Meander Maps for Imaginary Rivers

Robert Hodgin Meander Maps

Robert Hodgin Meander Maps

Robert Hodgin Meander Maps

I have written previously about cartographer Harold Fisk’s wonderful meander maps of the Mississippi River produced for the Army Corps of Engineers. Borrowing the aesthetic of these maps, interactive artist & engineer Robert Hodgin wrote some software called Meander to generate meander maps for fictional rivers.

From an input curve, the terrain, land plots, side roads, highways, marsh land and mountain peaks are generated and prominent features are named. The map is then weathered and rendered in the style of old US Army Corp of Engineers maps from the 1930s and 40s.

You can check some of the generated maps out on Twitter or on Instagram, including some prototypes and animations (this one is my favorite). Hodgin has promised a full write-up of the project; I’ll link to it when he publishes it.

Coincidentally, while I was writing this post I got an email from a reader about an audiovisual installation called Meandering River that displayed “real-time visuals generated by an algorithm and music composed by an A.I.”

Synchronicity!

Update: Hodgin wrote about the Meander project on his website and included several more gorgeous examples of his output.


The United States of Voronoi

US Voronoi map

From Jason Davies, this is a US map where the state borders have been redrawn so that all points closest to a state capital than to any other form a state a la Voronoi diagrams. See also Voronoi maps of world airports and world capitals.

It’s interesting that many of the states’ new shapes are similar to their current ones, suggesting that the placement of the capitals relative to borders was somewhat naturally Voronoi-esque, like how people naturally space themselves in elevators or parks.


Colorful New Geological Map of the Moon

Moon Geological Map

Moon Geological Map

In collaboration with NASA and the Lunar and Planetary Institute, the USGS has released the first complete geological map of the Moon’s surface.

This new work represents a seamless, globally consistent, 1:5,000,000-scale geologic map derived from the six digitally renovated geologic maps (see Source Online Linkage below). The goal of this project was to create a digital resource for science research and analysis, future geologic mapping efforts, be it local-, regional-, or global-scale products, and as a resource for the educators and the public interested in lunar geology.

Strange Maps has more information on how the map came to be and what it shows.

The map was created by the U.S. Geological Service’s Astrogeology Science Center in Flagstaff, Arizona. In collaboration with NASA and the Lunar and Planetary Institute, it combined six ‘regional’ maps of the Moon made during the Apollo era (1961-1975) with input from more recent unmanned lunar missions.

This included data on the polar regions from NASA’s Lunar Orbiter Laser Altimeter (LOLA) and close-ups of the equatorial zone from the Japanese Space Agency’s recent SELENE mission.

The two images above show the entire map and a detailed view of a single area (which includes the landing sites of 3 Apollo missions) while the video shows a rotating globe version of the map.


Homemade Maps of People’s Limited Surroundings During the Pandemic

Covid Maps

Covid Maps

CityLab asked its readers to “draw maps of their worlds in the time of coronavirus”. They drew floor plans, neighborhood walking diagrams, and more abstract representations of their surroundings.

You charted how your homes, neighborhoods, cities and countries have transformed under social distancing and stay-at-home orders around the planet, from daily work routines and the routes of your “sanity walks,” to the people you miss and the places you fled.

While most used markers, pens, and computer-based drawing tools to sketch maps by hand, some used watercolors, clay, and photography. Some were humorous, others heart-wrenching - between them all, a full spectrum of quarantine-era emotion emerged.

Spinnable 3D Models of the British Library’s 16th Century Globes

The British Library has digitized some of their 17th & 18th century globes into 3D models that you can explore and spin online (and in VR). These are seriously cool at fullscreen.

During the so-called ‘Age of Exploration’, expanding European geographical and astronomical knowledge fuelled the demand for maps and sea charts. It also inspired experimentation in the art of globe-making, and the first half of the 16th century saw the production of several models, both hand-painted and printed.

Printing made it possible to produce globes in greater numbers at lower cost so they could be more widely distributed. The printed globe, terrestrial and celestial, soon became established as the standard type of globe, sometimes called the ‘common’ globe, and the methods of manufacture changed surprisingly little from the mid-16th century until the 20th century.

