Geological and Geotechnical Mapping using LiDAR - March 15th

The Western Regional Group of GS would like to invite you to a Geological Society evening lecture, ‘Geological and Geotechnical Mapping using LiDAR’, presented by Adrian Wilkinson of QuarryDesign Ltd.  This event is taking place on Tuesday 15th March.   
Detailed geological and geotechnical data can sometimes be hazardous to obtain, particularly in areas of instability such as quarry faces or landslips. Traditionally, a quarry survey would have been undertaken using differential GPS or by total-station surveying, with more detailed discontinuity data collection being undertaken at distance by direct-reflective techniques or at the rock face using compass clinometers.  However, recent significant improvements in LiDAR (light detection and ranging) surveying means it is now possible to use LiDAR to obtain data at faster speeds and over a greater distances, in the order of 3,000m from the rock face.
Adrian will demonstrate how long-range high definition LiDAR techniques can be used as part of an integrated approach to geological and geotechnical mapping, allowing more accurate data to be collected both quicker, and more safely. Furthermore, the enhanced survey detail obtained using LiDAR can be combined with advances in computer processing power and software engineering to allow more complex and realistic simulations and potential hazards, such as rockfalls, to be undertaken.
Adrian is Geotechnical Director at QuarryDesign and is an aggregates geologist with over 17 years experience within the quarrying industry undertaking site investigations and producing quarry development plans.  He is a Chartered Geologist and Fellow of The Geological Society of London, a Member of the European Federation of Geologists, a Member of the Institute of Quarrying and a Member of the Irish Mining and Quarrying Society.  QuarryDesign and its associated consultancy QuarryPlan Ltd provide geological, geotechnical, mineral planning and estates management advice to the quarrying industry.
The lecture will start at 6.30pm, but please feel free to come and have a few sandwiches and a chat with colleagues from 6.00pm.  There is no charge for the event and non members are welcome.  The lecture will be held in the S H Reynolds Lecture Theatre (Room G25), Department of Earth Sciences, University of Bristol, Wills Memorial Building, Queen's Road, Bristol BS8 1RJ.
