12 Maps that Changed the World


 The Waldseemuller Map of the World, #5 in The Atlantic’s list of 12 Maps that Changed the World

“This work by the German cartographer Martin Waldseemuller is considered the most expensive map in the world because, as Brotton notes, it is "America's birth certificate"—a distinction that prompted the Library of Congress to buy it from a German prince for $10 million. It is the first map to recognize the Pacific Ocean and the separate continent of "America," which Waldseemuller named in honor of the then-still-living Amerigo Vespucci, who identified the Americas as a distinct landmass (Vespucci and Ptolemy appear at the top of the map).  The map consists of 12 woodcuts and incorporates many of the latest discoveries by European explorers (you get the sense that the woodcutter was asked at the last minute to make room for the Cape of Good Hope). ‘This is the moment when the world goes bang, and all these discoveries are made over a short period of time,’ Brotton says.”

When I mentioned this website from The Atlantic, “12 Maps that Changed the World,” to some friends (non-map people), they were rather astonished.  They had a hard time grasping the concept that maps could change the world, or even be very important to our lives in any way.  Check out this (article from The Atlantic) at http://m.theatlantic.com/international/archive/2013/12/12-maps-that-changed-the-world/282666/?google_editors_picks=true  NOTE: Best viewed in Chrome; Internet Explorer seems to distort the images, for some odd reason.  Thanks, Christopher Herrmann, for sending me the link.

I would agree with most of their picks - who could dispute the importance of maps by Ptolmey, Al-Idrisi, the T-in-O Mappa Mundi, Waldseemuller, Mercator, the Gall-Peters projection, and so forth - although a couple of their top 12 seem rather removed from global significance, to my mind, but nevertheless they are all fabulous maps/mapping efforts.  My list would probably be a bit different, and I don’t think I would be able to pick just 12!  (I have a problem restricting myself!)  I might have added in or substituted the following 12 maps (in no particular order of importance):

1.
John Snow’s 1854 map of cholera cases in mid-19th century London, which was one of the most significant jump starts to medical geography/spatial analysis, and the discovery/evidence of the links between disease and environment (see my blog post http://geographer-at-large.blogspot.com/2013/03/cartographies-of-life-and-death-john.html on John Snow’s map). 


John Snow’s map, pinpointing cholera deaths and the location of public water pumps in Soho, London. 

2.
The US Public Land Survey System (PLSS), begun in about 1785 at Thomas Jefferson’s behest, which platted townships and sections in most of what is now the United States, and which basically laid an imaginary grid over the whole country in the spirit of the rational age of the Founding Fathers.  The PLSS shaped the landscape of the entire continental US (outside of the original 13 colonies and a few other earlier-settled eastern states);

3.
The UK Ordnance Survey (definitely!) which was extremely influential and innovative, and set the standard for many national mapping programs (including the massive effort of mapping the Indian subcontinent), and introduced many ground-breaking surveying and cartographic techniques.  The OS maps are still vitally important today, and many visitors to the UK who use the maps marvel at the extreme detail and the very large scale – some series are 6 inches to the mile! See http://geographer-at-large.blogspot.com/2011/08/map-addict.html

4.
On a more localized level, in terms of impact, the maps resulting from the surveyor’s mapping of the Mason-Dixon Line between north and south U.S., with its very real ramifications on people’s lives in the 19th and even 20th centuries.  The Mason-Dixon line was surveyed in 1763-1767 in response to a border dispute between some of the American colonies prior to the Revolutionary War.  It has become understood in the conventional wisdom to symbolize a cultural boundary between the northern and southern states, and also served (unintentionally) as a rough line of demarcation separating slave-holding states from states where slavery was illegal.  This line was unofficially extended out as the country grew westerly, and the subsequent maps that resulted depicted the country divided into slave and non-slave states, as famously seen in the Abraham Lincoln painting of signing the Emacipation Proclamation;    http://www.finebooksmagazine.com/issue/1104/mason-dixon-2.phtml

The map prepared by the surveyors Mason and Dixon, on behalf of the Royal Astronomical Society in Greenwich, UK, using some instrumentation and methods not readily available to colonial surveyors, which increased the accuracy of the survey.

