What is addresses and names data?
Features of addresses and names data
Enhanced mapping and analysis
Visualise and analyse named locations alongside detailed address data, including postal status, construction phase, and lifecycle tracking.
Islands data

Additional language support
Identify places with multiple names, and with an alternative language name, including English, Welsh, and Scots/Gaelic.
