Map of the Week 12-05-2011:New “Dencity” Method to Map Global Population


New visualization technique to map population density, by Fathom at http://fathom.info/dencity/  The map also highlights the 20 most populous cities in the world today. 

“Dencity maps population density using circles of various size and hue.  Larger, darker circles show areas with fewer people, while smaller, brighter circles highlight crowded cities.  Representing denser areas with smaller circles results in additional geographic detail where there are more people, while sparsely populated areas are more vaguely defined.” 
            This map was created in response to the new milestone our planet has reached in being the home to more than 7 billion people.  This map shows it’s not about absolute quantity, it’s about density.  Not only are the dots smaller and closer together in the more densely populated parts of the world, but they are also brighter, which intuitively makes us think of these highly populated areas as glowing and vibrant. Perhaps this represents a little bit of unintended editorializing through visualization (or "visualitorializing," to coin a new word) on Fathom's part, or maybe even subliminal message-making, but these high-density areas DO tend to be the incubators of innovation and invention.  In a bit of a twist on typical cartographic convention, such as in proportional symbol maps, the smaller dots signify MORE of the quantity being mapped.
           
“China. The largest city in the world is Beijing, with 17.8 million people.  China is home to six of the twenty most populous cities in the world, more than any other country.” Gridded Population Density Map by CIESIN from:  http://sedac.ciesin.columbia.edu/gpw/maps/globaldens.pdf
Our friends and colleagues at CIESIN (Columbia University’s Center for International Earth Science Information Network) wonder if this Dencity map is an improvement over their own gridded population map, and whether or not it is showing anything new.  Although ostensibly they are both mapping the same population density data (more-or-less: the CIESIN map is based on Year 2000 data and the Fathom map is based on more current population data), I would say that the Fathom map, first of all, is more gorgeous, and second of all, probably does a better job of highlighting the bursts of population density, and making it much more obvious where population density is most intense. It gives a better overall snapshot of population density at-a-glance, although it's very likely that the CIESIN method produces a more accurate and "scientific" map.  See CIESIN's data and methodology at http://sedac.ciesin.columbia.edu/gpw/
          Of course, grid-based cartograms are another way of depicting population density (as reviewed on a recent blog posting at http://geographer-at-large.blogspot.com/2011/10/map-of-week-10-17-2011-gridded.html)

Magnificent Maps: Snow, Taxi Cabs, Road Kills, Factory Farming, More Crime!, Victorian Infographics, and the Service Ecology of a City

“The Island satirises the London-centric view of the English capital and its commuter towns as independent from the rest of the country.”  From the exhibit “Magnificent Maps” at the British Library

Magnificent Maps: Snow, Taxi cabs, Road Kills, Factory Farming, More Crime!, Victorian Infographics, and the Service Ecology of a City (to name but a few......).

Oh my, what a mélange!  OK, so none of these topics is connected to any of the others in any way, other than they are all links to cool maps that you guys have sent to me here-lately.  It’s a nice snowy day (where I am, at least!) so a great day to look at cool maps. 

Snow Maps - NYC

OK, folks, the links are coming fast and furious!  This just in from Holly Porter-Morgan, and it's very pertinent to our snowy conditions today.  Take a look, and if the road clearing is bad in your neighborhood, now you have a way to "mappily" address it.  JAM

“Thinking about VGI and interactive maps today and I found some great and very timely examples online.  Feel free to send around!” 

Starting off, we have the official NYC gov effort.

NYC Snow Update

The NYC map is actually the nicest looking, but that may just be my opinion, because so many interactive maps/mash-ups use Google Maps these days and NYC created their own interactive map (not that the rest of us have the time or money to do that).  This map offers different symbol styles and colors for different reported problems.  It features three categories for a report submission:  Stuck vehicle, Street not clear of snow, and Street clear of Snow.  On the down side, all categories refer to points and none to lines (which are shown in the third map listed).  

  
Mapping Snow Removal in Brooklyn
Has your street been cleared?

I found this on Brooklyn Vegan under the link ‘Report your Brooklyn Snow Problems- Plot them on an Interactive Map. It won’t get your street plowed any faster, but it might make your feel better’.

This interactive map built on the Google Maps interface, which appears to remain active, displays a point for every submitted problem report.  The map viewer can display the reports all in red  (All Categories)  or choose from the various other point colors to see different types of problems reported:   Failure to Remove Snow Reports (purple) ,  Stalled Vehicles & Other Problems Reports (blue) , and Time of Snow Removal Reports (brown).


 Also, going back to the snowstorm just after Christmas, there is the “Roadify Plowed Street Map NYC Dec 2010”, which is still live.