5.
The 1811 Commissioner’s Plan for the proposed gridiron layout of NYC, which more or less created the real estate frenzy that continues to define New York City, not to mention the uniquely simple and topography-erasing street pattern of Manhattan, which persists to this day.  The grid plan for NYC was in keeping with the US PLSS, and influenced many cities to adopt the rationality and ease of wayfinding of the grid, thus rejecting the more organic form that most European cities had as an artifact of the mediaeval era.

6.
The map that al-Hassan ibn-Muhammad al-Wezaz al-Fasi (aka Leo Africanus) prepared for Pope Leo X in about 1520, based on geographical knowledge from of Leo Africanus’s own extensive travels, and which showed as never before to Western eyes the reality of northern Africa and the Middle East.   See http://geographer-at-large.blogspot.com/2011/04/leo-africanus-15th-century-geographer.html


A detail of the 1520 Leo Africanus map, derived and compiled from a collection of maps Leo was traveling with when he was captured by pirates in the Mediterranean Sea.  These maps helped save Leo’s life from the pirates, since he had no one to ransom him, and so was otherwise worthless to them, but he did have the maps, which the pirates recognized as valuable.  They sold Leo Africanus (and the maps) to the Pope as a slave. 

7.
In that vein, I would also have to include The Catalan Atlas, 1375, by the Jewish cartographer Abraham Cresques of Majorca, Spain, which was partially a type of Portolan navigational chart, a cutting-edge and more accurate technique at that time, and the map was also considered to be the most complete picture of geographical knowledge as it stood in the later Middle Ages.  See: http://geographer-at-large.blogspot.com/2011/04/rediscovering-african-geographies.html

8.
Speaking of Africa, how could we neglect to mention the famous Berlin Conference of 1884-1885 (also known as the Congo Conference) where Africa was divided up on a map amongst all the major European powers of the day.  That dividing-up map still reverberates today with the borders of countries having nothing to do with tribal areas, language or cultural groups of the indigenous peoples, dividing people who should have been kept together, and putting together people who didn’t want to be together, and based solely on “equitably” spreading out the “spoils” of African resources amongst the European colonials who had footholds in various parts of Africa by then.  Many consider this map to be the un-doing of Africa.  See http://geographer-at-large.blogspot.com/2011/04/rediscovering-african-geographies.html

9.
The 1602 Matteo Ricci map of the world.  Ricci was a Jesuit priest who traveled as a missionary to China in 1583.  In 1602, Ricci and his Chinese collaborators created the first map of the world in Chinese, now called “The Impossible Black Tulip of Cartography,” because of its rarity, importance, and exoticism.  Its name in Chinese is Kūnyú Wànguó Quántú; literally “A Map of the Myriad Countries of the World”; in Italian, “Carta Geografica Completa di tutti i Regni del Mondo;” or “Complete Geographical Map of all the Kingdoms of the World,” printed in China at the request of the Chinese Emperor.   


This is a later variation of Ricci's map.  The original 1602 Ricci map is a very large, 5 ft (1.52 m) high and 12 ft (3.66 m) wide, xylograph of a pseudocylindrical map projection, showing China at the center of the known world.  Its projection is similar to the 1906 Eckert IV map.  It is the first map in Chinese to show the Americas.  It was originally carved on six large blocks of wood and then printed in brownish ink on six mulberry paper panels, similar to the making of a folding screen.  See:  http://geographer-at-large.blogspot.com/2011/06/method-of-loci-memory-palace.html

10.
Olaus Magnus’s 1539 Carta Marina – a map of the ocean showing the Northern Lands.  See http://geographer-at-large.blogspot.com/2012/04/motw-4-23-2012ultima-thule.html It is a very large map, about 5 ½ feet wide by 4 feet high.  “Magnus' map of the great northland was a fantastic achievement, its stature undeterred by the liberal use of sea monsters and other fanciful creatures.  The detail in the coastlines (as well as the depiction of currents between Iceland and the Faroe Islands) as well as interior features make these among the most detailed maps of the north yet printed in the 16th century.”

