[A general focus but very interesting and informative]
“James Morrison, head pilot and UAS ("Unmanned Aircraft System") lead at Ordnance Survey, discusses the use of drones in mapping and surveying. He shares examples of how drones were used to quickly assess landslips and update mapping in the Isle of Wight, as well as capture data for residential housing developments. James explains the different types of drones used by Ordnance Survey and their capabilities, including capturing imagery with centimeter-level accuracy…” #GIS#spatial#mapping#OSRapidMapping#engineeringgeology#remotsesensing#UAV#drone#survey#UK#England#UAS#aerial#usecase#efficiency#podcast @OS
Last week, we had a day trip to #Torquay but rather than drive or take the train, we decided on a different route. The first leg was a #cycle trip to #Exmouth, about 17 km, followed by a boat trip around the #Devon#coast. The weather was a bit changeable but there were only prospects of short showers.
On to a bit of #EngineeringGeology and #GeotechnicalEngineering, the erosion is a serious problem for any structures built on or near the coast and there is a mainline railway track on the route to London which runs along it on this stretch. #NetworkRail is busy trying to stabilize and strengthen the cliffs using #RockAnchor, #RockBolts and #meshing to retard the process. Here you can see workers #abseiling as part of their work.