Another map built on the Google Maps interface, the page stated ‘edit the map or tell us and we'll do it for you. Just email info@roadify.com or tweet @roadify’.   Kudos to the creators for using Twitter as a way to get information for the map.  Roads that were reported as not plowed were indicated in red, with a few plowed roads indicated in green.  This map went live on Dec 28th and was last updated on Dec. 30th.


Victorian Infographics


Tinted drawing showing the comparative lengths of rivers and heights of mountains worldwide. In: 'General Atlas Of The World: Containing Upwards Of Seventy Maps,' by Adam & Charles Black, Sidney Hall and William Hughes, 1854; published in Edinburgh by A & C Black.

Here is something else to keep you guys occupied and amused on this snowy afternoon - Victorian infographics!  Lesley Kunikis just sent these to me, and they are gorgeous and complicated examples of how crazy people can get graphically. These people had all the patience in the world to construct these diagrams.   Check them out - they are really something! 

“Here are links regarding Victorian infographics... pretty cool!”

Taxi cab travel maps/graphics/diagrams/whatever! VISUALIZATIONS! 

And here’s some more!

One-Hour of NYC Taxi Trips in One Graphic

From Matthew Croswell:
“Hey Map Monkey,
This is Matt Croswell (work email). I came across this interesting graphic. Although it is not your traditional map, a group mapped taxi trips between 4-5 PM in Manhattan. Pretty interesting, especially the amount of trips within the same neighborhood.
-Matt”


Note to those of you who don't ride in taxis often: between 4 and 5 PM is the dead zone in trying to get a taxi.  4 PM is when the drivers' shifts change, and taxis in Manhattan are scarcer than hens' teeth!

The Service Ecology of a City:

From Amy Trexler:
“This website prevents me from doing work all day long.”

Leave it to a zany Dutchman to have a great design blog like this one!  Check out his posting called “Spaced Out in a Flat World,” too. 



Nutrire Milano (Feeding Milan) is also exploring the relationships between food systems, service innovation, and sustainable urban development. A project of the Slow Food Movement with Milan Polytechnic, Nutrire Milano also uses maps to highlight where there are gaps or blockages in the ways food is produced and distributed.


More Crime Maps!

And, just in from Carrie Beth Lasley (she is in New Orleans):

“The local paper, the Time-Picayune, has been running daily crime maps. This is part of the new Police Chief's effort to engage more with the public. Here's a link to one. They do it district-by-district every weekday on the Web.

Factory Farms

From Dan Kulakowski:

“I thought this was a pretty cool map, and presented another reason for me to be happy to not live in the middle of the country.”

http://www.factoryfarmmap.org/#animal:all;location:US;year:2007
However, Dan, New York State is not immune from the bad impacts of factory farming, either.  As one of the facts on the website states: “The nearly 213,000 dairy cows on factory-farm dairies in New York produce as much untreated manure as 47 million people -- two and a half times the population of New York.”  A sobering thought…and believe it or not, the amount of factory farming in NY State has increased quite significantly in the past 10 years, according to the charts on the web page.


Magnificent Maps


Detail of the Fra Mauro Map, part of the exhibit at the British Library
From Brian Morgan:

“Here's a cool online map exhibit from BBC 4 to spend some time exploring.  There's some really nice stuff in here, you might want to pass it along to students or anyone else who might enjoy it.”

This is where you can look in detail at the maps.

Very cool stuff!  Check out the “Explore Themes” function when you get to the individual maps, for instance Fra Mauro’s 1450 map of the world. 

And speaking of the good brother, Fra Mauro, before the spring term starts, and if you have nothing in particular to do to while away the hours, I very much recommend a tiny little book called “A Mapmaker’s Dream: The Meditations of Fra Mauro, Cartographer to the Court of Venice,” by James Cowan, 1996.  Very inspirational! 


This is the BBC video about the exhibit.

This is something called “MapTube,” sort of the “YouTube” of Maps!

Road Kills

From Holly Porter-Morgan:

“Please send on to the group if you find it relevant.”


This one is about the guy who is mapping road kills on thousands of miles of roads.  OK, now for those of you who have taken my fall class in environmental modeling and spatial analysis, you may remember one of the papers I tortured you with (oops!  I mean one of the scintillating papers you very willingly read and re-read multiple times) about the mitigation of highway road kills in the Canadian Rockies, and how the favorite paths of the various focal species were estimated by aspect, slope, etc., (remember “expected” versus “observed”?).  It seems this poor fellow doing this incredible road kill ground truthing work could benefit from parts of their approach. 

And, lastly, Katie Gill sent me this just tonight, which relates, by coincidence, to the same type of highway mitigation project.  In fact, one of the species they are most concerned about in this project, the lynx, was one of the focal species from the Canadian Rockies highway mitigation project.
