New York City Maps

As a resident of New York City, I'm fascinated by the structure and ecology of the city. This ongoing project utilizes the vast open data resources of the city to expose new insights about New York.

Manhattan 311 Noise Complaints

View image full-size

311, New York's Information and Services phone line, collects noise complaints — this graphic maps this data from 2012 in Manhattan. Noise complaints reveal the concentration of activity in the city as well as many smaller stories, such as the construction of the Second Avenue subway line, idling buses on the Upper East Side, and the homes of the loudest dogs (or the least patient neighbors). Specific complaints show dramatic differences among neighborhoods in Manhattan and where the city invests the most of its development resources.

New York City Street Trees

View image full-size

New York City took a census of the entire city's street trees in 2005; this is a visualization of that data. Though I am especially fond of the contrast between the concrete jungle and the actual jungle that grows along its gridiron, this data also reveals the residential anatomy of the city. Dense concentrations of trees can be seen as a proxy for popular or affluent neighborhoods. Notice how lush the Upper East Side, the West Village, and Cobble Hill appear in relation to nearby neighborhoods.

San Francisco also published a database of their street trees. Please contact me if you're interested in prints of any maps on this page.

Process

This project relies primarily on Excel and Processing. I use initial, rough renderings to explore and reveal the contours of the data, then finesse both the information and the visualization to enhance comprehension and aesthetic appeal.

An initial look at the data that revealed a high concentration of complaints in Manhattan.

Alternate depictions of noise complaints. The concentric circles used in the final rendering best balanced small and large complaint volumes while visually suggesting noise and interference.

Alternate approaches with circle size, transparency, and hue for the street tree data.
