If San Francisco Crime were Elevation | Doug McCune - 0 views

  • Really nice. Be great to see the two combined – heatmaps and topography or atleast some kind of colour banding added to the topography. That would open up all kinds of possibilities – you could slice horizontally along the bands and create layers of different ranges. In fact mixing colour and topography would also give you a way of showing two sets of data concurrently – topography for prostitution and some kind of colour banding for wealth for example.
  • Makes the numbers come alive. G
  • Brilliant work! Can you cross this data with the physical typography? I’ve always been curious if safer neighborhoods are uphill.

  • It would be interesting to pull the data in from previous decades and see how the elevation has changed in different areas.
  • @adrian – it’s just raw totals, grouped geographically. These aren’t scientific by any means, I basically took the underlying pattern and extruded it out and smoothed it a bit to make it look “pretty”. But basically each image is the aggregate numbers for a single year of crime data.
  • @richard – yes, there is some smoothing in effect, which means that the ridge along Shotwell St (for the prostitution map) is indeed a bit smoothed between peaks. That’s not to say that there are only two peaks at Shotwell and 19th and Shotwell and 17th. There are incidents in between as well, but the big peaks at those major intersections does mean that the ridge between them appears higher than the actual incidents along those blocks support. A lot of people have commented on the usefulness of maps like these. I want to stress once again: this was done as an art project much more than a useful visualization. My goal was not to provide useful information that one could act on.
  • “one trick pony. these maps add nothing of value to a standard color plot.” I disagree: allowing for a third dimension of elevation makes the reality of concentration clearer – and half the point of crime mapping is to measure concentration, not simply “intensity.”
  • Great idea and nice work on the graphics, but there are at least three improvements you should make to reveal *true* patterns. Forgive me if you already did these. 1) Availability bias – normalize for population density (i.e. per capita activity) 2) Sampling bias – normalize for the number of cops on the beat (geographic and crime type) 2) Frame bias – break it up by daytime and night time

The New Gold Mine: Your Personal Information & Tracking Data Online - WSJ.com - 0 views

  • the tracking of consumers has grown both far more pervasive and far more intrusive than is realized by all but a handful of people in the vanguard of the industry. • The study found that the nation's 50 top websites on average installed 64 pieces of tracking technology onto the computers of visitors, usually with no warning. A dozen sites each installed more than a hundred. The nonprofit Wikipedia installed none.
  • the Journal found new tools that scan in real time what people are doing on a Web page, then instantly assess location, income, shopping interests and even medical conditions. Some tools surreptitiously re-spawn themselves even after users try to delete them. • These profiles of individuals, constantly refreshed, are bought and sold on stock-market-like exchanges that have sprung up in the past 18 months.
  • Advertisers once primarily bought ads on specific Web pages—a car ad on a car site. Now, advertisers are paying a premium to follow people around the Internet, wherever they go, with highly specific marketing messages.
  • ...22 more annotations...
  • "It is a sea change in the way the industry works," says Omar Tawakol, CEO of BlueKai. "Advertisers want to buy access to people, not Web pages."
  • The Journal found that Microsoft Corp.'s popular Web portal, MSN.com, planted a tracking file packed with data: It had a prediction of a surfer's age, ZIP Code and gender, plus a code containing estimates of income, marital status, presence of children and home ownership, according to the tracking company that created the file, Targus Information Corp.
  • Tracking is done by tiny files and programs known as "cookies," "Flash cookies" and "beacons." They are placed on a computer when a user visits a website. U.S. courts have ruled that it is legal to deploy the simplest type, cookies, just as someone using a telephone might allow a friend to listen in on a conversation. Courts haven't ruled on the more complex trackers.
  • tracking companies sometimes hide their files within free software offered to websites, or hide them within other tracking files or ads. When this happens, websites aren't always aware that they're installing the files on visitors' computers.
  • Often staffed by "quants," or math gurus with expertise in quantitative analysis, some tracking companies use probability algorithms to try to pair what they know about a person's online behavior with data from offline sources about household income, geography and education, among other things. The goal is to make sophisticated assumptions in real time—plans for a summer vacation, the likelihood of repaying a loan—and sell those conclusions.
  • Consumer tracking is the foundation of an online advertising economy that racked up $23 billion in ad spending last year. Tracking activity is exploding. Researchers at AT&T Labs and Worcester Polytechnic Institute last fall found tracking technology on 80% of 1,000 popular sites, up from 40% of those sites in 2005.
  • The Journal found tracking files that collect sensitive health and financial data. On Encyclopaedia Britannica Inc.'s dictionary website Merriam-Webster.com, one tracking file from Healthline Networks Inc., an ad network, scans the page a user is viewing and targets ads related to what it sees there.

  • Beacons, also known as "Web bugs" and "pixels," are small pieces of software that run on a Web page. They can track what a user is doing on the page, including what is being typed or where the mouse is moving.
  • The majority of sites examined by the Journal placed at least seven beacons from outside companies. Dictionary.com had the most, 41, including several from companies that track health conditions and one that says it can target consumers by dozens of factors, including zip code and race.
  • After the Journal contacted the company, it cut the number of networks it uses and beefed up its privacy policy to more fully disclose its practices.
  • Flash cookies can also be used by data collectors to re-install regular cookies that a user has deleted. This can circumvent a user's attempt to avoid being tracked online. Adobe condemns the practice.
  • Most sites examined by the Journal installed no Flash cookies. Comcast.net installed 55.
  • Wittingly or not, people pay a price in reduced privacy for the information and services they receive online. Dictionary.com, the site with the most tracking files, is a case study.
  • Think about how these technologies and the associated analytics can be used in other industries and social settings (e.g. education) for real beneficial impacts. This is nothing new for the web, the now that it has matured, it can be a positive game-changer.
  • Media6Degrees Inc., whose technology was found on three sites by the Journal, is pitching banks to use its data to size up consumers based on their social connections. The idea is that the creditworthy tend to hang out with the creditworthy, and deadbeats with deadbeats.
  • "There are applications of this technology that can be very powerful," says Tom Phillips, CEO of Media6Degrees. "Who knows how far we'd take it?"
  • Hidden inside Ashley Hayes-Beaty's computer, a tiny file helps gather personal details about her, all to be put up for sale for a tenth of a penny.
  • "We can segment it all the way down to one person," says Eric Porres, Lotame's chief marketing officer.
  • One of the fastest-growing businesses on the Internet, a Wall Street Journal investigation has found, is the business of spying on Internet users.
  • Yahoo Inc.'s ad network,
  • "Every time I go on the Internet," she says, she sees weight-loss ads. "I'm self-conscious about my weight," says Ms. Reid, whose father asked that her hometown not be given. "I try not to think about it…. Then [the ads] make me start thinking about it."
  • Information about people's moment-to-moment thoughts and actions, as revealed by their online activity, can change hands quickly. Within seconds of visiting eBay.com or Expedia.com, information detailing a Web surfer's activity there is likely to be auctioned on the data exchange run by BlueKai, the Seattle startup.
