a large-scale news paper analysis system that is able to create “entity datamaps”, a spatial visualization of the interest in a given named entity. the aim of this system is to identify entities which display regional biases, by estimating the frequency of reference of an entity in any given city.
entities likely to be geographically-biased include United States cities & local sports teams. entities likely to have little bias include foreign cities, country names, & national political figures. The text is acquired from about 800 US online newspaper sources.

We're not wild about using “image” as a verb, but the conference looks promising and certainly appropriate for those journalists who understand that we have to learn to tell stories with more than just words and pictures. Yup, “HCI” is where it's at, or where it's going to be at.
Imaging the City:
Recent technological developments mark the city as a central and perhaps special space for human-computer interaction research and practice. Visions of ubiquitous computing, the resonance of the ‘urban probe’, and the proliferation of interactive mapping services speak to the significance of the urban landscape to studies of Human-Computer Interaction. But such visions and technologies require, produce and reproduce images of urban space that influence what these systems, and our interactions with them, are and might be. Developing and employing technologies for the urban environment requires visualization techniques that both reflect and challenge how we image, and consequently imagine, the city.
The Rrove blog — no, no, not THAT Rove (different spelling) — delivers a round-up review of nine sites related to community mapping tools. See http://www.rrove.com/blog/2006/12/04/9-awesome-community-mapping-websites/
Disclosure: Rrove.com plays in the community mapping space. This post aims to highlight the innovations and the usefulness that others have made in this game. We haven’t added ourselves to this list – if you want to know more about Rrove, click here.
A community mapping website, in our definition, is a service that gets its members to map and define places. Through crowd-sourcing, these sites are building a database/directory of local and nearby locations that their users can discover and visit. Why is this important? We all know that search advertising is the fastest growing industry in the Internet. Within that market, local search is the up-and-comer. In the next few years, it will be the largest segment within search!
It’s refreshing to see how others have approached community mapping. Some have focused on map creation while others do it through mobile apps. More than that, some players have mapped the community of users to map the physical community (i.e. neighborhoods). Here’s how nine websites (all free) are doing it, what makes them awesome and how you can use their services in your Internet life.
It was the second year of the national crime mapping conference when we realized that, hey, there's a lot of not-just-good-but-great analytic work going in the then-young profession of crime analysis. Seven years later, it's just getting more impressive.
If you can only get to one national conference a year (we assume you're already going to the NICAR meetings), do this one every other year and the Special Libraries Association convention on the off year. NOTE: NO NO NO registration fee!
Registration for the Ninth Crime Mapping Research Conference has opened. This year, there will be no conference registration fees but registration is still required. Preliminary conference details available on the MAPS website: http://www.ojp.usdoj.gov/nij/maps/pittsburgh2007/index.html
The Ninth Crime Mapping Research Conference will take place March 28-31, 2007 at the Omni William Penn Hotel in downtown Pittsburgh, Pennsylvania.
Agenda:
The conference will include a full compliment of workshops, panels and plenary sessions. The main plenary session is entitled GPS in a Crime Analysis Context- Practitioner Consideration, Research Needs.” Panel session topics will include uses of spatial data analysis and GIS in corrections, parole, and probation, geography and crime, geographic profiling, offender travel behavior, NIBRS/incident-based data and mapping, international programs, impact of Hurricane Katrina on crime, crime analysis, spatial data analysis, policing issues, managing sex offenders, travel demand modeling, and more. The conference also includes a map competition, and provides an excellent opportunity for researches and practitioners to network with each other.
The folks at Faneuil Media, a company that “helps site owners publish maps and data, just announced a promising tool, “Atlas.” Check it out because they say….
When I first switched from the newsroom to the web newsroom, I was surprised by all the technical constraints.
As a reporter and editor I had all the tools I needed – it was up to me to create something fit for the front page. As a web editor, content management systems and development priorities became constraints on my ability to publish the news.
With the hope of helping publishers chip away at these constraint, we’re releasing a new mapping tool today. Meet Atlas: www.fmatlas.com.
Atlas is a simple web application that allows you to put Google Maps into your stories in a few seconds.
