Black Panther is a huge Hollywood hit set in the fictional country of Wakanda. The lead character has been through many iterations since his first appearance in Marvel Comics in 1966, as has his country. Wakanda is the most scientifically advanced country in the world. Isolation has enabled it to resist colonization and to develop its own independent technology. 

The first map, from Jungle Action Volume 2 #6, shows the Atlantic Ocean in the lower left placing Wakanda near the west coast of Africa.
A couple of episodes later the map was re-presented "with new details." The Atlantic Ocean was removed, probably to place Wakanda more in East Africa. Killmonger's Village is no longer a coastal settlement. There is an arrow in the bottom left of the map pointing to the Indian Ocean. There is speculation that they "flipped" the map (south is now up).
This became the definitive version of the map for decades. In 2008, Marvel published its Atlas of Fantastic Places giving a precise location of Wakanda and neighbors between Ethiopia and Kenya.
In 2016, a new version of the comic was written by Ta-Nehisi Coates. He drew a couple of new iterations of the map placing it on the western shore of Lake Victoria.
The map above was created in Photoshop. Coates discusses his process in this article from The Atlantic. A later, more detailed version was done by Coates and Manny Mederos.
In the recent movie Captain America: Civil War, Wakanda appears to the northwest of Uganda, close to the location from Marvel's atlas. Here is a screenshot via comicbook.com
The current movie has it slightly to the southwest of the Coates map bordering on Rwanda's Lake Kivu. The image below is from Marvel's Black Panther: The Art of the Movie

Where will it move next?

Batman co-creator Bill Finger first named Gotham in 1940 for Batman #4. However, the city was not mapped until 1998, when a plot involving a catastrophic earthquake required a map. Artist and illustrator Elliot R. Brown was hired for the task.
The city has always had a resemblance to New York but, according to Finger "We didn’t call it New York because we wanted anybody in any city to identify with it." With no formal training in cartography, Brown was tasked with creating a city that had all the necessary diverse elements.

"The DC Comics editors made it clear that Gotham City was an idealized version of Manhattan. Like most comic book constructs, it had to do a lot of things. It needed sophistication and a seamy side. A business district and fine residences. Entertainment, meat packing, garment district, docks and their dockside business. In short all of Manhattan and Brooklyn stuffed into a … well, a nice page layout." - Brown

Early sketches of his map can be seen on his website, including this one.
The city needed to be an island so that federal agents could seal it off from the mainland by dynamiting the bridges and tunnels. In addition to the New York elements, he also added some "Chicago-like" bridges in the middle of town, to "add some story potential."

Here is one version of the final product as it appeared in the comics circa 1999, via Smithsonian.
So where is Gotham City? It is often considered to be on the east coast of the United States but it's an open question due to some contradictory descriptions of it's location. From io9's Is Gotham City Really in New Jersey?

Gotham also has been hit by earthquakes (1999's No Man's Land...), sits in the Central Time Zone (Man-Bat #3), and was a cowboy town in the 1800s (2011's All-Star Western).

The Batman wikia has a modified google map placing Gotham in Great Bay, just north of Brigantine (and Atlantic City), New Jersey.
The io9 page shows this image from a 1978 comic also placing Gotham in South Jersey but on the Delaware Bay, across from Metropolis (Metropolis, Delaware?)

That's a lot of action for an area mainly populated by horseshoe crabs.

xkcd, everyone's favorite nerdy webcomic recently featured the United Shapes of America.


According to the author:

It's a hand-drawn map I made of the United States, with every state replaced by something I've always thought the state was shaped like like. (Florida is an eggplant, of course, what else would it be?)

 You can see a larger version here. Some of the more creative ones are Montana as half of a muffin, Vermont as an upside down microscope, Tennessee as a stack of books and Illinois as an upside down gangster. I'm still trying to decide if the Georgia-Missouri switch is clever or just a cop out. Judge for yourself.

xkcd, everyone's favorite nerdy webcomic takes on map projections this week. I'll be the first to admit that I've never heard of the Waterman Butterfly or the Peirce Quincuncial. And I call myself a cartographer!

I've looked at this site many times and still don't completely get it. It's an interactive promotion for Chris Ware's graphic novel Jimmy Corrigan: The Smartest Boy on Earth. I have not read it, but the story here does not appear to follow the book as described online. It does make an interesting use of maps to tell a story. Click the map below and then the lower arrow. Next click on one of the circles on the globe and you get a piece of the story.

This a typical immigrant coming to the US to find whatever opportunities are out there story. If you really want to follow it the trick is to click on what's supposed to be Tennessee but really is too far south and east. Then click the right arrows. There seem to be parallel stories about slavery and some traffic accident in Panama. Again, the relationship to this graphic novel is unclear. Below is a typical sequence showing parts of the story.


If you click on Chicago you get this nice little zoom in sequence


The site does work in that it makes me curious to read the story. Then again after months of looking I have yet to actually place my order.

Ever wondered about the geography of Springfield? Not the one in Illinois, the one in the Simpsons of course. Here's your map.
