Urban Data & Decisions
summary
Built a city research stack: a curated data hub (1200 public feeds plus restricted sets), a quantified community in Greenpoint instrumenting ~10,000 people, and an urban observatory that fuses 1-foot lidar, 600 traffic cameras, hyperspectral (800+ bands) and longwave IR (7–13 μm). Deliverables include 50 low‑cost ($85) MEMS noise nodes (±2 dB, 15‑second audio snippets, 100 planned), a pedestrian‑count neural net (~60% accuracy), remote detection of soot plumes and freon/acetone sources, hypertemporal 120 Hz imaging of grid phase, and agent‑based crowd models. Overall systems work and yield actionable signals.