The one at the top of this post is my favorite: Willem Janszoon Blaeu’s Celestial Globe from 1602. (via @john_overholt)


Cellphone Data Shows How Quickly Partying Spring Breakers Spread Across the Country

People on Spring Break in Florida for the past couple of weeks were famously unconcerned with social distancing measures implementing in other areas of the country to help stem the tide of COVID-19 infections and save lives. Using cellphone location data from just the phones of the people gathered on a single beach in Fort Lauderdale, Florida, this video shows just how far those people spread across the country when they went home, possibly taking SARS-CoV-2 with them. They go everywhere.

Show of hands: who feels uncomfortable being reminded of the extent to which 3rd party companies know the location of our cellphones? With tools like the one demonstrated in the video & other easily available info, it has to be trivial to identify individuals by name using even “randomized” data and so-called metadata.

The Drawings Secretly Inserted into Official Swiss Topographical Maps

Hidden drawing in a Swiss map

Hidden drawing in a Swiss map

For decades, mapmakers working for the Swiss Federal Office of Topography have defied their mandates to create the most accurate maps possible by covertly inserting drawings in official maps.

But on certain maps, in Switzerland’s more remote regions, there is also, curiously, a spider, a man’s face, a naked woman, a hiker, a fish, and a marmot. These barely-perceptible apparitions aren’t mistakes, but rather illustrations hidden by the official cartographers at Swisstopo in defiance of their mandate “to reconstitute reality.” Maps published by Swisstopo undergo a rigorous proofreading process, so to find an illicit drawing means that the cartographer has outsmarted his colleagues.

It also implies that the mapmaker has openly violated his commitment to accuracy, risking professional repercussions on account of an alpine rodent. No cartographer has been fired over these drawings, but then again, most were only discovered once their author had already left. (Many mapmakers timed the publication of their drawing to coincide with their retirement.)

Some of these blend remarkably well within the usual details of the maps — I never would have noticed the reclining nude in the second image above if it weren’t highlighted.

Linguistic Constellations

Linguistic Constellations

Linguistic Constellations

Illustrator Jerry M. Wilson has drawn a series of constellations that explore the etymology of the constellations’ names and related words in several languages. So for example, “Taurus” is Latin for “bull”, which is “toro” in Spanish & Italian and “tyr” in Danish. And then you also have associated words like “toreador” (“bullfighter” in Spanish) and “teurastamo” (Finnish for “slaughterhouse”)…a constellation of words related to “Taurus”.


Cycling Through All the Streets of London

Over a period of four years, Davis Vilums cycled every street in central London. A map and a time lapse of his journeys:

London Cycle Map

Including some irregular times off, overall it took me four years to visit every single road on the map. When I started this hobby, it took me 30 to 40 minutes to do the route. Later it expanded to 2 hours to get to the office when I tried to reach the furthest places on my map. One of the main goals was never to be late for work. From the beginning, I planned to visit not only the main roads but every single accessible mews, yard, park trail, and a path that was possible to go through. I used Endomondo app to have a proper record of my journeys and proof that I have been there. After every trip, I prepared my next route in Google maps where it was easy to adjust streets to the next ones and mark points to revisit if I missed something.


Marshall Islands Navigation Charts

Marshall Islands Navigation Chart

Marshall Islands Navigation Chart

The arrangement of the sticks in these Marshall Islands navigational charts represents ocean swells & currents and how they interact with the land, useful information for navigating between islands via canoe. From a Smithsonian Magazine article about these charts:

The chart is less a literal representation of the sea, says museum curator and anthropologist Adrienne Kaeppler, and more an abstract illustration of the ways that ocean swells interact with land. Curved sticks, she explains, show where swells are deflected by an island; short, straight strips often indicate currents near islands; longer strips “may indicate the direction in which certain islands are to be found;” and small cowry shells represent the islands themselves.

The stick charts were preparatory & teaching tools — mariners would memorize the charts before heading out to sea rather than take them along on the boat.

Map of Areas Most Often Missing During Handwashing

With news of more than 70,000 confirmed cases and 1700 deaths from the COVID-19 virus, the importance of handwashing is once again front and center. Using data from a 1978 study on the hygiene of health professionals, this is a map of the most missed areas when washing hands.

