Place Pulse is a crowdsourcing effort to map urban perception. By asking users to select images from a pair, Place Pulse collects the data needed to evaluate people's perceptions of urban environments. This data is also the data used to train Streetscore. Place Pulse was developed by Phil Salesses as part of his requirement to complete his master's thesis. The present version of Place Pulse was re-engineered by Daniel Smilkov and Deepak Jagdish.
