Lon Lat Lon Lat
Lat&#x2F;Lon is really the standard. The fact that some software internally represents it as Lon&#x2F;Lat doesn&#x27;t mean it&#x27;s not a settled issue. If you look up the coordinate of a location - it&#x27;s always in Lat&#x2F;Long. You can&#x27;t rewrite all the books and change all the maps to make it nicer for programmers<p>As the linked post says, Lon&#x2F;Lat is generally easier to deal with b&#x2F;c it matches to X&#x2F;Y (and the North&#x2F;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<p>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&#x2F;Lat doesn&#x27;t fix everything.<p>What I personally lean towards now is converting everything on read-in to a South&#x2F;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&#x2F;libraries I can&#x27;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.<p>That all said, I&#x27;m a total noob and I have no &quot;geospatial&quot; background (just writing some software to deal with rain data right now) So this isn&#x27;t pro advice.  I&#x27;d just be curious what others think
