elevation

CURIE: gmeow:elevation
IRI: https://blackcatinformatics.ca/gmeow/elevation
Category: property
Defined by: gmeow:slices/places
Box roles: RBox role (What is this?)

Elevation above sea level in metres.

Structure

Property shape: datatype property; gmeow:GeoCoordinates -> xsd:decimal

Practical Pattern

Use gmeow:elevation from gmeow:GeoCoordinates to xsd:decimal when the relationship itself belongs in the native GMEOW graph.

Usage Advice

Use when

Use for elevation above sea level in metres on a GeoCoordinates point.

Avoid when

Avoid for a frame-relative vertical bound on an overlay (use gmeow:overlayLowerBound / gmeow:overlayUpperBound with a ScalarQuantity) and avoid for celestial epoch.

How to use

Add gmeow:elevation alongside gmeow:latitude / gmeow:longitude; for explicit vertical datums use the altitude/depth reference frames.

Examples

ex:pt gmeow:elevation 47.0.
