A gallery of network visualizations
Nov 21st, 2005 by Tom Johnson


Just received a reference to this gallery of  network
visualizations.  The site is new to me, but perhaps not to all of
you.
http://www.visualcomplexity.com/vc/index.cfm 

Be sure to drill down in the “About” link for additional riches. 
There are hints of potential here but for the fact that much of the
design is in the ever-so-cool black and gray, which means
it's a chore to extract any meaning.
___________________________________________________

Goal

VisualComplexity.com
intends to be a unified resource space for anyone interested in the
visualization of complex networks. The project's main goal is to
leverage a critical understanding of different visualization methods,
across a series of disciplines, as diverse as Biology, Social Networks
or the World Wide Web. I truly hope this space can inspire, motivate
and enlighten any person doing research on this field.

Not all projects shown here are genuine complex networks, in the sense that they aren’t necessarily at the edge of chaos,
or show an irregular and systematic degree of connectivity. However,
the projects that apparently skip this class were chosen for two
important reasons. They either provide advancement in terms of visual
depiction techniques/methods or show conceptual uniqueness and
originality in the choice of a subject. Nevertheless, all projects have
one trait in common: the whole is always more than the sum of its parts.

How it started

The idea for this endeavor started on my second year MFA program at
Parsons School of Design. During this period I conducted extensive
research on the visualization of complex networks, which culminated
with my thesis project Blogviz: Mapping the dynamics of information diffusion in Blogspace.
One thing I found while exploring this area was the lack of an
integrated and extensive resource on this subject. This is the main
reason why this project came to life.

Later on, as a teaching assistant of Information Architecture at Parsons Design+Technology

program, together with Christopher Kirwan, I was able to consolidate
most of this research as part of an independent study. The key chunk of
projects shown here was gathered during this phase. My ultimate goal is
to keep adding new projects to a still undetermined limit.


What are the demographics of Elkhart Lake, Wisconsin, pop. 1,034?

The
Cartography blog tips us to a valuable site when quick hits are
needed on a community, a SMALL place, in the U.S. or Canada. 
Check out ePodunk

“ePodunk is a site that
focuses on place and provides information on 25,000 communities in the
U. S. The site also contains a number of interesting maps, including
maps of the Katrina diaspora, ethnic origin, fastest growing counties
and others. There is also a Canadian version of the site, focusing on
Canadian places, but it, sadly, does not seem to have any maps.”



Growth opportunity (of the intellectual sort) for journalists
Nov 18th, 2005 by Tom Johnson

With newspapers — and news magazine — cutting staff on
an almost weekly basis, some of us in journalism are going to have to
reinvent ourselves.  One of our tenents of Analytic Journalism is
simulation modeling, a methodology and analytic tool we believe will be
to the social sciences in the 21st century (and journalism IS a social
science) what quantum physics was to the hard sciences in the
20th. So here's an interesting opportunity for someone.

More JAGIS with Google Earth
Nov 16th, 2005 by JTJ

Another nice piece of creativity and innovation comes
along in the Google Earth mashup that depicts not just the U.S.
military deaths in Iraq, but the age and location of those
killed.  This, along with a pop-up of the causality's data, is the
kind of applied JOURNALISM tool university's — and newsrooms — should
be teaching.

Iraq Conflict Casualties Map in Google Earth

In
response to All Saints/Veterans Day, someone decided to collect and
post a memorial of those who gave their lives so far in the Iraq
conflict from the Americans and Coalition Forces. The author is called
'purblind_horus' at the Google Earth Community and he wanted this to be
as non-political as possible. He wanted to remember those who gave
their lives. He is also working to show the even larger number of
innocent Iraqi's who have lost their lives.

Once you download the war casualties file , you will see placemarks showing the locations of the homes of each soldier. The information came from the official icasualties.org
web site, and includes the 2212 casualties through 27-October-2005. In
addition to the home location of each casualty, if you click on the
placemark it may contain a photo, a link to basic background
information, and links to other information, if available, such as news
stories.

This is a valuable, and sobering, effort. It has been greatly
appreciated by many at the GEC, and I hope some find it worthwhile here
at the GEB as well. Here's the original post. Good work 'purblind_horus'!

Who's sitting on local juries in Louisville, Kentucky?
Nov 10th, 2005 by JTJ

A nice bit of AJ done by the folks at the Louisville

, who analyzed the jury pool and composition
in the C-J's home county.  Some good thinking and moderate
statistical-lifting drives the series.

People who live in mainly African-American areas
are less likely to serve than those from mostly white areas, a

Yes, Virginia, methodology DOES matter

A piece on calling the elections in Detroit:


MAKING A FORECAST: A secret formula helps producer call the election right

BY CHRIS CHRISTOFF

FREE PRESS LANSING BUREAU CHIEF

November 10, 2005


What was a viewer to believe?


