Why LINZ uses open source software
summary
Land Information New Zealand traces open source use to the 1990s and pivots from an expensive Oracle/Esri stack after a $160M modernization that struggles with Informix and vendor delays. Postgres/PostGIS becomes the PostGIS as gateway for parcel topology and multi‑million row queries, with community maillists resolving index bugs overnight. The org runs GDAL, PROJ, QGIS and Ubuntu across many systems, funds WKT/GDAL work, staffs a core PostGIS committer on staff, and rebuilds Landonline under the STEP program to keep control and cut procurement costs.
