Overview
Australia has long been amongst the premier countries providing free regional aeromagnetic data to promote geological mapping and mineral and groundwater resource exploration – a trend that is expanding worldwide.
The data is generally acquired for state or national geological surveys as parts of exploration initiatives with the concept that the greatest advantage is achieved from free availability of the data. This encourages exploration companies to evaluate the prospectivity of the areas, and also stimulates geological interpretations by universities, consultants and the geological surveys.
Traditionally the primary survey data is released, leaving end users to themselves enhance, model or invert it. This workshop explores the advantages of providing assistance in the form of value-add products, that can be supplied at only marginal expense compared to the primary acquisition and processing costs of the survey.
Availability of high quality data enhancements and analyses provides a much more convenient starting point for would-be users of the data who may lack the geophysical skills and/or software to develop these products themselves. This more effectively promotes use of the data as intended. We investigate a range of products that can either be supplied with new survey data releases, or which in countries with mature regional data coverage, can be supplied to stimulate renewed interest in previously surveyed areas.
To illustrate the value of value-add products, the workshop includes a world-first magnetic modelathon, in which participants will be provided with data from a newly-released regional survey, together with a suite of value-add products and temporary software licences with which to model features they select from the data. A web site and publication of the data will be developed from contributions of the workshop participants.