11.
Joseph Minard’s 1869 flow map showing a detailed and longitudinal view of Napoleon’s 1812 march into Russia, which ended so disastrously for the French troops.  There are a number of variables portrayed in this 2-dimensional figure, which very beautifully conveys a complex set of information, according to the wiki entry for Minard:
§  the size of the army - providing a strong visual representation of human suffering, e.g. the sudden decrease of the army's size at the crossing of the Berezina river on the retreat;
§  the geographical co-ordinates, latitude and longitude, of the army as it moved;
§  the direction that the army was traveling, both in advance and in retreat, showing where units split off and rejoined;
§  the location of the army with respect to certain dates; and
§  the weather temperature along the path of the retreat, in another strong visualisation of events (during the retreat "one of the worst winters in recent memory set in").
Étienne-Jules Marey first called notice to this dramatic depiction of the fate of Napoleon's army in the Russian campaign, saying it "defies the pen of the historian in its brutal eloquence"[ Edward Tufte says it "may well be the best statistical graphic ever drawn" and uses it as a prime example in The Visual Display of Quantitative Information.
Howard Wainer identified Minard's map as a "gem" of information graphics, nominating it as the "World's Champion Graph
Minard was a pioneering cartographic and graphic designer, creating some of the first maps using pie graphs and other then-novel ways of mapping data.

The Blue Marble satellite image of Earth - In some ways, these “pictures” of the whole earth from space have been instrumental in revising the average human’s mindset about our puny and tenuous existence in the universe, promoting the opposite of a geo-centric outlook, while at the same time reminding us earth-dwellers of our possibly unique place in the scheme of things and how fragile our planet actually is.  “This NASA moving image, recorded by satellite over a full year as part of their Blue Marble Project, shows the ebb and flow of the seasons and vegetation. Both are absolutely crucial factors in every facet of human existence -- so crucial we barely even think about them. It's also a reminder that the Earth is, for all its political and social and religious divisions, still unified by the natural phenomena that make everything else possible.”

Worthy Runners-Up:

A.
Charles Booth’s 19th century Poverty Maps of London, perhaps the first thematic maps with extensive use of socio-economic mapping, and his exhaustive ground-truthing methods of information gathering. 


B.
Danny Dorling and teams’ Worldmapper Atlas of global conditions, using his amazingly effective and innovative cartogram technique.  
For more of Dorling’s work, see:
World Population by Country

C.
Baron Alexander Von Humboldt’s isotherm map of temperature.  He developed the first isotherm maps as well as some other interesting new ways of geo-visualizing natural data in 2-dimensions.  He focused mainly on the New World, and was an inveterate traveler, being in many cases the first person mapping areas in South America and other parts of “The Kingdom of New Spain,” including Mexico, Texas, and parts of what is now the American Southwest.  He was also possibly the first person to proclaim that the continent of South America “fit” into the shape of Africa, and at one time they were probably joined landmasses.  There is an important Pacific current named after him, a cold current from Antarctica that comes up the west coast of South America and allows penguins to thrive in the Galapagos Islands on the Equator.

D.
Dr. Robert Perry’s 1844 maps of fever epidemic as connected with socio-economic and housing conditions in Glasgow, Scotland.  One of the first of its kind, and pre-dates the influential John Snow cholera maps by a decade, and the Charles Booth Poverty Maps by 40 years.  The map uses local medical reports, statistical tables and a color-coded map of the city to highlight the link between poor sanitation, poverty, and poor health.  It is an excellent example of early thematic mapping, and pre-dates both Charles Booth’s Poverty Maps of London (1886-1903), and John Snow’s cholera maps of Soho, London (1854).  Perry’s map, with different neighborhood areas colored differently to designate the severity of the epidemic, made it obvious that the effects of the epidemic were not distributed evenly throughout the city, but disproportionately affected the poorest, most densely settled areas, where as many as 20% of the population had succumbed to the disease.  See more on Robert Perry and the 1843 fever epidemic at http://special.lib.gla.ac.uk/exhibns/month/feb2006.html.

E.
German propaganda maps from the 1930’s which helped sway opinion as to the righteousness of Germany occupying neighboring countries to allow for their famous “elbow room” to grow the German race and reclaim formerly German territories. 


Typical propaganda map symbols: (a) arrows represent pressure on Germany from all sides; (b) circle signifies the encirclement of Germany before and after WWI; (c) pincers personify the pressure against Germany from France and Poland from the west and east.

