West Coast aeromagnetic survey data available

Publish date: 18 July 2013

Aeromagnetic survey data of the West Coast region of the South Island will soon be available.

Data packs can be ordered now for delivery in early August.

Between February 2011 and March 2013, approximately 16,000 square kilometres of the West Coast was surveyed and 91,722 line kilometres of data collected.

Commissioned by New Zealand Petroleum & Minerals, the survey was undertaken by Australian firm Thomson Aviation using local helicopters. The flight line direction was 110-290 degrees; and flight line spacing 200 metres with tie line spacing at two kilometres.

The survey provides valuable information on the subsurface geology of the West Coast. All land listed under Schedule 4 of the Crown Minerals Act 1991 as unavailable for mining is excluded from the survey data.

The data also has a wide range of applications in fields such as geological mapping, geothermal exploration, forestry, agriculture, horticulture, geological hazard assessment, and engineering and construction investigations.
