I have come across this issue in another language. I think England does not differentiate between land registers and property registers, while Italy requires the land as well as the property deed to be registered through separate registers/bodies.

"THE CATASTO
In Italy, the Catasto (Cadaster) is the land registry which contains graphical, census and administrative data on properties throughout most of the country¹. The Catasto is divided into two parts: one covers urban properties, the other covers rural land. The Catasto is used primarily for tax purposes.

THE DEEDS REGISTRY
A separate deeds registry, the banca dati ipotecaria, contains information on property ownership, indicating who has or had legal rights to a property, including mortgage liens and other limitations on ownership. Somewhat confusingly this registry is often referred to by a series of alternative names:
registri Immobiliari – “PROPERTY REGISTRIES”, derived from when separate manual registries were maintained across the country.

I agree with Paul O'B's land surveys, but have never thought that - contrary to UK land lawyers referring to civil-law 'cadastral' systems and certain ProZ recondites - cadastre cadaster or even Land Registry (Garzanti) meant much. In fact, in 4 decades of UK land conveyancing and index map searches, I have never encountered the term in 'English'.

Ireland: 'Ordnance Survey Ireland is the Irish State's National Mapping Agency, essential to the infrastructural development of the country.'

UK: an Index Map search is based on the Ordnance Survey and is routinely made to see whether a propert (land + building) has been land- regd.

seems to be just land registry in English
