Citygram One: One Year Later

Citygram is a multidisciplinary project that seeks to measure, stream, archive, analyze, and visualize spatiotemporal soundscapes. The infrastructure is built on a cyber-physical system that captures spatio-acoustic data via deployment of a flexible and scalable sensor network. This paper outlines recent project developments which includes updates on our sensor network comprised of crowd-sourced remote sensing, as well as inexpensive and high quality outdoor remote sensing solutions; development of a number of software tools for analysis, visualization, and development of machine learning; and an updated web-based exploration portal with real-time animation overlays for Google Maps. This paper also includes a summary of technologies and strategies that engage citizen scientist initiatives to measure New York City’s spatio-acoustic noise pollution in collaboration with the Center for Urban Science and Progress (CUSP).
