District Prospectivity Ranking
A district-scale likelihood surface you can rank targets against, with the cross-validation scheme stated on the layer.
Regional likelihood scoring for hydrothermal systems, backed by leave-one-region-out cross-validation.
Open-pit iron ore operations. District scores rank ground like this before anyone commits to it.
WHAT THE SENSOR SEES
What this layer looks for.
The laboratory reference for each material, and what the sensor's band spacing captures of it. The shaded band marks the range the method reads.
WHAT IT FINDS
What it detects.
| Material | Typical setting | What can confuse it |
|---|---|---|
| Hydrothermal Core Complexes | Intrusive centers, volcanic calderas, and porphyry lithocaps | Extensive post-mineral volcanic cover |
| Structural Alteration Corridors | Regional faults, shear zones, and detachment systems | Quaternary colluvium in fault trenches |
METHOD
How it works.
Calibrated reflectance goes in, and every pixel is fitted against a public reference library.
District alteration clustering
Pulls spatial clusters of advanced argillic, phyllic and gossanous pixels out of contiguous scenes.
Leave-one-region-out calibration
Whole geological provinces are withheld during fitting, so a score cannot borrow its evidence from a neighbouring pixel in the same district.
Label permutation as a negative control
Discrimination is retested against randomised occurrence coordinates. A model that scores well on shuffled labels is measuring the sampling, not the ground.
Score generation with provenance
The output is a continuous district score carrying its model version, its input set and its interval. Expert-system features are deliberately kept out of it, so the two engines stay independent.
SPECIFICATIONS
What you get, and what it runs on.
Conditions it needs
Method and checks are documented in Axine Applied Spectroscopy Paper #1 · Section 5.1.
Scope
Ranks where to look first from surface evidence, not what a target holds.
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.