Of course, my list is heavy on the historically significant maps, and unfortunately this means that I have given short shrift to modern-day cartographers and geovisualizers, mainly because they haven’t had sufficient time to demonstrate their importance yet!  There are all kinds of potentially influential maps being produced today, which is, of course, part of what my blog attempts to bring to light. 


In 2010, the British Library had an exhibit on the World’s Greatest Maps.  For their picks, see:

Map of the Week 2-20-2012:Ancestry and Immigration


The Largest Ancestry groups in the United States, by state and by county, based on Census 2000 data, from: http://www.usa.org/demographics/

This is an oldie but goodie (from 2006), and I found this very interesting – a map of the United States, by county (and also shown by state in the upper right of the layout) identifying the largest ancestry group for the population in each.  When you look at the map by state, it is amazing how many states have German as their largest ancestry group.  It’s no wonder that at one time German was seriously being considered as a primary language instead of or in addition to English - this would have been between the late 18th century through the early 20th century, but prior to WWI, when German became verboten since the U.S. was fighting them in the war.  Although this is often thought of as a legend or myth, (see http://www.watzmann.net/scg/german-by-one-vote.html) it is true that in certain places (like New York City, St. Louis, Cincinnati, and much of Pennsylvania) there was probably more German spoken at home, in the streets, in the workplaces, and in the churches than anything else.  I suspect, looking at this map, that it was the same story in some of the Midwestern states.  The Midwest also has some smaller pockets of predominantly Norwegian, Dutch, and Finnish ancestry.  However, as was the case with many later immigrant groups from Europe, people tried to assimilate and fit in, and oftentimes jettisoned their native languages in favor of English so as not to appear any more foreign than they had to, and so that they would not be considered outsiders.  Often immigrants would purposely not teach their children the language of their homeland, preferring the children to only speak English, so they would have an easier time in school, getting jobs, and finding better places to live.  There was a lot of prejudice against foreigners in the U.S. (some things never change).
I find the counties (mainly in the southeastern states) identified as having “American” ancestry to be thought-provoking.  What could that mean?  We all came from somewhere else, except the Native American Indians (who also came from somewhere else, but a very long time ago).  Does this mean they (the self-identified “Americans”) don’t know where their ancestors came from?  Or they feel they have been here so long they are entitled to say their ancestry is all “American”?  Or that they are so multi-culti that they couldn’t pick just one national/ethnic group as their ancestors?  I would have thought this later problem would have occurred most often in big city “melting pots” not in relatively homogenous rural mountain areas.  Some of the readers’ comments on this topic on the website include the following: “I guess 5 generations of hillbilly isn’t a listed checkbox”  (mean and snarky!) and “I believe ‘American’ translates to Scotch-Irish ancestry, as that’s the dominant Caucasian ancestry for pretty much all of those areas covered by the label.”  Yes, I think that many people don’t think of themselves as having any ethnicity other than American when their ancestors have been here for a few hundred years. 
Also, the census allows you to check off more than one box for ancestry (this info was collected on the long form in 2000, in other words it is a sample of the total population, but now I’m not sure how it works since they did away with the long form in the 2010 census), so some of this maybe double-counting ancestries.  In any event, according to the 2000 census, about 1 in 6 Americans list their ancestry as “German,” making it the largest ancestry group in the U.S.  However, there are nay-sayers, who argue that if you combine all the British groups (English, Irish, Scots, Scots-Irish, Welsh, Canadian (?), etc.,) and the people who ARE of that heritage checked that off instead of “American,” British would be the largest ancestry group.  I think this whole thing is pretty tricky, many Americans don’t really know where their ancestors are from, or they just don’t think about it in those terms, and also you realize that you hardly ever meet anyone who tells you their ancestry is “English” or “British,” especially when their ancestors have been here since colonial days.  (Unless they belong to the Daughters of the American Revolution or descended from the Mayflower pilgrims or something equally high falutin. Or unless they are immigrants from the UK themselves, or first generation with parent(s) from the UK.)
Now, if you look at New York State, although there are many counties identified as having German, Irish, or English (and French in the New York State counties bordering French Canada) as their dominant ancestry, when you look at it on the state version of the map, Italian is the dominant ancestor group.  This is true of New Jersey, too, I guess no big surprise there, as anybody who has watched Jersey Shore can attest (only kidding!  No hate mail please! I love NJ!)

