# Street Perception Evaluation Considering Socioeconomics (SPECS)
Repository for the Street Perception Evaluation Considering Socioeconomics (SPECS) dataset developed in the [It's not you, it's me: Global urban visual perception varies across demographics and personalities](https://github.com/matqr/specs) project.
This project was developed at the Future Cities Lab Global in the Singapore-ETH Centre in close collaboration with the [Urban Analytics Lab (UAL)](https://ual.sg/) at the National University of Singapore (NUS).
