Finding and accessing MGI

Finding and accessing data facilitates its reuse.

In New Zealand, MGI is collected by various public and private organisations. The NZMGI-WG aims to increase the findability and accessibility of MGI.

National MGI Inventory

The development of a National MGI inventory is the first step in improving discovery of NZ’s MGI. NZ marine data owners are encouraged to contribute to the National MGI Inventory. The preliminary results of this work are available through catalogue.data.govt.nz.

Support in undertaking a Marine Geospatial Stocktake and contributing to the National MGI Inventory is available. The NZMGI-WG has produced a guidance document:

MGI Portals

The NZ MGI Data Portal study was undertaken to :

  1. support data users in finding, accessing and reusing NZ MGI
  2. encourage data custodians to share the MGI they hold
