Cognised existence: An address is a structured spatial identifier that connects a human activity — dwelling, business, service — to a point in geographic space. It is a universal join key in many geospatial data ecosystems.
Question: Where is a property located by its official address?
What is an Address?
An address is not a coordinate. It is a layered set of identifiers (street name, house number, floor, door) that can collapse to one or more coordinate representations depending on purpose. In most data ecosystems, many registries reference addresses. Understanding the join chain from address entities to geometry is fundamental.
Realisations
Instead of hardcoding implementation schemas here, SPHERE separates semantic meaning from dataset implementation. The realisations are listed in priority order:
- DAR Realisation (administrative_register)
- OSM Realisation (volunteered)
