| Jun 3, 2022 at 16:21 | comment | added | HJA24 | @barrycarter yes, exactly. So I want to display it like the second image where north is longer located straight up | |
| Jun 3, 2022 at 15:36 | comment | added | Barry Carter | You want to display your coordinates on the first map image you provided? In other words, you want to rotate your coordinates so that north no longer points straight up? | |

If possible, I want to display the coordinates based on the trueNorth angle. I added two screenshots.

| Jun 3, 2022 at 9:36 | comment | added | Hans Erren | So what do you want to do with your coordinate list? | |
| Jun 3, 2022 at 9:31 | comment | added | Hans Erren | This north arrow is placed on an almost upside-down map of the golf course. It is useful on a map, and if you need to reproduce that same map using your coordinate list. | |

correct. Can you explain to me how the value of 166 for trueNorth is related/calculated?

| Jun 3, 2022 at 7:50 | comment | added | Hans Erren | I checked your coordinate list: these are spot on the green of San Antonio TX golf course, so there is no need to change the coordinates. Where do you want to use them for, as the green is well mapped in openstreetmap? openstreetmap.org/way/769381482 | |

I added the data format, it's a simple txt-file. I don't know proj4. I used the utm-module to transform the longlat coordinates to cartesian coordinates.
