6 Geocoding and Location Data Free Online FlashCards

What does geocoding do?

Geocoding converts a place description, usually a postal address, into geographic coordinates such as latitude and longitude.

Does a geocoded match prove an address is valid and exact?

No. A geocoded result is an estimate based on reference data and matching methods; it does not prove the address is valid or pinpoint a building.

Why retain each address record’s unique ID?

Keep each record’s unique ID so geocoding results can be joined back to the original data.

What is an interpolated geocoded position?

An interpolated position is estimated along a road segment between known address locations; it may be near the address without marking its building or entrance.

What geocoding details support auditing and repeatability?

Retain the original input, matched address, coordinates, result type, provider, and relevant dataset or benchmark version to support auditing and repeatability.

What is reverse geocoding?

Reverse geocoding uses coordinates to find a nearby human-readable address.

Why separate address components before geocoding?

Separating components such as house number, street, unit, city, region, postal code, and country makes the input clearer and easier to process consistently.

Why keep both original and standardized addresses?

Retaining both versions makes corrections traceable and preserves the original input for comparison.

How does locality information improve address matching?

Locality details such as city, state or province, and country help distinguish repeated or similar street names and addresses.

Can match scores be compared directly across geocoding providers?

Match scores and labels are service-specific, so they should not be assumed directly comparable across providers.

What does a no-match result establish?

A no-match result means the service could not locate the address in its reference data; it does not by itself prove the address does not exist.

What does a partial geocoding match indicate?

A partial match means only part of the request was resolved. It can signal incomplete or misspelled input, or multiple possible places, and may need better input or manual review.
