mercator

If your data are in map coordinates, then definitely do not use Web Mercator unless your map coordinates are also Web Mercator.

Having done both Spherical Mercator and Universal Transverse Mercator in my own code, UTM is something like 25 times as many arithmetic operations as Spherical.

Instead of looking at various original maps with region-specific projections, now the viewer is getting more and more exposure to just Mercator maps.

My understanding was that the complaint was when Mercator is used for wall maps like in the classroom.

There is massive distortion between the sizes of the US and Africa on a Mercator map.

So on small scale web-mercator isn't harmful for me, but most other projections wouldn't be either.

This is very easy to check if you have a globe and a Mercator map.

Mercator is often used today with online maps because people (especially journalists) just love Google Maps (which uses Web Mercator by default) and seem incapable of learning about alternatives or just map projections.

The West Wing did a really good clip on what's wrong with the Mercator Projection.

Web Mercator is not conformal, which is admitted in the last part of the document.

The transition into Mercator is pretty jarring at high latitudes (try zooming into Greenland).

The simpler calculation was probably chosen because it would be a bad idea to store or analyze data in Web Mercator (so the projection is done each time a tile is rendered).

"It starts with a lie" Web Mercator is a Mercator projection, so it's not a lie, just slightly imprecise.

What is Cambodia?" To answer these questions web-mercator is nearly the worst projection possible.

"which is admitted in the very end of the post" The post discusses Web Mercator in the second sentence.

"The most obvious reason to use web-mercator is it is easily computed." Which the article discusses.

Mercator has many very useful properties, such as local conformality which is why Google Maps and other maps providers use it.

That is the first over-two-thirds of the article, which is an argument for Mercator.

Note that Redis Geo uses the infamous Web Mercator, used also by Microsoft Maps, Google Maps, OpenStreeMap, MapQuest, etc.