Certainly there are already mapping tools out there. Atlas distinguishes itself in two ways:
First, it is simple: Point. Click. Map. No messy code, no unnecessary hoops to jump through.
Second, Atlas is designed for news sites. We’re building it so that reporters, editors, producers and local bloggers have an easy way to add maps to their stories.
This first release of Atlas has a very basic list of features. You can:
There’s lots more we want to add, but before going any further, we want to get your feedback. So, try it out, let us know what works, what doesn’t and what we should add.
Thanks to Gary Price at ResourceShelf Newsletter <http://www.resourceshelf.com> for this:
Fifteen cities already are searchable online. Microsoft will drop ads into the maps on computer-generated billboards. You'll be able to type “Starbucks (nasdaq: SBUX – news – people )” on your mobile while standing in San Francisco's Union Square and get a 3-D map guiding you to the nearest one. Microsoft acquired some of this technology in May when it bought videogame ad-broker Massive Entertainment.
While we keep looking at the mapping, we need to remember that the money comes from the advertising, not the mapping per se.
Friend and mega-librarian Marylain Block's “Neat New Stuff” column (http://marylaine.com/neatnew.html) points us to another example of a great community-building tool. She writes:
A former student of colleague Steve Ross sends this interesting report on how simulation models can/are being used in the real world:
I’m the communications officer for the International Research Institute for Climate and Society at Columbia University. The IRI specializes in making forecasts of climate for every part of the world by using data from satellites, meteorological stations and proxy records (tree rings, corals, etc) to run models. The models tell us, with varying degrees of certainty, how much off the “norm” rainfall, temperature and humidity will be for a given place in the world. We’re not so much interested in long-term climate change (global warming, sea level rise, etc) as we are in season-to-season changes (e.g. monsoonal patterns, drought, flooding, etc.). And the IRI isn’t a purely academic institution — its main objective is to use the forecasts and climate monitoring to develop and undertake projects that mitigate the effects of climate change in developing countries. We never do this alone: all of our efforts are in collaboration with scientists, policymakers and NGOs in these countries.
Here’s a brief description of some projects we’re currently working on:
*Climate and malaria:* The IRI collects an enormous amount of temperature, rainfall and humidity data for southern Africa. As it it turns out, the presence or absence of malaria in a given region depends strongly on these three climate factors, so scientists here developed a mapping tool that shows the risk of a malaria epidemic for every month of the year in every part of sub-Saharan Africa. We train health workers from countries in this area on how to use the information to adequately prepare for epidemics. (see /http://tinyurl.com/yxzp7t/ )
*Climate and fire-management* Fires in Indonesia damage unique and delicate ecosystems, increase carbon dioxide emissions, and produce noxious smoke and haze that leads to thousands of hospitalizations every year. Since the intensity and duration of these fires depend on the amount of rainfall the region receives every season, the IRI is using its rainfall forecasts to develop an early-warning system that policymakers and NGOs can use for planning purposes. For example, if our models tell us there is a strong chance of drought conditions in the next 3-month period there, our Indonesian partners can take specific actions, such as conserving irrigation water so that the fields where these fires occur aren’t drained completely and therefore aren’t as susceptible to burning. (see /http://tinyurl.com/yjehn6/)
*Index-based weather insurance for farmers*The IRI and the Commodity Risk Management Group at the World Bank are involved in a project to develop insurance contracts that protect Malawi farmers against periodic, crop-destroying droughts. Traditionally, farmers would take out loans to buy seeds at the start of every season. If a drought occurred, the farmers’ crops would die, and they wouldn’t be able to pay back the banks. But under this new program the farmers can purchase an insurance (a very small percentage of the price of the seeds) against crop loss when they buy seeds. If a drought occurs, the farmers get a full or partial payout and can use the money to repay their loans. IRI’s role in this is to use its weather monitoring data for the region to help the local insurance companies develop reliable contracts. The fascinating aspect of this program is that it is completely subsidized by the farmers. (no link available yet)
My role in all this is to make these and other projects known to the public at large. Many of you receiving this email are journalists of one species or another. If you are developing stories or graphics that have to do with climate or earth science, think of me. I’ll put you in touch with experts or send you bucketfuls of GIS and other data.

