ARJUN
Granted Patent - Augmented Reality Based Environmental Data Capture
ARJUN is AranyaCarbon's measurement system for forest carbon. It finds the trees, fixes each one to a cell on a deterministic grid, measures it in the field, and locks the record so the same tree can be found and remeasured years later. Built on AranyaCarbon's patented technology, it turns a forest from something estimated at a distance into something counted, and then re-counted.
ARJUN is two things working together: ArjunField, the app the crew carries, and the ARJUN Digital Twin, the console where the forest becomes a record you can interrogate.

ARJUN · how it works
1. Count
Satellite and aerial imagery tell us how many trees to expect in each cell, and where the crew has not yet been. Imagery never creates a tree: it sets the count the field has to account for.

CANDIDATE DATA
2. Place
The surveyor places every tree from where they stand, and its position is fixed where they stood at the trunk. Each tree belongs to a fixed cell on a deterministic grid. The cell is the address: it does not move between visits, and it does not depend on the device that visited.

3. Lock
In the field, a surveyor confirms the tree, measures it, identifies the species and locks the record. Capture works offline. Once locked, the record is immutable: corrections are new entries, never edits.

4. Re-verify
Next cycle, the crew returns to the same cells and measures the same trees. Growth, mortality and disturbance are observed at the tree rather than inferred from a sample.

Bring what you have.
ARJUN ingests the data a forest already has: existing inventories, aerial surveys, point clouds, departmental records. Those tell you what has been seen before. ARJUN measures what they cannot tell you, and puts both on the same grid.


ArjunField
Capture at the tree, by the people who are already in the forest.
-
Augmented reality shows the surveyor the cell they are standing in and holds the tree in view while it is measured. The overlay is anchored to the ground, not to the phone, so it stays where the tree is, and the record says how precisely each tree was placed.
-
Diameter, height class, species and condition are recorded against the cell, with the photographic evidence attached to the record.
-
Fully offline. Nothing in the forest depends on a signal. Records queue on the device and sync when the crew comes back into coverage.
-
Built for a trained local surveyor, not a specialist. State programmes run on crews recruited and trained locally, which is where the employment case comes from.
-
Runs on ordinary Android hardware today, with survey-grade positioning and AR eyewear supported as the deployment requires.
ARJUN Digital Twin
Where the forest becomes a record you can question.
-
Every project, boundary, cell and tree in one place, from a state down to a single stem, with the imagery and the census in the same view.
-
Organisations, divisions, ranges and sites mirror how a forest department is actually structured, so people see the forest they are responsible for and no more.
-
Every tree carries its own history: when it was locked, who captured it, what changed at each cycle. The crew's route is recorded with the census, so a verifier can see the ground was covered rather than sampled.
-
Exports built for the people who check the work: data packages a verification body can trace back to the stem.

Coming Soon: see the forest, not just the data
A visual layer that renders the measured census as a forest you can move through, and shows what changed between cycles. Measured cycles are shown as measured; anything projected is labelled as a projection. The census decides what changed; the rendering only decides what it looks like.
A number is only worth what can be traced behind it
Carbon accounting fails at the audit, not at the estimate. ARJUN is built so that every figure it produces can be walked backwards to a specific tree, in a specific cell, measured on a specific day by a named surveyor.
Immutable by design
A locked record is never edited. A correction is a new entry with its own timestamp and author, and the earlier value stays visible. Nobody can quietly improve last year's numbers.
Evidence attached
Photographs, position quality, device and surveyor travel with the measurement, not in a separate file that can drift away from it.
Honest about what it is
A tree seen from space is a number, not a tree. Imagery says how many to expect in a cell; only a field lock creates a tree. Expected and locked are reported separately, cell by cell.
What ARJUN does not do
ARJUN does not rate projects, issue credits, trade them or make regulatory filings. It produces the measured evidence that the people who do those things depend on. That separation is deliberate, and it is what keeps the evidence worth trusting.
