Mine Footprint & Disturbance
Open pits, waste rock dumps and tailings boundaries, tracked across dates on a common grid.
Multi-temporal surface disturbance, tailings boundaries and waste rock footprints, measured between dates.
Open-cast workings. Footprint boundaries are differenced between dates.
WHAT IT FINDS
What it detects.
| Material | Typical setting | What can confuse it |
|---|---|---|
| Mining Surface Disturbance Footprint | Open-pit and underground mine sites globally | Natural seasonal vegetation dieback in surrounding wildlands |
METHOD
How it works.
Calibrated reflectance goes in, and every pixel is fitted against a public reference library.
Pairing the two dates
Both scenes are placed on a common grid. Differencing across sensors is refused, and so is differencing a result from one engine against a result from another.
Differencing with the offset exposed
Raw differencing on layers that carry an absolute scale on both dates. The scene-wide median offset is shown and can be removed, so a seasonal brightness shift is visible as such rather than mistaken for new ground.
Segmentation into facility classes
Disturbance is split into pit, waste rock, ponds and infrastructure by shape and spectrum together.
Overlay against the permitted boundary
Polygons are intersected with the boundary you supply and reported inside and outside, in km² to one decimal. An all-empty difference raises rather than reporting that nothing changed.
SPECIFICATIONS
What you get, and what it runs on.
Conditions it needs
Method and checks are documented in Axine Applied Spectroscopy Paper #1 · Section 10.2.
Scope
Surface disturbance only. Underground workings and wall stability sit outside what it reaches.
RUN IT OVER YOUR GROUND
Run this layer over your own area.
Order processing over your area of interest, or a tasked capture where the archive has nothing usable. Imagery access is never charged for: a plan buys the models.
COMPLEMENTARY ANALYTICS
Related layers.
Acid Drainage Screening
Screening for precipitate coatings along discharge channels, with a ferric floor gating the read.
Tailings Dam Stability & Seepage
Monitors moisture and sulfate weathering on exposed embankment faces, differenced across dates.
Pipeline Corridor Terrain Stability
Tracks swelling clays and moisture along a corridor, so crews go where the ground actually moved.
