There’s an app for that – citizen pothole reporting

This week,  a smartphone app will be made available to the citizens in Longview, Texas, where pictures and video can help the city address issues such as potholes that need repairing. Starting yesterday, citizens could log on to their smartphones, take a photo or video of a pothole or other problem in the city, note location and send it to the city.

John Snow’s 1854 Cholera Map comes to life with the CartoDB platform

Thursday, February 9th, 2012

John Snow created a map of a cholera outbreak in the district of Soho, London in 1854, which helped to convince authorities that the disease was caused by water ( in particular, it originated from one pump in Broad Street). The CartoDB platform allows you to map data and develop location aware applications very easily. This example of John Snow’s Cholera Map of London presented with CartoDB demonstrates how CartoDB can quickly combine different data types, then display them on a map.


Going where no GPS has gone before

Monday, November 21st, 2011

In November a gathering of 150 GPS engineers convened in Stanford at the Stanford Linear Accelerator Center to discuss the $110 billion GPS market for military and commercial aviation systems, consumer mapping services in cars and automated agricultural machines, among other related industries at the fifth annual Stanford University symposium on Position, Navigation and Time.

A big topic on the table is that GPS is no longer the only navigation and tracking system on the planet any more. According to a November article in Wired, there are four things threatening the future of GPS:

  • Next-generation mobile broadband services angling for a piece of the electromagnetic spectrum relied upon by GPS
  • Cheap GPS jammers flooding the highways, thanks to consumers worried about invasive police and employers surveillance;
  • Cosmic events, like solar storms
  • Future location technology that will ultimately push those services to places where GPS hasn’t been able to go.

What’s on the horizon is the new mobile broadband company, Lightsquared, that has been said to threaten GPS signals with interference from a neighboring spectrum. Lightsquared appears at first like it will solve a lot of problems to broadband, by offering cable – like bandwidth to mobile customers through LTE, a next generation wireless service. What’s more, the Obama administration has endorsed Lightsquared – which resides in the same spectrum that runs GPS, which is lower power and gets interference easily.


Search engines and social media tracking

Monday, October 31st, 2011

Last week I read the Wired Cloudline blog Beyond Google’s Reach: Tracking the Global Uprising in Real Time which talked about the search engine Topsy, which is designed to “rank people, not pages,” as Google does. Topsy is an entirely different search engine model than Google, and therefore can pick up and aggregate information from social media in perhaps a different way than Google.

A case was made that suggested that Google did not pick up tweets on the October 15th protest at Occupy Wall Street as efficiently as Topsy.

I decided to look for myself and compare the posts that have been gathered today for both Google and Topsy for Occupy Wall Street. What is interesting is that each are picking up different bits of media –

Topics for Google:
Google is picking up newspaper articles and newscasts, such as “Opinion: Occupy Wall Street is a vigil, not a protest,” New Jersey Star-Ledger, “Occupy Wall Street kitchen slowdown targets squatters,”, “Occupy Wall Street in the Age of Technology”, Huffington Post, “Most Americans Aren’t Occupy Wall Street’s ’99 Percent’ The Atlantic.

Topsy has picked up the following topics in tweets: “Protesters turn their back on @ericcantor during speech at University of Michigan #ows ”
A trustworthy #OWS activist tells me that an influx of homeless and hardened criminals is causing major issues for Zuccotti campers
“Police use bulldozers to break up @OccupyRichmond. #ows ”
“#OWS has spread to 87 countries with 1,039+ distinct events. (and counting) ”

Note that the Google search is producing articles that were published as much as three weeks ago, while the Topsy search is displaying tweets written just 18 minutes ago.

In the realm of tracking events of local or global importance, it would seem that a combination of these two types of searches would be best, so that we have well researched articles side by side with the up-to-the-minute crowdsourced view of the bystander.

On the one hand, in-depth reporting of a body of knowledge on an event is always useful in tracking history and trends, and offering insightful perspectives. What is published in newspapers, magazines and books is thought to have staying power, whereas we are not yet sure how long the impact of a tweet or Facebook post will last.

The veracity of tweets is questionable, and they are posted before anyone has a chance to check whether they come from reliable sources. When several sources convey the same message, however, it can indicate that something is really happening at a given location. Topsy can be important in tracking social movement such as the progress of an uprising or movement of a group of people. There is power in numbers, so the sheer number of people who will protest now using social media may increase because they have more confidence in doing so when they know others are of like mind.

Filters for the social web

Monday, April 25th, 2011

These days, very often citizen reporting of dramatic events is being relied upon from sources such as Twitter, blogs, and cell phone photos and reports. The amount of information can be daunting to those needing to report on events or assemble a big picture.

Storify, based in San Francisco, is one of several Web start-ups — including Storyful, Tumblr and Color — that are developing ways to help journalists and others sift through the explosion of online content and publish the most relevant information.

ABI Research report says Wi-Fi location will overshadow all other location technologies

Tuesday, December 14th, 2010

From ABI Research comes the prediction that Wi-Fi location will “outstrip
 all other location technologies including GPS, cellular and MEMs, with shipments reaching more than 1 billion by 2015. ”

Senior analyst Patrick Connolly comments: “Location-based services, revenues and advertising are the hot topics of 2010 as companies grapple to gain control of this market. The key is accurate, ubiquitous location-finding across a variety of portable devices such as mobile phones, tablets and laptops. ABI Research has forecast that with the proliferation of Wi-Fi and increasingly lower cost or free location engines, it will become the most widely available location technology over the next five years.”

I’m dreaming of a Twitter Christmas

Monday, November 30th, 2009

According to the New York Times, “America’s first Twitter Christmas got under way in earnest on Friday. Across the land, retailers and their customers used the social networking site to talk to one another about bargains, problems, purchases and shopping strategies.”

The article gave an example of a woman who had bought a navigation system that didn’t work. She sent a tweet to Best Buy’s Twitter account and within minutes, they had customer support helping her with the problem. Customers also reported useful information on what parking lots in what malls were full, with advice on where it was best to park to get to certain store locations.

I went to Twitter to check this out. Most of Twitter regarding retail was devoted to trivial comments such as, “I got this great sweater at…”

Retailers’ messages are viewed by Twitter users who “follow” the retailer, basically this means the retailer’s posts show up on their Twitter home page when they log in.

This may be useful for Cyber Monday shoppers.
