Citi Bike NYC: the first and last mile quantified

The NYC Department of Transportation revealed last week where they’d like to place 400 or so bike share stations in Manhattan and parts of Brooklyn and Queens, as the next step in the city’s new bikeshare program starting this summer.  (By next spring the city plans to locate a total of 600 bike share kiosks for [...]

Putting transit GIS data to use

Recently I’ve come across several examples of people being able to use the MTA subway and bus data that I had converted to GIS format a couple of years ago.  I know that I’ve been able to put the data to good use.  But I’m especially glad to see others benefiting from my efforts. So [...]

Proposed Congressional districts for NYS available in GIS format

UPDATE March 6, 2012 We’ve added Congressional districts as proposed by District Court Judge Hon. Roanne Mann to our interactive redistricting site. Here’s a link that compares District 9 (Rep. Turner, in NYC) with one of the proposed districts that it would become under her proposed lines: http://t.co/01K4hMu8 We also submitted a letter today to the [...]

NYC’s open data legislation: reading between the lines

TL; DR (i.e., the summary) NYC is about to adopt what some are calling “landmark” and “historic” legislation regarding open data.  Does the hype match the reality? I offer the analysis below not as a critique of the City Council.  I think they probably tried to negotiate as good a bill as they thought they [...]

Our team at the Center for Urban Research is collaborating with The New York World to analyze the impacts of redistricting in New York State.  The latest effort was featured today on the front page of the Times Union; it focuses on how the majority parties in the State Senate and Assembly would likely retain — [...]

Access to local GIS data

Rob Goodspeed has an interesting post about his survey of the policies and practices of local governments in Massachusetts regarding GIS data. It looks like a good read. In my experience (in New York State), local governments can have more interesting GIS data (for example, tax parcels and real property records) than the state or [...]

Some NYC OpenData improvements – small but important victory!

I noticed today that NYC’s new OpenData site (on the Socrata platform) has made some modest improvements since I blogged about it earlier this month, and since several people have responded to comments from Socrata’s CEO. In particular, many of the files listed in the Socrata/OpenData site as “GIS” files or “shapefiles” are now actually [...]

Pretty NYC WiFi map, but not useful beyond that

@nycgov posted a tweet on Friday touting the map of WiFi hotspots on the new NYC OpenData site.  I was impressed the city was trying to get the word out about some of the interesting data sets they’ve made public. It was retweeted, blogged about, etc many many times over during the day. The map [...]
