The selected measurement is vertical relative to a defined base or reference level.
This is an observed measurement. The displayed precision follows the cited reference and should not be read as infinite accuracy.
Vastoscope compares the SI value in metres for this current antenna height. A ratio is mathematically valid as a linear span, while the interface identifies when the two selected definitions differ.
Familiar scale bridges
These anchors are selected by logarithmic proximity from familiar human, engineered, planetary and cosmic references.

A full-size school bus, useful as a measuring stick for dinosaurs, whales and buildings.
A representative adult human — the central reference point for moving both inward and outward.
Evidence trail
Vastoscope keeps the displayed number separate from its measurement type and certainty. Representative and model-dependent values are intentionally labelled instead of presented as exact edges.
