Pretty much a true reflection apart from the earth not actually being a perfect sphere ,roughly, it's slightly wider round the equator than is is circumnavigating the world pole to pole. Essentially though it is a true reflection 2 Link to comment Share on other sites More sharing options...

I'll help you. "As close to correct projection as possible". If you need that further explain let me know. But I know you don't, as you understood well what I asked for. As people have said, no map projection is more 'correct' than any other. It just depends what you're trying to show. If you get the sizes right, the shapes will be all wrong. And vice versa. Only a globe can show things (roughly) 'as they are'. Edited October 10, 2019 by mjmooney 3 Link to comment Share on other sites More sharing options...

bickster Posted October 10, 2019 Moderator Share Posted October 10, 2019 How maps can be misleading. The flat Map is the current Presidential Approval / dissaproval in each county in the USA but then it changes to th map adjusted to population. Red approves of Trum, Blue doesn't 3 Link to comment Share on other sites More sharing options...

And you're right, not even complex 3D models are totally accurate or correct. There are various Geodetic models that are used in navigation - e.g. GNSS/GPS etc. Some are more accurate for Europe (the Western military tends to use WGS84 though, others are more accurate for other parts of the Globe - ED50, for example). I mean they're all astonishingly good, all things considered, but none are perfect and they get updated from time to time - the WGS84 geodetic model was updated about 15 years ago, because the earth and its topography changes - islands form, mountains sink, coasts are eroded...etc. Plus satellite technology gives ever better definition and accuracy of heights and so on.

sharkyvilla Posted October 10, 2019 Share Posted October 10, 2019 So what do the flat earth society use for maps of the world? I'm asking here because I dont know how else I'd find the answer on the internet. Link to comment Share on other sites More sharing options...

wilko154 Posted October 11, 2019 Share Posted October 11, 2019 I guess the 3D vs 2D is why the Mercator Projection is a thing (whether it's true or not is another debate) 1 Link to comment Share on other sites More sharing options...

But look at how much Greenland, North America and Russia 'shrink', compared to South America, Africa and Australia. EDIT: Or have I got it the wrong way round vis a vis dark blue and light blue?

No you are correct, the dark blue is the shrinkage. It's to do with the longitude and latitude. Although neither maps are going to be anywhere near perfectly reliable spec. 1 Link to comment Share on other sites More sharing options...
chrisp65 Posted October 12, 2019 Share Posted October 12, 2019 Loads of map based schizz in Waterstones, wall maps, globes, jigsaws. I could have made the collection bigger but my missus was watching me from over by the bdsm section. 2 Link to comment Share on other sites More sharing options...
