State GIS officers
Oct 5th, 2006 by JTJ

David Herzog posts this good tip to the NICAR-L list:

For those of you who are itching to know what your state's GIS officials
are doing this week in Little Rock, you can visit the National States
GIS Council conference blog at http://www.nsgic.org/blog.

If you're doing GIS and you're not familiar with this organization, you
should check them out. Its members include the top GIS professionals in
your state. These same people help decide how accessible GIS data is in
your state, and how much it should cost. Its main Web site is

Amazon deep sixes A9
Oct 3rd, 2006 by JTJ


From All Points Blog.  Read down into the original posting to see speculation as to why.  Perhaps “user mapping fatigue”?

Amazon Drops Mapping and BlockView and…


Gary at ResourceShelf let me know that Amazon's A9 has dropped mapping and other services this week.

The company “What's New” page says little about why, just that the goodies are gone.

We have discontinued the A9 Instant Reward program, and the
A9 Toolbar and personalized services such as history, bookmarks, and
diary. To get help uninstalling your A9 Toolbar, visit toolbar.a9.com.
We have also discontinued A9 Maps and the A9 Yellow Pages (including
BlockView™).



All (Digital) Power to the People
Oct 2nd, 2006 by JTJ

One of the major aspects of the Digital Revolution that has long intrigued us is how it is driving a shift in power away from institutions and people of traditional authortiy to the individual. 

A great example of how this is happening was reported in today's (1 Oct. 2006) NYTimes.  “A Town’s Architectural Shift, Chronicled Online” was started by Montclair, New Jersey resident Liz George.  She is  managing editor of Baristanet, a community Web site and forum, added an
interactive map to the site to keep a record of teardowns in her town.  The NYT reports:

“On Sept. 22, the Web site started a new feature to chart the town’s
changing architectural landscape — an interactive map that shows
teardowns, homes with historic designations and recent construction.

“'Maybe
something like this will give people pause,' said Ms. George, 39, in
her office at her gracious 100-year-old home. 'Knowing you’re having
your house on the teardown map, knowing it will be part of this trend,
I don’t think it has a positive implication.'

'The teardown
issue has taken on a sense of urgency here after a developer bought the
blue-shuttered Colonial-style house, on North Mountain Avenue, for
$870,000 last fall and demolished it this summer with plans to build
six town homes. The action led town officials to rezone about 200 lots
— including the North Mountain Avenue property — from a designation
that allows up to eight units on a single lot to a designation that
allows only two. The developer has since dropped his plans and has put
the empty lot up for sale.

Of course, a newspaper could have done the same thing, but so far as we know, none has.  So the least the industry could do is supply the software apps, and maybe some instruction, to let citizens build their local databases.




Mapping DWI crashes
Sep 21st, 2006 by Tom Johnson

A interesting mapping project today from Abuquerque's DWI Resource Center.  A map showing a surprising clustering of the city's DWI-related events.  Wouldn't it again be an interesting reporting tool — and a draw for readers — if a newspaper were to create a dynamic and regularly updated map of this sort for its market area?

Bernalillo County (New Mexico) DWI Crash Map
http://www.dwiresourcecenter.org/crashmap.shtml


The Bernalillo County DWI Crash Map is a new tool to help citizens
avoid drunk drivers by assisting them in locating the more dangerous
roadways
in and around Albuquerque and allowing them to plan alterative
commuting routes and times. The DWI Crash Map indicates locations
around the county
with the highest incidents of alcohol-related crashes, and the areas in
the county with the highest concentrations of alcohol establishments.
The map
also contains charts showing alcohol-related crashes and DWI arrests by
time of day.

Although a citizen's best defense against a drunk driver is to
always wear a seat-belt and drive defensively, this map can assist you
in
planning your daily commute to avoid high-risk intersections and times
of day when alcohol-related crashes are most likely to occur.

To view the map, you will a need free copy of Adobe Acrobat Reader.

Major Crime Mapping Conference (2007) Call for Papers
Sep 20th, 2006 by Tom Johnson

Eight or nine years back we attended one of the first Crime Mapping conferences sponsored by the National Institute of Justice and found it to be one of the most creative and practical events of this type.  (We also have very high regard for the ESRI Users Conference and the Special Libraries Assoc. meetings.)  So we want to be sure to let all analytic journos know about next year's Crime Mapping confab, scheduled for March 28 to 31, 2007 in Pittsburg, Penn.  Here's part of the official call for papers:

The Mapping & Analysis for Public Safety Program announces it's Call 
for Papers for the Ninth Crime Mapping Research Conference in Pittsburgh,
PA at the Omni William Penn Hotel, March 28 to 31, 2007. The deadline
for submission is Friday, September 29th....

The theme of this conference will be Spatial Approaches to
Understanding Crime & Demographics. The use of Geographic Information Systems
(GIS) and spatial data analysis techniques have become prominent tools for
analyzing criminal behavior and the impacts of the criminal justice
system on society. Classical and spatial statistics have been merged to
form more comprehensive approaches in understanding social problems
from research and practical standpoints. These methods allow for the
measurement of proximity effects on places by neighboring areas that lead
to a multi-dimensional and less static understanding of factors that
contribute to or repel crime across space.

