Craig then wentis easier to interpret and is clearer, which makes it a useful tool for engineering and geotechnical studies, especially when developing infrastructure for renewable energies.Dr Ehsan Farahbakhsh (University of Sydney) presented at the April meeting, his talk was entitled The use of machine learning in processing remote sensing data for mineral exploration. Ehsan described how more innovative and efficient methods are required for processing different data types at each stage of mineral exploration as the number of newly discovered mineral deposits declines. As we know, mineral exploration involves many different data types; from the primary - mapping of lithological units, indicator minerals, alteration types and structures; to remote sensingsatellite and airborne data. This creates a high volume of data, and this is where machine learning methods provide a robust processing method to determine relationships between various Craig discussing the details and application of FTAN. components. Ehsan then provided a few examples that demonstrated the need to combine remote sending data with machine learning methods for mineral potential exploration maps.An invitation to attend NSW Branch meetings is extended to interstate and international visitors who happen to be in town at the time. Most talks are livestreamed on zoom and uploaded to ASEGs YouTube page later, so you also have the option to join us online. Meetings are generally held on the third Wednesday of each month from 17:30 at Club York. News, meetings notices, addresses and relevant contact details can be found at the NSW Branch website. All are welcome.Stephanie Kovach nswpresident@aseg.org.auQueenslandOn Tuesday April 26 the Qld ASEG Branch invited Mark Covington from Ehsan accepting a bottle of red as thanks from Bhavik (NSW Secretary).
