Are these ratios of hours online in a day (3:11 implies 3 out of 11 hours) online per day? That seems unlikely given how difficult comparisons like that would be to make.

That leaves the other option that these “hours” are actually hours and minutes (hours:minutes). But, that option is almost as bad simply because then the map subtitle has lied to us through omission in not mentioning minutes.

This map should have either just shown the number of total minutes or shown the hours in decimal rounded to a sane number of significant digits. Making a distinction of a minute or three amongst such broadly general averages of almost certainly guesstimated numbers self reported in a survey seems a poor choice.

It’s a misleading legend, but the note at the bottom tries to clear it up a bit. This map seems to more be like “We took the range maps of 238 species of fish and overlaid them. The red area is where practically all of those range maps of each 238 species of fish overlapped.” Of course there are other fish, but they were not included here because the map maker didn’t have the right kind of dataset for them. To me that seems to indicate that this map isn’t so much a map of actual biodiversity measured, but the potential for biodiversity of the region. Given that it’s fish, I guess we shouldn’t be surprised that this area is somewhere between/near the northern continent’s biggest river, a large gulf, and ancient mountain range, and a coast with a strong warm current (for now…).

Rude.

Bro, if you didn’t want people to respond with genuine takes on what you post and if you’re going to be so defensive, why are you even here?

Also, I’m not defending anything. DST should be the standard time because we spend most of the year in it anyway. But that’s just my own opinion, which I feel no need to defend to you or anyone else.

You’re so wound up about making your point and defending your point of view that you’re not actually comprehending my comments. It’s your map in the sense that you are presenting it to us, who authored it isn’t really relevant to this discussion.

Just pointing out the ridiculousness of getting petty and insulting about the way other people define time scales because you don’t agree. There is no objective truth here, just subjective opinions. ALL of those opinions and methods have flaws, especially your beloved “everyone should just use UTC”. There is no such thing as “correct” here, so putting that word in your map’s title and using “right” and “wrong” in this discussion is just naive.

We spend most of our year in daylight savings time. Standard time is the pretendy-magic-time.

This map really brings home how awful this projection is for this map’s purpose and how awful most projections really are near the poles. Greenland isn’t that big. I know this map is Plate Carree, not Mercator, but the size issue of an equirectangular projection is really similar when comparing longitude and size for the entire globe from pole to equator. 15 degrees of longitude for a timezone stops making sense that close to the poles. Greenland would mostly fit in the central time zone of the United States for example. Given its sparse population, dividing it up into 3 timezones seems unnecessary.

Strawman arguments aside, it seems you’ve already forgotten how this comment chain started. Just let it go.

This is a map enthusiast community, not a lying with statistics and graphic design community.

It says “not to scale”, which in the world of mapping means very specifically that the scale is inconsistent. An exaggerated vertical scale would not include the disclaimer for “not to scale” and is very common, as I already said. It’s common for maps showing vertical reliefs like profiles or cross sections to have a horizontal scale of something like 1:20 while the vertical dimension has a scale of 1:5 or 1:10, which would still be considered “to scale”. If you still can’t fit everything on a single sheet, you can add a break line or a jog to indicate a discontinuity, but the map would still be “to scale”. This map is “not to scale” because it says so, so the only real information we should be able to glean from it are the connections between things; size, angles, and lengths as are meaningless because that’s what “not to scale” is specifically warning us about.

I didn’t break out the ruler or anything, just going off of the pixelated disclaimer at the bottom.

Why bother making this at all if it’s not to scale? Sure, nobody expects the horizontal scale to be the same as the vertical scale. Vertical exaggeration is common when displaying profiles or cross sections, but those are generally still considered to be at a particular scale. But, if the vertical scale isn’t consistent, then what even is the point of the graphic? Just list some numbers in a table. Putting this in graphical form without a consistent scale is just lying and lazy.
