Worldwide Urbanization

In 2015 The Guardian posted a couple of interesting maps highlighting the trends of urbanization. By 2050 the world population is expected to be 70% urbanized. Here is a map showing how many people are added each hour to the world's large cities.
The data is from the London School of Economics Urban Age program. The map is a bit hard to read. Numbers are sized by city growth, making lower growth cities like London hard to read. Since the dots are already sized by number they could have kept the numbers all at a readable size. Also using a different color for each continent is somewhat pointless. Nevertheless the data is interesting-Lagos gains 85 new residents every hour while Rio only gains 10.
The map below shows past and projected growth by time period.
Green cities saw most of their growth occur by 1950 while the more yellow ones are currently seeing the most growth. Some cities, particularly in India have a more mixed pattern of concentric circles showing steady growth throughout past and future decades. These maps are a bit hard to read at this size. If you click on them, you can see larger sizes. Here is a detail from the map above showing Europe vs South Asia and East Africa.

Fifty Fantasy States

Chris Engelsma is working on creating fantasy maps for the 50 states using toponyms - translations of place names to their original meanings. Here is North Dakota , aka Northern Land of Friends.
Here is a nice detail from Idaho (Light on the Mountains) showing the light on the mountains
10 states are completed. Prints are available on his Etsy page. This also includes his map of Australia.

San Francisco Ships Update

Last December I posted some maps showing the ships that are buried under San Francisco. As a quick recap, what is now the Financial District was once a shallow cove. During the gold rush many ships landed here and were quickly abandoned or sunk. The cove was eventually filled with these ships still in place.
The San Francisco Maritime National Historical Park is working on a new map of these ships, adding details from archaeologists that were not on their original map from 1963.
This map will appear in the Park's visitor center. Here is a detail from the image-via National Geographic
A detail of the detail just to show how nice it looks up close.

Here is part of the museum's original 1963 map - also via National Geographic

The Evolution of Ordnance Survey Mapping

Britain's Ordnance Survey has consistently produced some of the world's finest and most detailed maps. Here is a display showing the evolution of their mapping styles, blended together with Photoshop.
I like the subtle stylings of 1895. You're welcome to disagree. I also really like how the legend is made from a theoretical landscape.

Beyond the Sea

Our local Bostonographer and Maptime Boston co-host Andy Woodruff has been working for a while on mapping what is across the ocean from where you stand. His latest "flowing and exploding" version is quite fun to watch,
or interact with by pointing your mouse and seeing where it goes-here.
If the results are unexpected it is because the lines go perpendicular to the coastline, rather than following a specific latitude. We are conditioned to think that "across" means the same latitude on the other side. As children going to the Jersey shore we imagined that we were looking at Portugal on the horizon-because we were geography nerds. However the shore is angled in a northeasterly direction so you are actually looking southeast, towards either South Africa or in some areas missing that continent entirely and rounding the Cape of Good Hope, reaching all the way to the west coast of Australia. That would be the case for most of the shoreline, but any bay or other odd turn in the coast and you may be looking at Norway, Nova Scotia, Morocco or Brazil.

If you are more interested in latitude, there is a nice map series from the Washington Post, showing the continents color coded by what's across the way. Here is Africa, for example.
 This one shows that Portugal is across from the Jersey shore but to see it you need to look at an angle.

Maps of the Flat Earth Society

In a world of alternate facts and ridiculous theories, the flat earth alternate fact has stood the test of time despite obvious evidence to the contrary. All NBA star and flat-earther Kyrie Irving needs to do is look out the plane window on his next flight to see the curvature of the earth. He doesn't even need to pay attention to the northward tilt of the flight path.

The Flat Earth Society has various examples of flat-earth maps such as this one by Samuel Rowbotham.
It has a nice letter coding system to help the average flat earther figure out the difference between Land (L) and Water (W). N is the north pole (more on that below) and D is...darkness?

One of the most common maps used by flat earthers is from Wilbur Glenn Voliva, an evangelist who offered a $5,000 prize for anyone who could disprove the earth is flat. By choosing to disbelieve any takers, he never had to pay the money.
What these maps have in common is that they all see the world as round-circular or elliptical. The Sun (as shown above) rotates around the equator, explaining the differences in climate. They believe in the North Pole, but not in the South Pole. The southern edges of the world are conveniently edged by a wall of ice to keep mariners from falling off. Some believe in a dome shaped sky with stars hanging down.

The belief that the South Pole cannot exist, gives rise to many conspiracy theories about why airline flight routes go the way they do. These theories are easily debunked by anyone who has flown between cities in the southern hemisphere.

