Aerial-to-plan comparison
Bring new aerial imagery into a repeatable comparison against the approved surface plan.
Quarterly surface plans for South African mines
From a new aerial view to surveyor-approved plan updates.
TerraDraft proposes polygon changes against the latest approved surface plan, gives the responsible surveyor full review control, and prepares an auditable output for DMR submission.

The first product
A smaller drafting burden for a recurring regulatory job.
Quarterly surface-plan updates require skilled, repetitive comparison between current aerial information and the mine's approved plan. TerraDraft is being shaped around that one practical job first.
The MVP does not attempt to replace CAD platforms or professional surveying. It concentrates on change detection, polygon drafting, review history and a controlled handover to the responsible surveyor.
See the site differently
Survey the change before redrawing the plan.
A current aerial view gives the review process a clear starting point. TerraDraft is being designed to turn visible change into structured polygon proposals that a surveyor can inspect and approve.
Aerial context first. Professional judgement throughout.
The quarterly workflow
Five clear steps with a human decision at the centre.
- 01Upload
Add the latest aerial view and the current approved surface plan.
- 02Compare
Align the source material and identify areas that appear to have changed.
- 03Propose
Create traceable polygon updates without overwriting the approved source.
- 04Approve
The surveyor reviews, corrects, accepts or rejects every proposed change.
- 05Prepare
Package the approved plan and audit record for DMR submission.
Polygon change proposals
Turn visible change areas into editable proposals with source and version traceability.
Controlled review
Keep approval, correction and rejection decisions visible before any plan is released.
Submission record
Retain the evidence needed to understand what changed, who reviewed it and what was approved.
Professional control
AI assists the drafting. The surveyor owns the decision.
TerraDraft is designed as a human-in-the-loop workflow. It can identify, organise and propose changes, but it cannot approve a plan or replace the professional responsibilities of the appointed surveyor.
No silent changes
Proposals remain separate from the approved source until reviewed.
Explicit approval
Each release is tied to a responsible professional's decision.
Auditable history
Inputs, proposed edits, corrections and approval status remain traceable.
Focused compliance
The MVP output is validated around the quarterly DMR workflow.

Product facts
What the first TerraDraft product is and is not.
Who is TerraDraft for?
South African mines and survey teams responsible for recurring surface-plan updates and professional review.
Does TerraDraft replace the surveyor?
No. The product proposes drafting changes. The responsible surveyor reviews and approves the released plan.
Does it submit directly to the DMR?
The MVP prepares an approved plan output and audit record. Submission remains part of the mine's controlled professional process.
Is the wider concept included?
Not initially. Other plan types, deeper automation and field integrations follow only after the quarterly surface-plan workflow is proven.