And now, for a REAL oldie but goodie, Charles Joseph Minard’s “Carte figurative et approximatative represéntant pour l’année 1858 les émigrants due globe,” or a flow map of immigration around the world.  From the American Memory site http://memory.loc.gov

This is another wonderful example of data visualization by Monsieur Minard, he of the seminal graphic depiction of Napoleon’s Russian Campaign of 1812, a graph/map that charts the course and attrition rate during Napoleon’s doomed march on Russia – well known to all Edward Tufte devotées (“The Visual Display of Quantitative Information”).  This map of global immigration was produced in 1862, and rather ingeniously synopsizes the primary routes of migration in 1858.  I tried to find a higher resolution version, but was unsuccessful.  Nevertheless, by zooming in on this one, it is possible to decipher most of the legend, which is in French, and also somewhat confusingly vacillates between naming the countries of origin of the immigrants or the ports they departed from. 
So, from the Legend's top, the green is from “England,” (strangely enough, Ireland is not shown, even though in 1858 it would seem that many of the British immigrants were still coming from Ireland in the wake of the great famine.  Most of the English in 1858 were headed toward the Unites States, Canada, but mostly to Australia); the pink is from “Hamburg and Bremen” (these are the major German ports immigrants departed from in Germany, cities in the old Hanseatic League.  In 1858, when this map was made, this was prior to the unification of Germany, so these numbers of immigrants might include those from other parts of what is now or was then Germany, such as Prussia, Pomerania, Bavaria, Saxony, etc., other neighboring European countries such as Poland, and some of the Scandinavian countries, such as Denmark, as shown by the narrower pink line); teal lines denoted immigrants from France (notice the line linking France to Algeria); grey lines were immigrants from Portugal (going mainly to Brasil, as were some French and Germans); Brown were immigrants from Africa (at this time there was only a relatively small amount of illegal slave trade to most of the Americas, the trade from Africa having been outlawed in 1808 in the US, and 1807 in England and her colonies, [this outlawed the importation of enslaved people, not the institution of slavery itself, which obviously continued apace in the US and other countries for decades longer], but notice still a line linking west central Africa to Jamaica and Trinidad.  This may have been the people from the Congo who went to these Caribbean outposts of England as indentured servants, more like serfs than slaves, but they were voluntary immigrants.  The thickest line from Africa in 1858 led to the Indian Ocean Islands off the coast of Africa – the islands of Reunion and Mauritius, French colonies);  Yellow designates Chinese immigrants (headed towards the west coast of the US where they built the railroads and participated in the gold rush activities, but they also went in numbers to Australia and the Caribbean); and tan were immigrants from India (notice how the lines from India go to the Anglophone Caribbean and British Guyana, in part to make up for the nearly complete stoppage in the trans-Atlantic slave trade from Africa, and the actual emancipation of slaves in many Caribbean islands by the 1830's.  The Indians came as indentured servants, for the most part, to work the plantations and assume other labors formerly performed by African slaves). 
It’s difficult to see, but the lines have numbers written on them, indicating the numbers of immigrants.  1858 was prior to the great migration to the US from eastern and southern Europe and from Russia, which happened later in the 19th and early 20th centuries.  All in all, a fascinating snapshot of immigration in mid-19th century, a time of great political upheaval and social unrest in the world, and at the height of industrialization and all its attendant evils.  Of course, it’s a very coarse snapshot, and much detail and nuance is omitted, but nevertheless a pretty good effort, considering the paucity of data that Minard likely had at his disposal back then.  A comprehensive bibliography of the graphic works of Charles Joseph Minard can be viewed at http://www.datavis.ca/gallery/minbib.php

While we are on the subject of immigration, here is something a bit more recent, a map of the status of immigration laws in the United States. 

            And just to round it out, since talk of immigrants and immigration (at least in the U.S., but I think unfortunately in many other countries, as well) comes back around to hatred and intolerance, here is a map of Hate Group locations in the U.S. (Please ignore the weird projection.)