The 9th Crime Mapping Research Conference will be about demonstrating
the use and development of methodologies for practitioners and
researchers. The MAPS Program is anticipating the selection of key accepted
presentations for further development of an electronic monograph on GIS,
Spatial Data Analysis and the Study of Crime in the following year. Its
purpose will be to demonstrate the fusing of classical and spatial
analysis techniques to enhance policy decisions. Methods should not be
limited to the use of classical and spatial statistics but also
demonstrate the unique capabilities of GIS in preparing, categorizing and
visualization data for analysis....





Watching the ebb and flow on city streets
Sep 6th, 2006 by Tom Johnson

Friend Steve Guerin tips us to “Cabspotting,” a fascinating site created by San Francisco's Exploratorium.  It's about georgraphy, traffic flow, and complexity.  Give a look to “Cabspotting”

About Cabspotting

Cabspotting
traces San Francisco's taxi cabs as they travel throughout the Bay
Area. The patterns traced by each cab create a living and
always-changing map of city life. This map hints at economic, social,
and cultural trends that are otherwise invisible. The Exploratorium has
invited artists and researchers to use this information to reveal these
“Invisible Dynamics.”

The core of this project is the Cab Tracker.
The Tracker averages the last four hours of cab routes into a ghostly
image, and then draws the routes of ten in-progress cab rides over it.

The Time Lapse
area of the project reveals time-varying patterns such as rush hour,
traffic jams, holidays and unusual events. New projects are produced by
the Exploratorium's visiting artists and also created by the larger
Cabspotting community.



Something cool for the Excel day-trippers

OK, OK.  Maybe we've crossed over some line social acceptability, but this is neat addition to the analytic journalist's toolbox.  My friend Mike Collins tips us off to:

Lightweight data exploration in Excel

,

Lifehacker, delicious folks! This post generated a ton of great community ideas. Check out our followup post to see some more ideas and to download a spreadsheet with demos. Thanks.

We often are given a chunk of data in Excel that we need to explore.
Of course, the first tool you should pull out of your toolbox in cases
like this is the trusty PivotTable (it slices, it dices!). But at times
we have to dig a little deeper into the toolbox and pull out the
in-cell bar chart. Here’s what it looks like.

In cell bar charts in Excel

This picture shows some Major League Baseball data. I’m graphing the
number of walks each player has taken. The bar graphs are built using
the Excel REPT function which lets you repeat text a certain number of
times. REPT looks like this:

=REPT(text,number_of_times)

For instance, REPT(”X”,10) gives you “XXXXXXXXXX”. REPT can also
repeat a phrase; REPT(”Oh my goodness! “,3) gives “Oh my goodness! Oh
my goodness! Oh my goodness! ” (my daughter’s an Annie fan).

For in-cell bar charts, the trick is to repeat a single bar “|”.
When formatted in 8 point Arial font, single bars look like bar graphs.
Here’s the formula behind the bars:

The formula behind the bar

What are some practical uses of in-cell bar graphs? For starters,
they offer a good way to profile a dataset that has hundreds or
thousands of rows. Here’s a picture of in-cell bars compared to a
standard excel bar graph for a dataset with about 500 rows. It can be a
lot easier to scan the results when they’re in-cell.

Another usage is lightweight dashboards. The report below compares a
number of metrics for players using both in-cell bar graphs as well as
conditional formatting. The conditional formatting highlights the top
25% of each metric in green and the bottom 25% in red but that is a
story for another day.

Statistically correct maps
Jul 6th, 2006 by JTJ

This week Mark Hartnett, of the Palm Beach Post, alerts us to a map he and his paper recently published, a map of the hometowns of the U.S. troops killed as a result of the U.S. invasion of Iraq and Afganistan.  They did a similar map a year ago, but one that reflected the gross numbers of the dead from each city.  This year they put those numbers in context by displaying the rate of deaths per 100,000 population.  It makes a difference and raises new questions.  Note that the height of the columns reflects, as Mark Hartnett points out in his comment below, the number of deaths while the color indicates deaths-per-100,000 residents ages 18-64.


To see the map, go to “2,800 Hero's Hometowns.”  (Yes, they are all worthy men and women, but “heros”?)  [Here's the link to the story. ] 





Blazing "Human Trails In Cyberspace"
Jun 30th, 2006 by JTJ

From The Chronicle of Higher Education:

“Human Trails In Cyberspace

Social scientists create maps of online interactions

Blogs

Multimedia: Maps and audio charting human interactions in cyberspace

If the Internet is a new kind of social space, what does it look like?

That's a question of particular interest to social scientists eager
to see what cyberspace might reveal about the nature of human behavior.

Researchers, after all, have long sought to map social groupings and
interactions in the physical world. Now, with so much activity on
computer networks, scientists can collect vast amounts of hard data on
human behavior. Each blog points to other blogs in ways that reveal
patterns of influence. Online chats can be tallied and parsed. Even the
act of clicking on links can leave trails of activity like footprints
in the sand….
