LLyn Rhosddu Topographic Survey
This was a project where we combined an aerial survey with a ground based laser survey. Carried out for National Resources Wales, we were commissioned to survey an area of approximately 30 hectares from the air, and due to the nature of the land surrounding the lake, we also laser scanned from the ground to capture data below and beneath the tee canopy.
The aerial survey was carried out in one day using a multirotor and high resolution camera, with network rover GCPs. The laser scanning was done over 2 days and tied into the aerial data with GCPs. There was approximately 3 days of post processing involved.
DTM-Technologies, based in Anglesey, North Wales, specialise in digitally reproducing the world around us, accurately and at high resolution. We provide aerial survey, photography and film as well as land based scanning. Our deliverables are tailor-made for our client needs, interactive 3d applications, animations, point cloud and ‘meshes’. Survey grade data or simply for 3d visualisation purposes, we aim to provide whatever you require.
