Verify who manages a place
Open a place, follow the cited authority source and tell us when the manager or boundary is wrong.
Explore the atlas →THE SUBSTRIVA MISSION
Make land context legible, one source-checked contribution at a time.
Substriva is built so an ordinary person, a council officer and a researcher can work from the same map without pretending they have the same authority. Contributions improve source coverage, corrections and provenance. They never become a safety score or medical claim.
CHOOSE A CONTRIBUTION
Useful work should feel clear and finishable.
These are contribution missions, not behavioural rewards. No points are awarded for entering a location, collecting biological material or making a health claim.

Improve a public record
Submit a correction with a stable source, date and scope. A human review is required before publication.

Bring a land manager into the loop
In a pilot, land managers can test how authoritative GIS and existing records are read alongside Substriva, review how their evidence is represented, and decide what, if anything, should become public.

Stress-test the method
Researchers and careful reviewers can challenge provenance, uncertainty and temporal claims without turning unknowns into conclusions.
Read the method →THE RULES OF THE MAP
The interface can be playful. The evidence cannot be.
Context, not clearance. No map state means a place is safe, clean or free of a treatment or biological risk.
Unknown stays unknown. Missing data never becomes an inferred negative.
Authority stays visible. Council GIS, state datasets, submissions and Substriva records are visibly different layers.
Time matters. A current condition does not reconstruct a past event; dates and source scope remain attached.
Health stays separate. Substriva can preserve environmental context without giving personalised medical advice or encouraging substance use.
