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 totalstation 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.
In this talk, Adrian Wilkinson demonstrates 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.
Entry is free, and refreshments will be available from 5:30pm.
5:30 for 6pm
