Provenance

This ontology was made within the IDN's ID Catalogue project 2021 - 2023.

Description

This ontology extends the geometry representation Knowledge Graph elements used by GeoSPARQL 1.1 to cater for narrations of location and qualified geometries. Collections of qualified geometries allow for modelling options such as "fuzzy" geometries.
