If you have been using LINZ title and survey data for some time, you may sometimes need to refer to our reference material about our legacy data systems.

Bulk Data Extract

LINZ’s former Bulk Data Extract service provided a monthly extract of tables from Landonline, delivered to customer on a DVD. The Bulk Data Extract service was discontinued in 2015 and all data is now available from the Full Landonline Dataset on the LINZ Data Service. 

Digital Cadastral Database

From the mid-1980’s, cadastral record maps were digitized to form the Digital Cadastral Database (DCDB). This was LINZ’s first system to contain digitised cadastral records, and was superseded by Landonline. From time to time, LINZ customers interested in data from Landonline need to refer to information about the DCDB to understand the lineage and context of Landonline data.

  • Otago - 30 March 2000
