International Date Line Longitude, Latitude Coordinates
I’ve been working on an update to Catfood Earth. Several people have asked me to draw the International Date Line on the time zones layer but I’ve struggled to find a decent source for the coordinates of the line segments. I finally ended up manually digitizing the version of the line that appears on Wikipedia. The original is licensed as Creative Commons Attribution-Share Alike 3.0 Unported so I’m making the coordinates below available under the same license:
| Longitude | Latitude |
|---|---|
| 180.0000 | 90.0000 |
| 180.0000 | 75.0000 |
| -169.2500 | 67.7356 |
| -169.2500 | 65.0189 |
| 170.0500 | 52.6863 |
| 180.0000 | 47.8353 |
| 180.0000 | -0.9000 |
| -159.6500 | -0.9000 |
| -159.6500 | 2.9000 |
| -161.8500 | 2.9000 |
| -161.8500 | 5.0000 |
| -155.9500 | 5.0000 |
| -150.6500 | -7.8000 |
| -150.6500 | -10.0000 |
| -156.0500 | -10.0000 |
| -156.0500 | -7.8000 |
| -178.0500 | -7.80000 |
| -172.7500 | -15.0000 |
| -172.7500 | -45.0000 |
| 180.0000 | -51.1815 |
| 180.0000 | -90.0000 |
This looks great for Catfood Earth. Please take the coordinates with a pinch of salt if you’re designing a cruise missile guidance system or something.