Mike Stucka stucka@whitedoggies.com today provided a rich set of links during a discussion of mapping on NICAR-L. If you're interested in Minard's map/chart/info graphic of Napeoleon's march to Russia — and especially if you use it as a teaching tool — check out the links below.
Click here to see the SAS code (zoomed-in view)Charles Minard is a famous map-creator from the late 1800's.Perhaps his most famous map is the following showing Napoleon's March on Moscow in 1812.I looked at several other people's version of Minard's map on the following webpage and devised an idea for my own version, using SAS/Graph's "proc gmap".I used longitude/latitude, troop number, and city data from the following webpagein combination with the temperature data from the following translation of Minard's Map.I'm somewhat "geographically challenged" when it comes to europe, especiallywith the city names on the Minard map (and I'm probalby not alone?) Therefore I decided to plot Napoleon's path on *modern* maps, with thecountry names labeled. Also, I wanted to give a "50,000-mile" view ofthe map, so people could see where this area was in relation to otherareas of europe (such as France).******************************************************************* Here's my 50,000-mile map.** Which drills-down to this Zoomed-in map.** Here is the SAS code used to generate the maps.*****************************************************************Here are some details about how I created my map(s) in SAS/Graph...For both of these maps, I used a combination of the sas maps.europe and maps.asia as the base map. I created custom/subsetted/clippedversions of these maps using SAS' "proc gproject", and specifyingthe latmax/latmin/longmax/longmin for the area I wanted in my map.To get the blue ocean/sea water to appear only in the map area I usean annotated rectangular polygon with corners at the exact samelong/lat coordinates as the corners of my map, and annotate it 'behind' the map. (If I had used "goptions cback=blue" that wouldhave filled the entire background of the page with blue, not justthe wanter area in the map.)In the 50,000-mile map, I annotate country names at long/latpositions of my choosing, and I annotate a dashed-line box aroundthe area that will be shown for the drilldown. In this dashed-boxarea, I use annotate's "html" variable to encode a drilldown, so that when you click inside this rectangle it drills-down to the zoomed-in map. I also annotate a dot at the city locations (andI annotate city labels in the zoomed-in map).I use the same technique in both maps to show Napoleon's path.I take the long/lat values, and use them as vertices for a line,and connect the dots with line segments (using annotate move/drawfunctions). The size/width of the line is calculated based on the number of troops (ie, men) still alive during that leg of the trip.One problem with this technique was that it produced big/jaggedgaps/transitions at the line vertices (especially where the lineschanged directions sharply). To smoothe this out, I annotated a 'pie' (filled circle) at each vertex, with the diameter of the pie being the same as the width of the line. With this annotation(as with most all of the lat/long-based annotation in this map)I combine the annotation with the map, use "proc gproject" to dothe map projection, and then separate the annotate from the map(this guarantees that things line up in the correct position).On the zoomed-in map, notice that when you hover your mouse over the city names, you see the city name (and additional info, if available)for that city. If you click on the city names, that launches a google search for information about that city (including the words'Napoleon' and '1812' in the search).When you hover your mouse over the vertex points of Napoleon's path,you'll get a html charttip/flyover-text showing the number of troopsat that point during the march. At first I made these hotspots theexact same size as the visual vertex dots, but the small ones were too small -- therfore I annotate a larger dot 'behind' the map for each vertex, and the charttip is based on the size of those 'invisible'vertex points :)Surprisingly the toughest part of the map was the temperature plot.After trying a few different approaches, I decided to base the positionof the temperature dots and the axes & gridlines & labels all using long/lat coordinates. The distance from the minimum gridline to themaximum gridline is 1 degree of latitude (not to be confused with degrees celcius or degrees farenheit! ;). And for the horizontal positions, I use he position of the cities/battles corresponding tothe temperatures. I color the temperature dots an 'ice cold' lightblue, since they represent cold temperatures./* Written by Robert Allison (Robert.Allison@sas.com) */
