Two projects from the lab

What is murmur?

neighborhood conditions

shape different responses.

Equipped with 100+ metrics spanning demographics, health, housing, environment, mobility, and equity, the model explores how neighborhood conditions shape responses to proposed scenarios. These are modeled estimates, not observed effects or the voices of actual residents.

Multi-resolution model

Three resolutions. One interconnected model.

Parcel scale~25 m

100+ data fields per cell.

Block scale~250 m

{
  "displacement_risk": 0.73,
  "health_burden": 0.61,
  "connectivity": 0.82,

}

Aggregate layer. Composite indices summarize conditions across children.

Neighborhood scale~1 km

Policy agent. Acts on behalf of its residents' interests, zoning constraints, and neighboring influence.

Platform

A living model
of every neighborhood

murmur divides your city into hex cells, each carrying 100+ real-world data fields. Apply a scenario — a new bike lane, a transit line, a rezoning — and see cascading impacts across every neighborhood.

100+ data fields per cell

Demographics, health, pollution, housing, transit, amenities, schools, and network metrics across every cell.

Scenario modeling

Test infrastructure changes, policy shifts, and investment scenarios. See cascading impacts across housing, health, environment, economic, mobility, education, and safety domains.

Equity-first analysis

Every scenario shows who benefits and who bears the cost — with displacement risk, equity breakdowns, and ripple effects mapped across the city.

Network intelligence

Neighborhoods are connected the way real cities work: by commute patterns, shared school districts, pollution corridors, housing markets, and economic ties.

Research direction

Fork a scenario.
Compare futures.

The long-term goal is a shared baseline with independent scenarios, so teams can explore an idea and compare its assumptions with other proposals.

This collaboration workflow is a development direction. Data freshness and coverage depend on the underlying sources.

About the lab

Fieldwork meets
software.

Murmura Labs is an independent lab founded by Elijah, based in San Francisco. The work spans geospatial data engineering, urban modeling, 3D reconstruction, and interactive web tools.

We explore how data, fieldwork, and software can help us understand and improve the built environment.
