• Box roles: RBox role (What is this?)

The lower bound of this regulatory overlay in a vertical dimension (altitude, depth, elevation), expressed as a ScalarQuantity with unit (QUDT) and reference frame. Optional: absent for purely 2D overlays. Frame-relative per Principle 11 (e.g. altitude above MSL, flight level, depth below sea level).

Structure

Property shape: object property; gmeow:RegulatoryOverlay -> gmeow:ScalarQuantity

Practical Pattern

Use gmeow:overlayLowerBound from gmeow:RegulatoryOverlay to gmeow:ScalarQuantity when the relationship itself belongs in the native GMEOW graph.

Common Companion Terms

gmeow:RegulatoryOverlay, gmeow:ScalarQuantity

Usage Advice

Use when

• Use for the lower vertical bound of an overlay (altitude/depth/elevation) as a frame-relative ScalarQuantity.

Avoid when

• Avoid for purely 2D overlays (leave absent) and avoid a bare number without unit and vertical frame (Principle 11).

How to use

• Point gmeow:overlayLowerBound at a ScalarQuantity with QUDT unit in an altitude/depth reference frame; pair with gmeow:overlayUpperBound.

Examples

• ex:ov gmeow:overlayLowerBound ex:fl100.
