NZ Airborne Gravity Bouguer Anomalies at Ground Surface (2013-2014)
The 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.
This dataset provides a 1 arc minute raster image of the Bouguer anomalies, which have been downward continued to the ground surface (McCubbine et al, 2017).
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.

- Statement
-
This dataset is comprised of the downward continued Bouguer anomalies from the national airborne gravity survey. The downward continued process was completed using least squares collocation, a process which grids the dataset while reducing the data observed at elevation to the ground surface.
The airborne survey was observed over a period of eight months, over two campaigns: August – October 2013, and February – June 2014.
