description: >-
|
|
Geographic coordinates representing a point location with latitude and longitude
|
|
(and optional precision). Used to locate heritage custodians, events, and other
|
|
geographically situated entities.
|
|
|
|
Ontology mapping rationale:
|
|
- class_uri is geo:Point from WGS84 vocabulary, the standard for representing
|
|
points on Earth with lat/long coordinates
|
|
- close_mappings includes sf:Point from OGC Simple Features as an alternative
|
|
geometry representation
|
|
- related_mappings includes geo:SpatialThing (superclass) and schema:GeoCoordinates
|
|
as Schema.org's coordinate representation
|
|
class_uri: geo:Point
