How it works
From satellite images to a decision in three steps
- STEP 1
Collect
We map buildings from open imagery and survey data, and mark where each record comes from.
- STEP 2
Model
Hazard and vulnerability models turn buildings into exposure and expected loss, with the method documented.
- STEP 3
Verify and share
Partners check results against field reports. Verified data is released openly, with a version history.
Platform
Model, query, verify
Run exposure queries on open building data and compare the results with field reports.
- Every figure links to its source and method
- Download as CSV or GeoJSON, or use the API
- Versioned releases, so reports stay reproducible
Example query
SELECT month, buildings_exposed FROM district_a WHERE hazard = 'flood'

Questions
What people ask us first
Is the data free to use?
Yes. Verified releases are open under a permissive license, with attribution. Placeholder answer for this mockup.
How accurate are the building records?
Each record carries its source, date and a confidence level. Partners check samples against field reports before a release is marked verified.
Can we use it in our own models?
Yes. Download the full layer or use the API. Releases are versioned, so a report can always point to the exact data it used.
Who pays for this work?
The foundation is funded by grants and partner contributions. Placeholder answer for this mockup.
