Methods and limits

What the model shows—and what it cannot.

Mayon is rendered at true scale using a locally baked terrain and imagery base. Historical scenes, interior forms, and hazard layers are interpretive teaching aids with different evidentiary status.

Observed / measured

Terrain uses NASA SRTM elevation in a 52 km local grid. Satellite imagery is a local Esri World Imagery drape.

Historical / reconstructed

Story scenes condense complex events into short educational chapters. They are not complete reconstructions.

Inferred / illustrative

Subsurface plumbing and hazard routes make scientific ideas legible; they are not direct images, predictions, or evacuation maps.
