We link Earth observation to mine rehabilitation success criteria and to the continuous monitoring of mine sites across the life of a mine, so that rehabilitation success is tracked over time and action taken when needed.
Mining leaves a footprint that must be managed long after extraction ends. Closure and rehabilitation are regulated obligations, and the land must be monitored across the life of a mine: disturbed area, structures, landforms and the progress of rehabilitation.
Earth observation fills the gaps between field visits with a continuous picture: whole site, frequent revisits, sensor-level detail, and trajectories that run for years.
Our mission is to put Earth observation to work beside the field survey,
as clear, repeatable, verifiable evidence of the state of the land.
Each completion criterion in the site's rehabilitation management plan that can be measured from orbit, or reliably approximated, is tracked over time.
Ground cover against the plan's threshold illustrates the approach: one published target, one measurement, one verdict with its margin.
The land is watched as new observations arrive. A change is detected against the land's own history, dated and characterised, and raised for action when it matters.
For example, a patch that loses cover while its neighbours hold is raised for a look on the ground; a dry spell across the whole site is noted, not raised as a local alert.
Open satellite records, public agency datasets, airborne surveys and the site's plans and records. Commercial imagery when a criterion calls for finer detail.
Each layer follows a written method statement, open to review and applied consistently at every site, year after year. Results can be reproduced, and their uncertainty and limits are stated.
Checked against independent records, and built to be verified on the ground. Every figure can be traced to the observation behind it.
New South Wales publishes its rehabilitation record as open spatial data: every rehabilitated area mapped, with its phase, year after year, on the state's SEED platform, together with each site's published completion criteria. Satellite observations can be laid over that record directly, area by area.
The first site study was built on it, and New South Wales is where the first pilots will run.
We are selecting a few pilot sites in New South Wales.
If you have a site in mind, we would be glad to hear from you.
If your site is elsewhere, we will tell you what can be done with its records and the satellite archive.
One site, both pillars, several years of record: the methods, the results and their limits, in one document.
