What's with this city, that we endlessly dissect it, glorify it, wonder how exactly we fit into it?

Sandy Island, located in the Pacific Ocean off the coast of Australia, occupies about about 45 square miles of the Coral Sea. It was documented in 1772 and appeared on a 1908 admiralty chart and in Google Maps. The problem is, Sandy Island never existed.

Simon Garfield tells the history of maps from the early explorers’ maps to the satellite renderings on our smartphones. He explains how maps reflect the best and worst of what makes us human. His book On the Map: A Mind-Expanding Exploration of the Way the World Looks is full of fascinating tales of cartographic intrigue, outsize personalities, and “pocket maps.”

Snow was still dumping down on Boston Friday evening when the city had to pull down its public website for tracking snow plows. Within a couple of hours of snowfall the site had over a million requests from users. Boston's total population is 625,000.
"[The site] couldn't handle all the traffic," said John Gulfoil, spokesman for Mayor Thomas Menino. "It was hurting our efforts to actually track our own plows," he said.
The city had built the GPS-enabled tracking website so the public could watch along in real time as plows made their way around the city street by sodden street.
After the blizzard of 2010, New York City was trapped in piles of snow. Cars, buses, even ambulances were abandoned in streets that went unplowed for days. stranded on unplowed streets and citizens crying foul that they couldn't tell when and where the cleanup was coming. In the aftermath, NYC Mayor Mike Bloomberg said, "there was a discrepancy between information coming into and out of City Hall and what people were actually experiencing on the streets." He vowed to track each plow using GPS in the future. (More on that below.)
The blizzard this past weekend that hit Boston hardest, brought with nearly three feet of snow and the first real test (that we are aware of) of a GPS-managed snow plow fleet in a major snowstorm.
Boston has had a private GPS tracking system in place for smaller storms since. This was the first time the public was able to watch the plows move in real-time along with city officials.
The catch is that the same GPS system that populated the dots on the public website map also powered the Department of Public Works operational maps at its command center. The flood of interest from the public was clogging the servers and preventing plow fleet managers from doing their jobs.
The Department of Public Works mustered private contractors to join the city fleet in removing more than three feet of snow from city streets. The GPS tracking system has been in place for years and helps hold the drivers accountable because managers can see where they are. "They can't hide," as Gulfoil puts it. “Hopefully next time there’s a major storm we’ll have all the bugs worked out,” Gulfoil said.
New York City had a similar website in place, though with much less snow to contend with -- and citizens out sledding and such in higher numbers -- the PlowNYC website proved less popular and less problematic. Keith Mellis of the NYC Department of Sanitation didn't have traffic numbers immediately available. "We had no interruption," he said. "It works."
You can see where plows went in NYC hour by hour on this visualization of the PlowNYC data extrapolated by plow-watcher Derek Watkins.

Washington, D.C.'s Capital Bikeshare released its latest batch of customer trip data -- and the fine folks at Mobility Lab turned it into an interactive map. What's interesting about this visualizer is that it sorts trips by neighborhood cluster.
Instead of seeing all the trips everywhere -- which is beautiful -- you can see how a given station connects to the areas around it. The more rides between two stations, the thicker the red line. Click on most downtown stations and it looks like a starburst of rides.
Trips on the National Mall tend to stay on the National Mall or head over the Jefferson Memorial.
Mobility Lab has also set the map so you see the direction of trips, including "unbalancedness" between stations. That's when trips tend to be in one direction more than another. It's not so surprising that more people ride downhill on Connecticut Avenue from the Van Ness station to Dupont Circle. But it is interesting to see how many more people ditch the heavy bike share bikes at the bottom and return by some other, presumably less tiring, means. Of the 203 trips between those two stations in the 4th quarter of 2012, 82 percent of them were downhill.
(Read TN's article on how DC rebalances bike share stations here.)
Michael Schade over at Mobility Lab has pulled out a few more interesting data points. Alexandria, Virginia, joined CaBi last year. Most of those bike share trips appear to be heading to or from the two Metro stations. So Schade concludes bike share in Alexandria is being used to solve a last-mile transit problem.

