Before and after lot vacancy

Justin Blinder used New York's city planning dataset and Google Streetview for a before and after view of vacant lots.

Vacated mines and combines different datasets on vacant lots to present a sort of physical facade of gentrification, one that immediately prompts questions by virtue of its incompleteness: “Vacated by whom? Why? How long had they been there? And who’s replacing them?” Are all these changes instances of gentrification, or just some? While we usually think of gentrification in terms of what is new or has been displaced, Vacated highlights the momentary absence of such buildings, either because they’ve been demolished or have not yet been built. All images depicted in the project are both temporal and ephemeral, since they draw upon image caches that will eventually be replaced.
