NZ Airborne Gravity Flight Lines at Elevation (2013-2014)

Abstract

**Introduction**
This dataset provides gravity observations, reductions and metadata for New Zealand’s national airborne gravity survey at flight elevation. A full description of each field in this dataset is available in the accompanying pdf [NZ Airborne Gravity Flight Lines at Elevation (2013-2014) Description](https://data.linz.govt.nz/document/1825).

**Description**
New Zealand’s national airborne gravity dataset is comprised of more than 50,000 linear km of flight observations, covering the three main islands of New Zealand and up to 10km offshore.

Gravity observations can be used to compute gravity anomalies: differences between measured gravity and an ellipsoidal model of the Earth’s gravity field. Gravity anomalies correspond to un-modelled density variations within the Earth’s crust and upper mantle. They are used to investigate concealed geological structures and for quasigeoid modelling.

The national airborne gravity dataset was collected as a joint project between Land Information New Zealand (LINZ), GNS Science (GNS) and Victoria University of Wellington (VUW). The airborne survey was completed in a total of eight months, over two campaigns: August – October 2013, and February – June 2014.

**Users may also be interested raster layers created for each of the free-Air and Bouguer Anomalies which have been downward continued to ground surface** [NZ Airborne Gravity Free-Air Anomalies at Ground Surface (2013-2014)](https://data.linz.govt.nz/layer/3532) and [NZ Airborne Gravity Bouguer Anomalies at Ground Surface (2013-2014)](https://data.linz.govt.nz/layer/3530).

Purpose

Purpose of this dataset is to supply the national airborne gravity dataset for use in geophysical research and mapping.