As polls closed Tuesday, WDIV-TV (Channel 4) declared Freman Hendrix winner of Detroit's mayoral race by 10 percentage points.


WXYZ-TV (Channel 7) showed Hendrix ahead by 4 percentage points, statistically too close to call.


But WJBK-TV (Channel 2) got it right, declaring just after 9 p.m. that
Mayor Kwame Kilpatrick was ahead, 52% to 48%, which turned out to be
almost exactly the final 53%-47% outcome declared many hours later.


And it was vote analyst Tim Kiska who nailed it for WJBK, and for WWJ-AM radio, using counts from 28 of 620 Detroit precincts.


Kiska did it with help from Detroit City Clerk Jackie Currie. She
allowed a crew that Kiska assembled to collect the precinct tallies
shortly after the polls closed at 8 p.m.


Using what he calls a secret formula, Kiska calculated how those 28 precincts would predict the result citywide.


His formula also assumed that absentee voters chose Hendrix over Kilpatrick by a 2-1 ratio.


That's different from the methods of pollsters who got it wrong
Tuesday, Steve Mitchell for WDIV and EPIC/MRA's Ed Sarpolus for WXYZ
and the Free Press. Both men used telephone polls, calling people at
home during the day and evening and asking how they voted.


It's a more standard method of election-day polling, but Tuesday proved treacherous.


Kiska, a former reporter for the Free Press and Detroit News, has done
such election-day predictions since 1974, but said he was nervous
Tuesday.


“Every time I go into one of these, my nightmare is I might get it
wrong,” said Kiska, a WWJ producer. “I had a bad feeling about this
going in. I thought there was going to be a Titanic hitting an iceberg
and hoping it wouldn't be me.”


Kiska said he especially felt sorry for his friend Mitchell.


Mitchell said he's been one of the state's most accurate political
pollsters over 20 years, but said his Tuesday survey of 800 voters
turned out to be a bad sample.


He said polling is inherently risky, and that even well-conducted polls
can be wrong one out of 20 times. “I hit number 20 this time.”


For Sarpolus, it's the second Detroit mayoral race that confounded his
polls. He was the only major pollster in 2001 who indicated Gil Hill
would defeat Kilpatrick.


Sarpolus said the pressure to get poll results on the air quickly made
it impossible to adjust his results as real vote totals were made
public during the late evening.


Of Kiska, Sarpolus said: “You have to give him credit. … But you have to assume all city clerks are willing to cooperate.”

Geocoding and the GISCorps
Nov 10th, 2005 by JTJ

An interesting piece today from CNN on the value of geographers in the hurricane rescuse and recovery business.

See http://edition.cnn.com/2005/TECH/11/10/gis.technology/

'Geocoding' used to locate Katrina survivors

Street addresses not very useful after hurricane hit

By Marsha Walton
CNN

(CNN)
— Police, firefighters, and Coast Guard crews may be the first to come
to mind when naming the lifesavers during disasters such as Hurricane
Katrina.

It might be time to add geographers to that list.

In
the sometimes desperate hours following Katrina's landfall, experts in
geographic information services — GIS — helped search and rescue
crews reach more than 75 stranded survivors in Mississippi.

One
of their most valuable tools was a process called “geocoding,” the
conversion of street addresses into global positioning system (GPS)
coordinates.

With streets flooded, street signs missing, and
rescue crews unfamiliar with the Gulf Coast area, street addresses were
not very useful.

“They would get phone calls, or the Coast Guard
would come in with addresses in their hands and say, 'I need a latitude
and longitude for this address.' So the GIS professionals would do a
geocoding, give it to the Coast Guard who got on helicopters and saved
lives,” said Shoreh Elhami, director of GISCorps.

Elhami,
co-founder of GISCorps, said that since 2004, the organization's
volunteers have responded to disasters such as the Asian tsunami and
Hurricane Katrina, as well as efforts to provide humanitarian relief,
sustainable development, economic development, health, and education in
all parts of the world.

The Corps had 20 volunteers on the ground in Mississippi less than 48 hours after Katrina's landfall.

GISCorps
is part of URISA, the Urban and Regional Information Systems
Association. Elhami said more than 900 qualified volunteers have GIS
experience, and range from from city and state government officials to
academics to people in private industry.

Volunteer Beth McMillan,
a field geologist and professor at the University of Arkansas in Little
Rock, worked in Pearl River County, Mississippi, a couple of weeks
after the storm.

“A couple of days after the hurricane hit, I
felt so down, and wondered what I could do. I could give a little bit
of money, but that doesn't seem very satisfying. To be able to have a
skill that can be used is much more empowering, it doesn't make you
feel so helpless,” said McMillan, back in Little Rock.

Although rescue efforts were over by the time she arrived, there were scores of other tasks she and her colleagues completed.