Hand Washing Map

This more recent paper contains a short review of various studies of missed areas, most of which conclude that people often forget to wash their fingertips:

In 2008, the WHO designed a handwashing leaflet, making reference to Taylor, who indicated that the fingertips, interdigital areas, thumbs, and wrists are the most commonly missed areas in handwashing. Pan et al. also found that the tips of the nails and the fingertips had the largest amount of residual florescent stains left after handwashing among healthcare workers in Taiwan. The commonly missed areas among medical students in the study conducted by Vanyolos et al. was the first metacarpal, the proximal part of the palm (lateral), the distal phalanges, and the nail beds. In healthcare workers in Škodová et al.’s study, the thumbs and fingertips were the most commonly missed areas. In this study, the most frequently missed area was also the fingertips. However, the medial aspect and back of the hand were the second and third most missed areas, respectively. Moreover, the interdigital area and the front and back of the fingers were the least missed areas, which is in contrast to Taylor’s study.

So wash those fingertips! Here’s the CDC-recommended guide to washing your hands properly.

  1. Wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap.
  2. Lather your hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails.
  3. Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
  4. Rinse your hands well under clean, running water.
  5. Dry your hands using a clean towel or air dry them.

Long-time readers know that I like me some maps and in particular hand-drawn/homemade maps and maps of alternate realities. So I was charmed by Anna Calcaterra’s alternate map of the Americas, which features geographic entities like Long Chile, Ohio 2 (“Four Corners replaced w/ Ohio 2”), and East Dakota (RIP Minnesota). The kids are alright, y’all.


That ninety degree scenery thing

Landscapes Brilliantly Turned On Their Heads in This Digital Campaign

Some quite stunning work by Cream Electric Art created for an ad campaign for United Airlines in Australia. These are quite made-up by assembling two different landscapes in a dreamlike 90° angle but I’m posting them here to take us back to a favorite movie of mine, Inception, and the architect scene in Paris where Ellen Page’s character Ariadne bends the dream in a similar fashion. Less well known but even more interesting because it bent an actual map’s perspective was the dearly departed BERG’s Here & There project.

The projection works by presenting an image of the place in which the observer is standing. As the city recedes into the (geographic) distance it shifts from a natural, third person representation of the viewer’s immediate surroundings into a near plan view. The city appears folded up, as though a large crease runs through it. But it isn’t a halo or hoop though, and the city doesn’t loop over one’s head. The distance is potentially infinite, and it’s more like a giant ripple showing both the viewers surroundings and also the city in the distance.

Horizonless projection

That whole piece is a great read for a tour of perspectives from Alfred Wainwright’s hand-drawn walking maps, to China, to GTA and SimCity.


Hacking Google, a red handcart for red roads

red-handcart-1400.jpg

You’ve got to love little artistic hacks like this. Simon Weckert put 99 second-hand smartphones in a red handcart and walked around a few blocks in Berlin. Each phone was running Google Maps and being tracked for trafic measurements. Their presence and slow rolling around the streets caused Google to display a traffic jam.

The advent of Google’s Geo Tools began in 2005 with Maps and Earth, followed by Street View in 2007. They have since become enormously more technologically advanced. Google’s virtual maps have little in common with classical analogue maps. The most significant difference is that Google’s maps are interactive  - scrollable, searchable and zoomable. Google’s map service has fundamentally changed our understanding of what a map is, how we interact with maps, their technological limitations, and how they look aesthetically.

Maps of Every Single Street in Any City

Andrei Kashcha’s City Roads tool will draw you a map of just the roads in any city around the world. I’m in Saigon right now, so I did that one first:

Saigon, just the streets

And this is Paris:

Paris, just the streets

I love that the whitespace reveals more of a city than just roads — you can also see rivers, parks, train lines, stadiums, and airports.

See also Ben Fry’s All Streets project and Nelson Minar’s map of all the rivers in the US.

Update: Javier Pastor compiled a list of similar services that create artistic maps. The article is in Spanish but Google Translate works well on it.


