Interactive NY redistricting map with cartoDB and more

New York State, like all other states, is in the midst of redrawing its legislative district lines. To help you follow along, our team at the Center for Urban Research has launched an interactive redistricting map for New York.  We collaborated with The New York World to develop the maps (though we encourage anyone and everyone [...]

Proposed NYS Senate & Assembly districts available in GIS format

UPDATE February 5, 2012 You can visualize these proposed districts in relation to the current New York State Senate and Assembly districts with our new interactive redistricting map.  We developed the interactive map in collaboration with The New York World, and here’s an article using the maps to describe the redistricting process in the Empire [...]

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 [...]

NYC’s new OpenData website: soars and falters all at once

UPDATE (10/13/11) This evening I received a call from NYC DoITT.   They were mainly calling to tell me that they changed the official rules for BigApps 3.0.  Yesterday the rules said that no new data would be added to the OpenData site until after the BigApps competition.  As I said in my blog, why wait?  [...]

NYC bikeshare maps & spatial analysis: an exploration of techniques

Two weeks ago New York City announced an ambitious bikeshare program, designed to provide 10,000 bikes at 600 bike-sharing stations in Manhattan and parts of Brooklyn by next summer.  I had two immediate thoughts: I wondered if all 10,000 new bikers will ride like delivery staff and further terrorize me and my pedestrian 5-year olds; [...]

Mapping Hurricane Irene in NYC (plus some thoughts on the city’s digital response to the storm)

A disaster, natural or otherwise, always creates an opportunity to demonstrate the power of maps. Hurricane Irene did not disappoint. In New York City, which hadn’t seen a hurricane of this magnitude in decades, there were at least a half dozen websites with interactive maps related to the storm (plus at least one PDF map [...]

Innovative map comparisons – Census change in 15 cities

Our team at the Center for Urban Research (at the CUNY Graduate Center) has updated our interactive maps showing race/ethnicity patterns from 2000 and 2010 in major cities across the US. We’ve enhanced the maps in several ways: Added more cities. We now have 15 major urban regions mapped across the US (Atlanta, Baltimore, Boston, [...]

Slippy maps, meet before-and-after jQuery slider (introductions by OpenLayers)

Our team at the Center for Urban Research (at the CUNY Graduate Center) has launched a set of maps showing race/ethnicity patterns from 2000 and 2010 in major cities across the US.  The maps combine several mapping/web technologies that offer a new way of visualizing population change.  This post explains how we did it. (And [...]
