Really, I think that people have cause and effect backwards. If you're interested in foreign countries, then you're probably going to be looking at maps to understand where those countries are in relation to each other, and then you'll develop a sense for what makes a good map projection. If you do...

I was just about finally to post a mention of this, having seen it a few days ago. The campaign to replace Mercator with an equal-area projection has been around for a long time, before the infamous Peters projection came along. The Equal Earth projection is at least passable. I suppose it is felt t...

...for a map with South at the top.

is an URL on the IBGE site for this Brazilian map that's made the news.

That link still doesn't work. Did you mean to post http://www.quadibloc.com/maps/images/conhem2.gif?

Oops, yes, that definitely is the diagram I wanted to point you to. But the other link, to the page, should have worked.

I am highly impressed by the Liquid Earth projection, as it is beautiful in appearance, showing the continents with very little distortion. Doing that, and also having the projection approximately equal-area is quite an achievement. I don't know enough about how to work with meshes to do anything li...

I am red-faced now! Because all the atlas maps in the Monarch World Atlas, except for one of Canada on a conic projection, were on the Mercator projection, I had simply assumed, all the way from childhood, that the world map was also on the Mercator projection. But just now, as I was taking a closer...

How are the domes over Eurasia arranged? You can tell from the curvature of the meridians that the map won't work if you simpe glue the left edge to the right edge like you can for the cylindrical portion. Yes, you're right. On the left of the map, the dome has 100 degrees East longitude as its sta...

The Van der Grinten III projection is the one where the parallels are horizontal lines, at the positions the parallels of the original Van der Grinten projection intersect the central meridian. I have noted on my web page that the Van der Grinten projection, along with the Van der Grinten IV project...

If you can replace the Chinese government with a more benevolent one that's still ethnically Chinese, then you can do that with Russia, too. Unless you believe that Russians are all genetically-inferior subhumans who need to be rounded into concentration camps and gassed. Also, the United States ar...

If I were dictator of the world, I'd go for a global phase-out of fossil fuels to stop Siberia's land and resources making Russia a great power. This might have other benefits too. Taking Siberia away from Russia would just set the stage for a Russian war of reconquest. Oh, indeed, fossil fuels mus...
