As the linked post says, Lon/Lat is generally easier to deal with b/c it matches to X/Y (and the North/Up way we look at maps). But you still have annoyances. For instance Lon goes 0-360 but Lat goes -90 to 90. This is also mathematically inconvenient
Add on top of that the X-Y coordinate on images generally have the X flipped and starting at the top left corner. So changing to Lon/Lat doesn't fix everything.
What I personally lean towards now is converting everything on read-in to a South/East coordinate system so it matches the flipped X-Y of images (like GeoTIFFs) and just always working in that system. Image manipulation, drawing to screen, output etc. - those systems/libraries I can't really modify myself. Everything else I can manipulate in whatever coordinate system I want. So it makes sense to choose the most convenient. Plus only dealing with positive coordinates is a big plus.
That all said, I'm a total noob and I have no "geospatial" background (just writing some software to deal with rain data right now) So this isn't pro advice. I'd just be curious what others think
Sure Lat/Lon is the common presentation format for this particular coordinate system.
Right now in Sweden the time is 10:41 (it would be great if it was a couple of hours later, then I could say it's 14:41 to demonstrate the 24 hour time format). Yet, in software, I would represent that as time in UTC. Only when presenting to the user would I convert that to the users time zone.
My last name contain the letter "ö". In software, I would use an unicode string internally, then when writing out I would encoded that to utf-8. (20 years ago, I would have used an old character encoding called ISO/IEC 8859-1 or something like that, but you get my point).
For some damn reason I till don't understand, the decimal separator in Sweden is the comma and not the period. Still I would represent numbers internally as an integer or maybe float, and then when printing to to the user would I convert that to "123,4" (123.4) or something like that.
In Sweden, WGS84 is not the only common coordinate system. There are many others: SWEREF and SWEREF TM for example. Yes internally, depending on usecase, I would probably use a representation of WGS84 as reference, then convert that to present to the user...
This is how I think about coordinates.
I am ashamed how my country handled this pandemic and I'm ashamed that my fellow citizens are more interested in managing the public image of Sweden rather than learning from obvious mistakes.
I am therefore thankful that Nature published this. It has been debated since early 2020, but the narrative of Swedish exceptionalism is so strong, especially on the Internet, that I wouldn't be surprised if this will tried to be burried.
I have lost friends due to this, not because people have died of Covid but because foreign nationals, who moved to Sweden to work on some of the famous tech companies, have realized how poorly Sweden handled the pandemic. They have now moved to other countries instead.
