LDT utilizes modern technology to conduct its high-resolution aerial mapping surveys. By employing a survey grade remotely piloted aircraft, otherwise known as a drone, we are able to efficiently survey large areas. Our process, known as Photogrammetry, involves recording a series of images and establishing precise ground control points (GCP’s) to ensure accurate data that can be referenced to Ordnance Survey OSGB coordinates. To further enhance the results, we supplement our aerial survey with a Total Station Survey, which allows us to record specific points of interest on the pylons and conductor catenary’s. These steps enable us to produce highly accurate Sag and Swing drawings that detail the precise locations of conductors and structures, strictly adhering to industry guidance such as ENA 43-8 and HSE GS6. At LDT, we always aim to provide professionals with the highest quality services.
