarters in half and are designated by the initial letters of the main points between which they are located: NE, SE, SW, NW. By the name of these points, the quarters of the horizon plane are also called."
If you wish, you can translate more. I suggest those sites:

This is interesting and probably deserves mentioning in the article. I’ll noodle around a variant of the image using this system next time I have a spare moment at my desk. One quick question: can you tell if this counting system is specific to a language or region? jameslucas ▄▄▄ ▄ ▄▄▄ ▄▄▄ ▄ 13:24, 1 June 2022 (UTC)Reply
I don't think this "system is specific to a language or region". Navigation was universal science or school. However I can't speak for all "systems". Just keep in mind, what in many books, they used until late 1980s, they named O(Ost in German or Oost in Netherlands) instead of E(East in English). Which is also proves it was universal. 24.177.76.119 (talk) 17:51, 1 June 2022 (UTC)Reply
couple more Google Translates:
"Semicircular system of counting directions. In this system, directions are counted from the main points N or S towards east E or west W from 0 ° to 180 °, writing as N 120 E or S 120 E or S 60 E or S 60 W."
"There are four reference systems for directions in the sea. Rumbovaya, currently used to determine the direction of wind and current. Quarter - currently used in nautical astronomy. Semicircular - also used in nautical astronomy. Circular - is currently used everywhere." 24.177.76.119 (talk) 18:02, 1 June 2022 (UTC)Reply

First sentence

edit

I removed "vector" from the first sentence. It linked to Euclidean vectors, which have both magnitude (or distance) and direction; compass points have only direction. IMO there is enough context nearby to establish which sense of "direction" is being used. Just plain Bill (talk) 19:33, 12 May 2022 (UTC)Reply

@Just plain Bill: Good point about the magnitude—that’s a deal breaker all right. And while I didn’t find the context surrounding ‘direction’ as it existed yesterday sufficient to unambiguously suggest a particular use, your latest draft is totally doing the trick for me. Nice work! jameslucas ▄▄▄ ▄ ▄▄▄ ▄▄▄ ▄ 20:24, 12 May 2022 (UTC)Reply
