Update on GIS information for Haiti

January 20, 2010 / / 0 Comments

We all woke up this morning to see news that another earthquake has happened in Haiti, near the center of the first one eight days ago.

“The United Nations Development Programme (UNDP) employed nearly 400 Haitians in cash-for-work activities to jump start the local economy and facilitate the delivery of urgently needed humanitarian assistance.”

This post is an update to my previous article about how GIS is used for disaster relief efforts. I recently came across a webpage on Harvard’s China Earthquake Geospatial Research Portal that lists copious, up-to-date, GIS-compatible data from organizations around the world. The portal began in response to the Sichuan, China, earthquake in May 2008.

Visit the Haiti GIS Data Portal now.

For new GIS students, this would be a great starting point for a class final project. The Portal is hosting the datasets as a public service and invites anyone with relevant data to submit it to the site operators for wider dissemination. Data comes from the United Nations, several universities, OpenStreetMap contributors, and the German Center for Air and Space Travel, among others.

Coast Guard and Navy helicopters airlifted injured Haitians to a private hospital in Milot, Haiti. U.S. Coast Guard photo by Petty Officer 3rd Class Brandyn Hill.”

As I mentioned in the previous post, there are many photos on Flickr when you search for “haiti earthquake.” When I wrote the post on January 14, 2010, there were only about 300 photos, and now there are over 6,900. Only 1,200 have a Creative Commons license, though (both of the photos above have a Creative Commons license). It seems that the United States Military, the United Nations, and major relief organizations are providing the majority of photos. And they’re uploading them fast. The number of photos on Flickr jumped by 50 from when I started this paragraph.

Two new skyscrapers in River North

January 20, 2010 / / 0 Comments

Both of those steel and glass skyscrapers opened in 2009.

On the left (westernmost) is 300 N LaSalle Street. The official website says the building is pre-certified for LEED. This really means someone looked at the design specs and said it means certification. But designs change and I can’t yet find this project on the U.S. Green Building Council’s Certified Projects list.

On the right (easternmost) is 353 N Clark Street. The developer, South Parcel Development, sought LEED Silver certification for Core & Shell but received one better: Gold.

How GIS helps earthquake relief efforts for Haiti

January 14, 2010 / / 0 Comments

While Geographic Information systems software can definitely produce pretty maps, its power lies in analyzing data and plotting or comparing sensory or observed data to spatial data (like roads or terrain). The earthquake in Haiti rocked the capital city, Port-au-Prince with a shock of magnitude 7.0 on Tuesday, January 12, 2010.

A photo from a United States military flyover shows damage in the Port of Port-au-Prince, Haiti. Photo taken by Petty Officer 2nd Class Sondra-Kay Kneen and uploaded by Chuck Simmins.

There are several applications for GIS to help with earthquake response, and two blog posts that appeared this morning shed light on how.

The first article came from ESRI, the California-based makers of ArcGIS, the most used GIS application. The article linked to a user-built map on their ArcGIS Online service showing on Bing maps where the earthquake and its aftershocks struck (the map sits behind a registration wall). ESRI even has a disaster response team that helps organizations get their response projects off the ground quickly.

Infrastructurist posted the second article, showing some before and after satellite imagery of Haiti, provided by Google and GeoEye.

So what can GIS do? From ESRI’s list, “GIS for Disaster Response“:

  • Rapid identification of potential shelter/housing locations (schools, libraries, churches, public buildings) appropriate for supporting affected populations.
  • Determine how many tents will be needed based on the location of populations affected by the disaster.
  • Analyze areas where large numbers of refugees can establish camps out of harm’s way that are accessible for supply delivery and have access to water and other resources necessary to support large numbers of people.
  • Many more examples.

Google snaps up another open web advocate

January 13, 2010 / / 0 Comments

I’ve been following the work of Chris Messina (also known by his handle, factoryjoe) for a couple years now. I can’t remember how I found him (maybe it was BarCamp, OpenID, of the Firefox ad), but I know why I follow him. Like me, he wants to keep the web open and data transferrable or transportable.

While browsing the New York Times Technology section Monday morning (my favorite tech news site, hands down), I saw the headline that he now works for Google (Monday was the first day). This kind of shocked me. I feel Google gets a little scarier every week: some of my friends have admitted that a lot of their online life exists on Google servers and feel queasy about what could happen (some call this “the cloud” and have pointed out the devastating possibilities for privacy and business).

The author pointed out Messina’s history in open web advocacy (he hijacked his high school’s website because of its refusal to allow an ad for a new gay/straight alliance). The article offers some speculative reasons why Messina made the move, but I want to discuss the inclusion of a quote from Eran Hammer-Lahav, who works for Yahoo!.

With Messina, Smarr, [inventor of OpenID and more Brad] Fitzpatrick and others all working for Google, focusing on the Social Web, there is less and less incentive for Google to reach out. Google has a strong coding culture which puts running code ahead of consensus and collaboration. Now with so many bright minds in house, they are even less likely to reach out. Quote continues…

In other words, with all of the open web advocates being Open Web Advocates (Messina’s new title), who will advocate for web users now? There’s me, for sure. And there are folks standing behind Open Government and Government 2.0. People like Barack Obama (he issued the Transparency and Open Government memo), Adriel Hampton (host of Gov 2.0 Radio podcast), Mark Abraham (urbandata on Twitter), and anyone in the government “black box” who’s willing to set government data free.

In addition, new websites are up and running that remix and mash up government data into useful applications that can promote, through the web, a different level of ownership of one’s community. Or websites that provide useful and relevant information for residents. Websites like SeeClickFix (identify problems in your neighborhood to get city politicians and staff to take notice), or the Center for Neighborhood Technology’s Housing and Transportation Affordability Index.

And don’t forget that the Chicago Bicycle Parking Program liberated its bike parking data into Excel, KML, and GIS-compatible formats in 2009.
