Client-provided
Files, plans and statements supplied for a stated project purpose.
Method
A visible path from origin to approved reality.
This page explains how we earn trust; what we deliver lives on the What We Deliver page.
A label describes what a record can support. Moving upward requires new evidence or named review — not stronger marketing language.
Source classes
Not every source carries the same authority.
Each class enters with a different origin, use boundary and review requirement.
Public context
Maps, policy, climate and market context used to frame a question.
Observations
Site visits, interviews and field notes tied to a date and observer.
Reference library
Precedents, typologies, standards and best-practice material.
The chain, in a real document
From source data to a claim you can check.
Four pages of a DEMO brief show the chain end to end. The evidence matrix lists what exists, the source page shows the satellite scene and its record, the processing page shows the indices and their statistics, and the source register names every source once.

Truth ladder
A visible ladder from origin to approved reality.
Each rung says what a record can support. It cannot be promoted by wording — only by new evidence or named review.
Client-provided
Origin and intended purpose are recorded.
Public context
Open context; never a survey substitute.
Screened
Basic security, format and purpose checks are complete.
Processed
Transformed with a stated, reproducible method.
Contextual
Supports direction without claiming measurement.
Modeled
Derived from geometry, assumptions or a model.
Projected
A possible future condition, not a built result.
Measured
Authoritative measured evidence with a stated basis.
Reviewed
Named human review is complete for the stated use.
Approved / built
Explicit approval or as-built evidence exists.

Provenance chain
Every important output keeps a visible path back to its source.
-
Source receipt
Uploader, project, purpose and timestamp.
-
Immutable identity
Original bytes and a stable hash.
-
Method record
What was transformed, how and with which limits.
-
Named review
Who reviewed the record for the stated use.
-
Controlled record
Delivery or publication status, rights and version.
Corrections create a new version. Superseded records stay traceable rather than silently overwritten.
Rights and publication QA
A delivery is not automatically a public case.
Publication is a separate gate with named review.
- Media rights — visual use and channel are cleared.
- Claim approval — only selected approved claims can publish.
- Privacy check — private identity and files remain protected.
- Named publication QA — a reviewer approves the export for public use.
No black box
There is no single number that stands in for judgment.
A landscape decision is not reduced to one public score. Every figure carries its source, method, scale and review status, so a reader can see what it can and cannot support.
Zümra vs system
The system prepares; a named human approves.
Automation assembles evidence and drafts. Design and evidence judgment, and the release decision, stay with a named reviewer.
