What does cadaster mean?
A cadaster is an official, comprehensive register of land within a jurisdiction, recording the extent, boundaries, value, and ownership of individual parcels. Maintained by governments — typically through surveying agencies — it serves as the authoritative basis for property taxation, land transfers, mortgage registration, and the resolution of boundary disputes. The word belongs to the technical vocabulary of surveying, law, and public administration, and appears most often in contexts such as "national cadaster" or "updating the cadaster." In American English the spelling is usually cadaster, while British English and many international bodies prefer cadastre. The concept has deep roots: rulers from antiquity onward kept land registers to assess taxes reliably, and monumental efforts such as Napoleon's early nineteenth-century French cadastre remain landmarks in administrative history. Today, as countries digitize their land records, the cadaster has taken on renewed importance in securing property rights, supporting development, and preventing fraud.
nounAn official public register or record of the extent, value, and ownership of land in a country or district, used as the basis for taxation and property administration.
- A public register of the quantity, value, and ownership of land, maintained chiefly for purposes of taxation and property administration.
"The surveyor updated the national cadaster after the new parcels were formally registered."
"Before any deed could be transferred, both parties had to consult the municipal cadaster to confirm the parcel boundaries."
"Modernizing the national cadaster with satellite imagery helped the government resolve decades-old disputes over land titles."
The plural is regular; however, because each jurisdiction typically maintains a single unified register, the plural usually appears when comparing systems across countries or regions.
"Comparing how different nations structure their cadasters reveals wide variation in how land rights are recorded."
Napoleon built one of history's most famous cadasters — a vast map-based land register so detailed it still underpins French property law today.

Etymology of cadaster
The word "cadaster" derives from French cadastre, which itself came from Italian catastro or catasto, meaning a register of landed property. The Italian term traces back to Late Latin capitastrum, a register of the capites or taxable heads of households, ultimately rooted in Latin caput, meaning head. This same Latin root gives us cognates such as catastrophe (via Greek katastrophē) and caste. The word entered English usage in the late seventeenth or early eighteenth century, largely in connection with European land-surveying and tax-assessment practices.
