MÉTODO

Cómo funciona.

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

01Step 1

Foliar water band depth

Foliar water absorption depth, taken against a dry-matter baseline so that leaf structure does not masquerade as moisture.

02Step 2

Stand-relative comparison

Moisture is compared within a stand and across dates, so every reading is judged against the ground it belongs to.

03Step 3

Structural correction

A canopy scattering model separates water content from canopy structure, so a dense crown does not read as a wet one.

04Step 4

Evaluability masking

Crown gaps where soil or rock dominates the pixel are marked, not averaged in.

Alcance

Needs continuous canopy cover. It reads crown moisture, compared within a stand rather than in absolute terms.