10-Year Time Lapse of US Weather Radar

Sometimes I load up the US map on Weather Underground just to watch storm systems tumbling and swirling across the country, so this 2-hour time lapse of the last 10 years of US weather radar is riiiiight up my alley. You don’t have to watch the whole thing — even dipping in here and there for a couple of minutes is really gratifying. Can you get ASMR from a weather map? (thx, benjamin)


World Map Projection, But All South Americas

I bet you never noticed that South America can kind of approximate most of the world’s other continents pretty well. XKCD’s Randall Munroe did and made a bad map projection of it.

This is only slightly worse than the Mercator projection tbh.


A Map of Mormon Geological Theology

Boston Rare Maps recently sold a nine-foot-high cloth map from 1899 that shows a geographic interpretation of the Book of Mormon.

Mormon Map Banner

The map was an official production of the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS) in Independence, Missouri. The RLDS (known since 2001 as the Community of Christ), is a reformist branch of the Church of Latter Day Saints, established in 1860.

You can read more about the proposed setting of the Book of Mormon on Wikipedia and its adherents’ belief that the indigenous peoples of the Americas are descended from Israelites.

The Book of Mormon is based on the premise that two families of Israelites escaped from Israel shortly before the sacking of Jerusalem by Nebuchadnezzar and that they constructed a ship, sailed across the ocean, and arrived in the New World as founders of Native American tribes and eventually the Polynesians. Adherents believe the two founding tribes were called Nephites and Lamanites, that the Nephites were white and practiced Christianity, and that the Lamanites were rebellious and received dark skin from God as a mark to separate the two tribes. Eventually the Lamanites wiped out the Nephites around 400 AD, leaving only dark skinned Native Americans. The descent of Native Americans from Israel is a key part of The Church of Jesus Christ of Latter-day Saints’s foundational beliefs.

Huge Hand-Drawn Map of North America 5 Years in the Making

Anton Thomas Map

Anton Thomas Map

Anton Thomas has been working for the last five years on a huge hand-drawn map of North America.

North America: Portrait of a Continent is drawn completely by hand with colour pencil and pen. It is a 5 x 4 feet (150 x 120 cm) perspective projection of the entire region, spanning from Alaska to Panama; Greenland to the Caribbean. There are tens of thousands of features, including 600 individual cities and towns.

Looks fantastic. He finished it in February and is getting ready to open pre-orders for prints sometime this month.

Update: Prints of the map are available on Thomas’ store. He also made a video tour of the Mississippi River, in which he shares what all the little details on the map signify along the river’s meandering course.


Get Prints of Eleanor Lutz’s Genius Infographics

I’ve featured the maps and science infographics of Eleanor Lutz for years here. You might be interested to learn, as I did the other day, that you can get posters and prints (and iPhone cases and tshirts) of a bunch of her work at Red Bubble. Like this map of the geology of Mars or the butterflies of North America.

A Map of the 637 Languages Spoken in NYC

NYC Language Map

The Endangered Language Alliance has produced a map of the 637 languages and dialects spoken by the residents of NYC (past and present).

It represents ELA’s ongoing effort to draw on all available sources, including thousands of interviews and discussions, to tell the continuing story of the city’s many languages and cultures. The patterns it reveals — the clustering of West African languages in Harlem and the Bronx, a microcosm of the former Soviet Union in south Brooklyn, the multifaceted Asian-language diversity of Queens, to name a few — only hint at the linguistic complexity of a city where a single building or block can host speakers of dozens of languages from across the globe.

The online map embedded in the page works ok, but a $50 donation to the organization will get you a 24″ x 36″ print for your wall.

According to a Gothamist post about the map, the size and diversity of the city sometimes means that a significant chunk of a language’s worldwide speakers live in NYC:

Seke is a language spoken in just a handful of towns in Nepal-worldwide, there are fewer than 700 people who speak it. More than 100 of those people live in Brooklyn and Queens, according to the Endangered Language Alliance, a group that seeks to document and preserve smaller, minority, and Indigenous languages across New York City.

Six Maps that Reveal America’s Expanding Racial Diversity

Using 2020 census estimates, a series of six maps and the accompanying article from William H. Frey at the Brookings Institution show how the racial makeup on the United States is expected to have changed since the last census in 2010.