“We
had laptops and map plotters, and a database that the group from the
first week had put together. One map we produced showed cell phone
towers in the county, and the estimated coverage of those towers.
Everybody was communicating with cell phones and they needed to figure
out where to go within the county to talk to one another,” McMillan
said.

McMillan described the volunteer efforts as a sort of “Maps to Go” for a wide range of people needing immediate information.

Their
maps detailed road conditions, power outages, underground gas storage,
and facilities with hazardous materials. Agencies from FEMA to the Red
Cross to local utilities relied on the information that they constantly
updated.

“This is how technology can make a difference,” said
David Shaw, director of the GeoResources Institute at Mississippi State
University.

“It was a great team effort,” said Shaw, for a crisis that he said had deteriorated into a Third World situation.

Shaw
said he was amazed at the talent and the creativity of, basically, a
roomful of strangers at these county Emergency Operations Centers.
While eventually satellite links and Internet connections made the
tasks easier, in some cases large amounts of data had to be driven
several hours from one site to another.

Volunteers are never sure
of the conditions they might face when deployed to disaster sites or
developing countries. Assignments usually last between two weeks and
two months. McMillan said her many experiences “roughing it” as a field
geologist helped her deal with the living conditions in Mississippi.

“They
said be prepared for really hot weather, and bring a sleeping bag,” she
said. “I slept in an empty U.S. Department of Agriculture building on a
cot, with probably several hundred other people. But it did have power,
bathrooms, and showers, so conditions were not as bad as they could
have been,” she said.

She and her colleagues ate MREs (military meals ready to eat) and worked 12-plus hour days every day.

“We
did get a chance to tag along one afternoon with a couple of National
Guardsmen from Mississippi on a trip to the coast. That was one of the
most memorable experiences of my life. I've never seen such
destruction, and the only way to really understand it is to see it in
person,” she said.

Various "populations" of a city
Nov 9th, 2005 by JTJ

A city never sleeps?  Well, some do, at least according to a fairly recent report from the Census Bureau. 


Census Bureau Releases First-Ever Data On Daytime Populations for Cities and Counties

October 21, 2005

Company: U.S. Census Bureau
Industry: Demographic Data
Location: Washington, DC, United States of America


If it seems a little crowded on weekdays in cities like Washington,
D.C.; Irvine, Calif.; Salt Lake City, Utah; or Orlando, Fla.; it's not
your imagination. Among cities with 100,000 or more people, these four
show the highest percentage increases in population during the day as
opposed to their resident population.


The findings come from the first-ever U.S. Census Bureau estimates of
the daytime population for all counties and more than 6,400 places
across the country, based on Census 2000 data.

The concept of the daytime population refers to the number of
people, including workers, who are present in an area during normal
business hours, in contrast to the resident population present during
the evening and nighttime hours.


“Information on the expansion or contraction experienced by different
communities between nighttime and daytime is important for many
planning purposes, including those dealing with transportation and
disaster relief operations,” said Census Bureau Director Louis
Kincannon. “By providing information on the number of people not living
in the area, but nevertheless greatly affected by the event, the data
can provide a clearer picture of the effects of disasters such as
Hurricanes Katrina and Rita.”


The places where the largest percent increases in daytime over
nighttime populations occur tend to be those with small resident
populations. For example, among medium-sized cities, Greenville, S.C.,
has a daytime population that is 97 percent higher than its nighttime
population. Palo Alto, Calif., increases by about 81 percent, and Troy,
Mich., by 79 percent. Among very small places, gains approached 300
percent in Tysons Corner, Va. (292 percent); and El Segundo, Calif.
(288 percent).


Other highlights:

  • New York City has the largest estimated daytime population, at more
    than 8.5 million persons. The increase of more than half a million
    people over the nighttime population is bigger than that found in any
    other area. However, the 7 percent increase puts New York in the middle
    of the pack on percentage change among cities with more than a million
    residents.
  • The second highest numeric daytime increase is in Washington,
    D.C., where 410,000 workers boost the capital's population by 72
    percent during normal business hours.
  • Other big cities with large daytime gains are Atlanta (62
    percent), Tampa (48 percent) and Pittsburgh and Boston (both around 41
    percent).
  • Typical examples of sizable expansion of daytime populations
    in small cities can be found in places such as Paramus, N.J.; Redmond,
    Wash.; and Beverly Hills, Calif., among others.
  • About 250,000 people worked in New Orleans prior to Hurricane
    Katrina. Almost 150,000 of these workers were residents of New Orleans,
    but the remaining 100,000 lived outside the city.
  • One of the most extreme examples of daytime population
    increase is Lake Buena Vista, Fla., which has almost no permanent
    residents but swells to an employment center of more than 30,000 people
    during the day.

  • Additional tables are available on the Census Bureau's Internet
    site
    at . Choose the “Subjects A to Z” link at the top of the page,
    click on the letter “D” and then select the link to “Daytime
    Population.”
