Urban Mosaic: Visual Exploration of Streetscapes Using Large-Scale Image Data

Urban planning is increasingly data driven, yet the challenge of designing with data at a city scale and remaining sensitive to the impact at a human scale is as important today as it was for Jane Jacobs. We address this challenge with Urban Mosaic,a tool for exploring the urban fabric through a spatially and temporally dense data set of 7.7 million street-level images from New York City, captured over the period of a year. Working in collaboration with professional practitioners, we use Urban Mosaic to investigate questions of accessibility and mobility, and preservation and retrofitting. In doing so, we demonstrate how tools such as this might provide a bridge between the city and the street, by supporting activities such as visual comparison of geographically distant neighborhoods,and temporal analysis of unfolding urban development.Comment: Video: https://www.youtube.com/watch?v=Nrhk7lb3GU

African Americans, Gentrification, and Neoliberal Urbanization: the Case of Fort Greene, Brooklyn

This article examines the gentrification of Fort Greene, which is located in the western part of black Brooklyn, one of the largest contiguous black urban areas in the USA. Between the late 1960s and 2003, gentrification in Fort Greene followed the patterns discovered by scholars of black neighborhoods; the gentrifying agents were almost exclusively black and gentrification as a process was largely bottom-up because entities interested in the production of space were mostly not involved. Since 2003, this has changed. Whites have been moving to Fort Greene in large numbers and will soon represent the numerical majority. Public and private interventions in and around Fort Greene have created a new top-down version of gentrification, which is facilitating this white influx. Existing black residential and commercial tenants are replaced and displaced in the name of urban economic development

Neighborhood as spatial project: making the urban order on the downtown Brooklyn waterfront

This article argues for a reconceptualization of one of the most basic concepts in urban studies: the neighborhood. Traditionally neighborhoods have been understood as clearly bounded, quasi-Westphalian containers or as ‘natural areas’ of urban community. But this approach is widely acknowledged to be under-theorized. And it fails to account for the ways in which the production of neighborhood is inherently political and often conflictual. After reviewing the ways in which neighborhood has been used in urban sociology and urban planning, this article offers a critical conception of neighborhoods as ‘spatial projects’ on the submetropolitan scale. This approach captures the ways in which neighborhoods are not abstract spaces on a city map, but the uneven, unequal products of complex, ongoing struggles between various groups and institutions. This approach is developed through an ethnographic and historical case study of neighborhood formation in one part of Brooklyn, New York. The article concludes with a discussion of how the language of spatial projects refocuses urban research on the political and economic forces that produce neighborhood in the contemporary city