Map Census 2020

Hispanics and Asian Americans are the fastest-growing racial minority groups nationally, increasing by 18.6% and 27.4%, respectively, from 2010 to 2018. There is also a growing dispersion of both groups to new destinations, which tend to lie further afield than the familiar large metro areas.

In 1990, 39% of all U.S. Hispanics resided in just four metro areas: Los Angeles, New York, Miami, and Chicago. In 2018, 39% of U.S. Hispanics resided in seven metro areas, with Houston, Riverside, Calif., and Dallas added to the list (and each eclipsing Chicago in size). And beyond these, Hispanic growth is high in areas with smaller Hispanic settlements in all parts of the country.

Distorted US Map of Where Candidates Campaigned in 2016

Because of the Electoral College and the way the primary system works in the US, presidential candidates end up spending a disproportionate amount of time is so-called “battleground states” like Pennsylvania, Ohio, and our dysfunctional friend Florida and primary states like Iowa and New Hampshire and less time where most of the US population actually lives (NY, CA, TX, IL, and in cities). The campaign for the National Popular Vote has produced a map that shows where the candidates did campaign events in 2016:

Map Campaign Time

Because of these state winner-take-all statutes, presidential candidates have no reason to pay attention to the issues of concern to voters in states where the statewide outcome is a foregone conclusion. In 2012, as shown on the map, all of the 253 general-election campaign events were in just 12 states, and two-thirds were in just 4 states (Ohio, Florida, Virginia, and Iowa). Thirty-eight states were completely ignored.

And here’s the map for the 2012 election, which is even more extreme:

Map Campaign Time

State winner-take-all statutes adversely affect governance. “Battleground” states receive 7% more federal grants than “spectator” states, twice as many presidential disaster declarations, more Superfund enforcement exemptions, and more No Child Left Behind law exemptions.

Also, because of state winner-take-all statutes, five of our 45 Presidents have come into office without having won the most popular votes nationwide. The 2000 and 2016 elections are the most recent examples of elections in which a second-place candidate won the White House. Near-misses are also common under the current state-by-state winner-take-all method of awarding electoral votes. A shift of 59,393 votes in Ohio in 2004 would have elected John Kerry despite President Bush’s nationwide lead of over 3,000,000 votes.


The Bear with Its Own ZIP Code

Today I learned that ZIP Codes do not strictly represent geographic areas but rather “address groups or delivery routes”.

Despite the geographic derivation of most ZIP Codes, the codes themselves do not represent geographic regions; in general, they correspond to address groups or delivery routes. As a consequence, ZIP Code “areas” can overlap, be subsets of each other, or be artificial constructs with no geographic area (such as 095 for mail to the Navy, which is not geographically fixed). In similar fashion, in areas without regular postal routes (rural route areas) or no mail delivery (undeveloped areas), ZIP Codes are not assigned or are based on sparse delivery routes, and hence the boundary between ZIP Code areas is undefined.

The White House has its own ZIP Code (20500), as does the shoe floor of Saks Fifth Avenue in NYC (10022-SHOE). US mail to Santa Claus gets sent to the town of North Pole, Alaska (99705) but in Canada, Santa gets his own postal code (H0H 0H0). And Smokey Bear has his own ZIP Code (20252) because he gets so much mail.

ZIP Codes are therefore not that reliable when doing geospatial analysis of data:

Even though there are different place associations that probably mean more to you as an individual, such as a neighborhood, street, or the block you live on, the zip code is, in many organizations, the geographic unit of choice. It is used to make major decisions for marketing, opening or closing stores, providing services, and making decisions that can have a massive financial impact.

The problem is that zip codes are not a good representation of real human behavior, and when used in data analysis, often mask real, underlying insights, and may ultimately lead to bad outcomes. To understand why this is, we first need to understand a little more about the zip code itself.

For instance, in Miami’s 33139 ZIP Code the difference between the highest median income (as measured in much more granular US Census Block Groups) and lowest median income is over $240,000. So you can imagine it would be difficult to know or even assume anything in general about those residents based on their ZIP Code alone.
