What Is a Geocoding Confidence Score?

A geocoding confidence score is provider-specific metadata about how strongly a returned candidate matches a query; it is not a universal probability of correctness or a direct measure of positional accuracy.

Geocoding vs Reverse Geocoding

Forward geocoding turns a textual place or address query into candidate geographic locations; reverse geocoding starts from coordinates and returns nearby place or address context.

Geocoding vs Place-Name Matching

Geocoding assigns or retrieves geographic locations from text, while place-name matching resolves whether names in different records refer to the same geographic entity.

What Is a Geographic Identifier?

A geographic identifier is a code or identifier used to refer to a geographic entity within a defined namespace; unlike a display name, it is intended to support stable identity and joins.

Why Place Names Are Ambiguous

Place names are ambiguous because many places share names, one place can have several names, names change over time, and the same label can refer to different geographic feature types or extents.

Why Stable Geographic Codes Matter

Stable geographic codes let datasets refer to the same places even when names, spellings and display labels change, making joins, version tracking and interoperability more reliable.
