Publish the work you already do, with its evidence attached.
Substriva is an independent public record of who looks after public land and what has actually been documented about it. In a scoped pilot, councils, park agencies and committees of management can test how existing records could be structured, reviewed and, where authorised, prepared for publication.
Context, not clearance. Substriva is independent and is not a government service.
See the workflow before you ask your team to change theirs.
Substriva sits beside existing source systems to make land context easier to review, trace and publish without turning missing information into a claim.
Demonstration film. Any works records shown are synthetic sample data, not council records. No council participation or endorsement is implied. Context, not clearance.
Why a land manager would use it
Residents, contractors and other agencies ask what was done on public land, and when. Most of the answer already exists in works orders and contractor notes, but it isn’t findable, and it doesn’t say where the work happened.
Substriva turns those records into checkable public entries: each one tied to its source, to where the work was walked, and to a person who reviewed it. The record also says clearly what it does not establish.
What a land manager actually does
- Managed area
Start from a reserve, park or zone you already look after. Its boundary comes from your own GIS, a public-land parcel, or a walk.
- Treatment / context record
What was done, the month, the source it rests on (for example a works order), and what the record does not establish.
- Pocket-mode capture
Press Start, put the phone away, walk the work area. Location is recorded only while it says RECORDING. Pause means nothing is recorded.
- Finish
The summary shows everything that was captured, including GPS problems, which are flagged, never silently fixed.
- Geometry review
Someone other than the person who captured it checks the track and resolves anything flagged.
- Evidence QA
Sources are checked and the public label is derived from them. Labels are never chosen by hand.
- Publication gate
Only a person you grant publishing rights can release a record. If you publish nothing, nothing is public.
- Public map
A generalised, dated, sourced record, with its limits stated beside it.
What gets geo-recorded, and what never leaves your team
Recorded
- The area walked while the phone said RECORDING
- The activity and the month
- The source document it rests on, with a fingerprint (hash)
Never public
- Who captured or reviewed it
- The walked track and exact times
- Device and GPS accuracy
- Private notes
Never recorded
- Anything while paused or before Start
- Location outside an active session
Public locations are generalised (the demonstration uses 25 m squares). Sensitive sites can show the site outline only, or nothing at all.
How evidence is labelled
Every public record carries a label derived from its sources, never chosen by hand. Problems are shown loudly rather than smoothed over.
- Official record
- From the land manager’s own record or an official public record, published through an authorised publisher.
- Corroborated
- Two independent sources agree (different origins, not two copies of one document).
- Location recorded
- Where the work was recorded by GPS and checked by a reviewer. Says where, not what was applied.
- Unknown
- Nothing published says either way. Unknown is not safe, and not untreated.
- Caution
- Something is unresolved, conflicting or out of date. Read the details before relying on it.
What happens before anything is public
- A second person reviews where the work was recorded.
- Sources are checked; herbicide and pesticide work can only be recorded from a document such as a spray record, never from an observation.
- Someone you have granted publishing rights decides to publish, or not.
- Every step is written to an append-only log. Corrections add a new version that supersedes the old one; nothing is quietly edited.
What reaches the public map
The public may infer
- A named land manager recorded this activity, in this month, in the marked area.
- A second person reviewed where it was recorded before it was published.
- Which sources it rests on, and when they were retrieved.
The public may not infer
- Anything about safety. A record does not make an area safe, and neither does the absence of one.
- That anywhere without a record was not treated. No record means UNKNOWN.
- That nothing else happened here before or since.
- That any council, agency or dataset custodian endorses Substriva.
Unknown, and why no record never means safe
UNKNOWN means nothing published says either way. Where there is no record, Substriva says so in these words: “We did not locate a relevant public record in the sources checked. This does not mean the land is untreated, and it does not mean anything is being withheld. It means our search of the listed sources did not find a document, and the sources we checked are listed below.”
Context, not clearance. A record describes what was documented. It is never a safety assessment, and a place without a record is not untreated. For conditions at a specific place, contact the land manager.
How a pilot could work
One land manager. One bounded reserve or corridor. About 6–8 weeks.
- Scope, data handling and cost agreed in writing before anything starts.
- Your team records and reviews; your publisher decides what, if anything, becomes public.
- At the end: an export of the records and a short findings summary.
- Choose one bounded reserve or corridor and one contact
One land manager, one place you already manage. Confirm the working boundary and the records in scope before the pilot begins.
- Agree the scope, data handling and cost in writing
Before anything is captured: what gets recorded, who reviews, who may publish, how precisely locations are shown, which sites stay hidden, how long data is kept and how it is returned, and the agreed cost.
- Your team records works as they happen
A treatment or context record, plus a pocket-mode GPS walk. Nothing is public at this stage.
- Your reviewer checks, your publisher decides
Substriva flags problems; your people resolve them. If you publish nothing, nothing is public.
- Review together after about 6–8 weeks
You receive an export of the records and a short findings summary, and decide whether anything should continue. Taking part implies no endorsement.

Read the film transcript
Start with the land you look after. One place can have many records: who manages it, what is documented, and where those records apply. Trace each record back to its source, custodian, licence, retrieval date, integrity and stated coverage. Keep field observations in context and bring the record to your team. Check the sources and state the limits. Clearer works records sit alongside your GIS, not instead of it. Reviewed does not mean public: authority stays with the land manager, and a separate authorised publisher decides what can be released. Substriva keeps the record legible; it does not make the decision. Start with one land manager and one bounded reserve or corridor for about six to eight weeks, ending with a records export and short findings note. Scope, data handling and cost are agreed before anything starts. Context, not clearance. Explore the demonstration and ask about a pilot. Substriva. Land, made legible.
Taking part implies no endorsement of Substriva by your organisation, and Substriva will not describe you as a partner unless you agree in writing.
