CS-UDT flood digital twin

2026

A crowd-sourced urban digital twin for hurricane flooding in Jacksonville, with a zero-install citizen client and a planner dashboard. The demo runs on simulated data.

Datasheet

Client
Zero-install browser client
Pipeline
LLM parsing of citizen reports and social posts into hazard events
Verification
Three-channel convergence rule: official sensor anomaly + citizen report + social post in the same map cell
Engagement
When two channels agree, nearby residents get a one-tap verification quest
Replay
Simulated replay modeled on Hurricane Irma (Sep 10–12, 2017): first three-channel confirmation 10.8 hours into a 30-hour replay; four confirmed cells and three open quests at the peak
Data
Simulated replay and synthetic community content