If there's one place you'd expect to find an enthusiasm gap for Obama supporters, it'd be in Madison. But after running into weary and cynical voters in Colorado and Iowa, Wisconsin voters sounded remarkably resolved for another contest.

Using data from the New York City police department, WNYC mapped all street stops by police that resulted in the recovery of a gun last year. The digital map shows an interesting pattern — the areas where the NYPD finds guns are not necessarily the places where the police are devoting the most stop-and-frisk resources.

When Apple V.P. Scott Forstall unveiled the company's new operating system last week, he was breathless with enthusiasm. "Next is Maps," he said. But not included: Transit directions. Bay Area BART trains? Not there. DC's Metro? Not there? Boston's T? Not there.
"I was, first off, kind of surprised," said Joshua Robin, innovation director for the Massachusetts Bay Transportation Authority. "For the last couple of years, it's been a huge benefit to our riders to have transit as an option."
iPhones have been relying on Google Maps, which do include transit directions. But now that Apple is working on its own system, it dropped transit. Pro-transit groups started a petition to get Apple to reconsider.
Apple isn't commenting, beyond what Forestall said at the announcement: "Instead of trying to build those ourselves, we are going to integrate and feature and promote your apps for transit right within the Maps app in iOS 6."
So for a while at least, you'll have to download them yourselves.

New York's sixth congressional district, in Queens, like the rest of the borough, was once dominated by Jews and Catholics. But redistricting this year made Asian Americans almost forty percent of the district, giving an Asian American candidate, Grace Meng, a shot at being New York's first Asian American elected to Congress.
But first, she'll have to beat Democratic two candidates with deep roots in Queens politics in next week's primary: City Councilmember Liz Crowley, and state Assemblymember Rory Lancman. Click over this interactive map to see how the district has changed in just ten years. The winner of the June 26 primary will face a Republican in November.

As we've been reporting, New York City DOT is quietly presenting almost final maps of bike share stations. (We've made an interactive map, showing how many bikes will be at each station, below.)
The City DOT isn't making it easy -- to see their almost final maps of bike share stations, you have to physically attend a community board meeting. Jim O'Grady did that -- took a bunch of cell phone photos of slides presented by the DOT -- and we've converted them into a map.
(We're missing a segment, one slide -- so sorry, the area just east of City Hall down to the river. We'll update as soon as we can.)
Some notable highlights:
* You can get pretty close to the World Trade Center -- about a block away -- but not in the security zone.
*There's one near Stuyvesant High School.
*There's one at the Wall Street Ferry dock, and a whole bunch by the Staten Island Ferry.
*There's one next to the Stock Exchange -- but it hasn't yet been approved by the Department of Homeland Security, which controls the area.
We'll be attending as many of these future meetings as we can -- if you go, send us photos! -- and continuing to map them, until the city DOT puts out its own maps. These maps have yet to get final community board and city sign-off, though we've heard a generally positive reaction from community boards.
The New York Times has this map of midtown bike stations.
Here are the upcoming community board meeting:
- Manhattan Community Board 1: May 3
- Manhattan Community Board 2: Transportation Committee, May 8, Full Board, May 24 (DOT presentation not yet scheduled)
- Manhattan Community Board 4: May 2 (vote on resolution on tentative map)
- Manhattan Community Board 5: May 31
- Manhattan Community Board 6: May 17
- Manhattan Community Board 7: not yet scheduled
- Brooklyn Community Board 2: information not yet available
- Brooklyn Community Board 3: Full Board, May 7, Transportation Committee May 8
- Brooklyn Community Board 6: May 17 (tentative)
The program is slated to start in July -- with an annual pass costing $95, a weekly pass $25, and a day pass for $10. That gets you 45 minutes per ride, with an escalating scale upwards after that.
