NYC 311 Service Request Map

The newest application developed using DoITT GIS’ Webmap framework is the 311 Service Request (SR) Map (access here). Deputy Mayor Goldsmith along with Commissioner Post and Operations Director Liz Weinstein released the application at a press conference on Wednesday February 16, 2011 (read the press release).  The application provides the public access to open and recently closed (last five days) 311 service requests for 15 different major categories.

The service requests are geocoded on intake at 311 and are presented on a map for presentation and search capabilities and ostensibly ease of use.  The data is updated every twenty-four hours. One years worth of data represents over 4 million records (i.e., points on a map).  Service requests at a the same location (e.g., address, intersection) are aggregated and the size is graduated by the number of service requests at the location.  Therefore, locations with greater service requests will have points of a larger size.

Graduated Points example

Even taking these steps makes presenting so much data on a map challenging.  If you could envision a city-wide map of points representing months worth of data, there would be very little discernible information to pull from such a map. To address this, the initial map is a choropleth (aka thematic) map. A choropleth map shows shaded areas based on an incident rate or total count. In the case of the initial 311 map, it is the count of service requests by community district.  As you zoom in, the map will transition to points at a specific threshold when viewing points is more visibly tenable.

In addition to seeing the service requests on the map, users can use the identify tool to click on a point to see the actual service requests.  If there are multiple requests at a single location – see below example – a list is provided.  More detailed information can be found by clicking on each individual service request.

Happy Ferris Wheel Day

According to WikiHow, “Ferris Wheel Day is held on February 14 in honor of the American engineer and inventor George Ferris (born Feb 14, 1859). The Ferris wheel was invented for the World’s Columbian Exposition in Chicago, 1893. Since then it has been a must-have part of every fair and is beloved by many.”
To celebrate, why not take a trip to Coney Island and see the Wonder Wheel? This steel Ferris wheel was built in 1918 and opened in 1920. It has both stationary cars and rocking cars that slide along a track. The facts from wikipedia state that, “It holds 144 riders, stands 150 feet (46 m) tall, and weighs over 2,000 tons.”

If it is still too cold to take a ride on an outdoor Ferris Wheel, Toys ‘R’ Us has an indoor one at their Times Square location. It is located at 1514 Broadway, in what is considered the largest toy store in the world!

NYCityMap 9.0 Release Notes

Data Feedback

We’ve added a data feedback form to NYCityMap so that you can provide feedback to us regarding missing data, new data, or erroneous data.

Depending on the type of feedback you are providing the form will walk you through a series of questions to collect as much information as possible so that we can accurately incorporate your feedback. We look forward to hearing from you.

Other Map Themes

As you may already know, NYCityMap is built on the Webmap framework. This framework is available for city agencies to use in publishing their own spatial data. With this release we’ve added links to some of these web applications directly from NYCityMap.

SCOUT

The SCOUT application displays a map of the last date each community district was inspected by the SCOUT team. Searching for a specific location provides a map of specific service request locations created by the SCOUT team.

Transportation

The DOTMap provides access to a wealth of Transportation specific spatial data such as bike routes, truck routes, traffic cameras, ferry terminals and more.

Ability to view Subway Lines at Borough Level

In previous releases of NYCityMap it was only possible to view Subway Lines at the Neighborhood level. This is the level at which Subway Stations are also visible. With NYCityMap 9.0 you now have the ability to turn on the Subway layer at the Borough level and view the lines without the stations. You can still zoom into the Neighborhood level to view stations though.

New Business Acceleration Team

New Business Acceleration Team (NBAT) locations were added to the City Programs menu.

NBAT is a new initiative providing eligible new restaurants, bars, bakeries, and butcher shops a streamlined program to become “kitchen ready.” NBAT transforms the way entrepreneurs deal with City government by working with new businesses to help open their doors more quickly, reduce costs, and provide jobs for the community.
