Huella Minera y Perturbación

Tajos abiertos, botaderos de roca estéril y límites de relaves, seguidos entre fechas sobre una malla común.

Perturbación superficial multitemporal, límites de relaves y huellas de botaderos, medidos entre fechas.

In view

Open-cast workings. Footprint boundaries are differenced between dates.

MÉTODO

Cómo funciona.

Entra reflectancia calibrada, y cada píxel se ajusta contra una biblioteca pública de referencia.

01Step 1

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.

02Step 2

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.

03Step 3

Segmentation into facility classes

Disturbance is split into pit, waste rock, ponds and infrastructure by shape and spectrum together.

04Step 4

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.
