Challenge · Dead Zone Detective
Holmes now stretches beyond housing intelligence. This challenge surface ingests Philadelphia connectivity data, scores tract-level access risk, maps public Wi-Fi resilience, and gives judges an operational view of where digital frustration is likely to hit hardest.

Demo Story
Forecast where connectivity complaints are likely to spike, before an ops team gets overwhelmed.
Blend tract vulnerability with public Wi-Fi resilience so the map is actionable, not just descriptive.
Let judges move from the strategy page into a live Leaflet map with tract detail and site context.
Keep the experience accessible and explainable so both civic reviewers and field operators can use it.
Equity Pattern
The neighborhoods hit hardest by vacant properties and housing blight are the same ones losing the connectivity battle. Abandoned buildings depress investment, shrink the tax base, and push out the infrastructure that keeps communities online. It is not a coincidence — it is the same disinvestment showing up in two different datasets.
We ingest Philadelphia tract-level connectivity indicators and city Wi-Fi locations instead of using fabricated demo data.
The live Leaflet experience shows where access stress is concentrated and where local fallback infrastructure exists.
Risk scoring blends internet access gaps, device scarcity, income pressure, and site coverage so the map highlights who gets left behind and why.