Yes they don't fly over the South pole because the great circle routes are much further north.

Here is a flat earth globe

The Rapid Growth of Chinese Metro Systems

This remarkable animation from Peter Dovak shows the rapidly accelerating growth of metro systems in China, including Taiwan.
China's first metro opened in Beijing in 1969. Growth of the systems was modest up to 1990. From then until (proposed) 2020 you can see how quickly things changed. The animation is an adaptation from his wonderful mini metros project where he designed a bunch of icons for wordlwide metro systems, many of them instantly recognizable, such as Washington DC (bottom) - Beijing is the one below.

English Settlement

 The English Landscape and Identities Project has some tri-variate maps of England showing eras of archaeological sites. The author, Chris Green, begins with an apology to those with color deficiencies. Because three color channels are needed, it would be hard to make this more legible to color blind readers*. The legend is shown first to see what you are looking at.
Darker areas are more "complex" - meaning there are sites from more time periods. The primary colors show more specific time periods as seen above. Magenta is Roman in case the image is hard to read.
There is a second map based on more local variation on the blog post, but I find this one easier to interpret. Some of the patterns that show up are settlement along Roman roads (magenta lines), some clusters of prehistoric sites in the southwest and northeast and a much lower level of intensity in the west (fewer archaeological sites here?) Some of the darkest, most intense areas are along major river valleys where quarrying activities have possibly uncovered more sites than average.

This map is based on available data and may not tell the full story but it does give an idea of the variation and complexity of archaeological records.

* This color scheme (via StackExchange) would have worked for color deficiencies.

Seattle Awareness Map

In 1978 the Seattle Department of Community Development published this map to raise awareness of the city's cultural landmarks.
Seattle Municipal Archives posted a scanned copy on their Flickr site. The cover is a nice grouping of buildings, statues and ferries.
Inside the map is densely populated with landmarks and yellow descriptive text bubbles,
sometimes with additional info or commentary added.
 Some more detailed scans can be found on Rob Ketcherside's Flickr pages.
One final view-because I briefly lived near the Arboretum Gate House

LEGO Poland

Last year, the first LEGO store in Poland opened, in a Warsaw shopping mall. The event was celebrated with a huge 3D model of the country built by kids and adults.
Here are some photos from various stages of completion via this Flickr gallery.

Follow the Advancing Japanese Empire

In 1942 this map was published in Japan for children so they could follow the progress of the imperial forces during World War II.
Japan, occupied and allied countries are shown in bright red. The map is full of caricatures of the natural resources of each area. Bold red arrows show the hoped direction of conquest.
Here are some details from northern Africa and southern Europe.

The map, titled "From the East, from the West" was produced at the high point of Japan's war effort for a children's publication.

Mexico City's Shaky Laky Foundation

Mexico City, one of the world's largest urban areas is built on a lake. The Aztecs built what was Tenochtitlán on an island in Lake Texcoco, connected by causeways to the mainland.
When the Spanish arrived they decided to expand the city by draining the lake. They did not manage the water properly as the Aztecs had done. Draining and pumping water from underground has caused the city to sink. This in turn has caused very frequent flooding and also ironically made water scarce.

I was curious to see what areas of the modern day city sit on top of the ancient lake beds but have not found a map on the web that makes this very clear. This circa 1519 map on Wikipedia shows some locations, but not the modern urban area.
I took the .svg version of this map through a complicated software process and georeferenced it as best I can with my limited knowledge of the area. Here are two versions of this map overlaid on two different base maps to give and idea of where the ancient lake was. The first is on a National Geographic map via ESRI.
Keep in mind that the location of the lake is based on my best estimates. To avoid the assumption of higher level accuracy, I did not make a zoomed in version.
Here is another version using CARTO for the background. Each map has its advantages and disadvantages for legibility. On the one below, you can see the subway network which is kind of cool.
There are some interesting ideas of how such a large city can cope with the ecological and public health problems it faces including an ambitious proposal for a 145 million square mile Lake Texcoco Ecological Park - 23 times the size of the city's huge Chapultepec Park. Clicking the numbers on the map below, you can see some of the proposed projects.  
The Texcoco Lake Ecological Park will become a tangible symbol of how our society can enter as an integral part into natural processes and help the proper functioning of the landscape.

Lake Texcoco Park is a work in progress, a vision of a remarkable place conceived by a collaborative group of scientists, engineers, biologists, chemists, ecologists, architects, urban planners, landscapers, and politicians.
