Topographic survey North-West Scotland

Case Study

Topographic survey North-West Scotland

Cyberhawk was asked by a major utility company to provide topographic survey data and high-resolution aerial photography of a 62 Hectare area in the north-west of Scotland. The site comprised of an area of open farmland with a cliff running along the east side. There was no safe ground access to the cliffs or foreshore so remote aerial data acquisition was the ideal method to survey the area.

Cyberhawk deployed a two man team of a land surveyor and pilot to survey the site using a combination of fixed-wing and multi-rotor UAVs alongside traditional land survey equipment. The farmland was surveyed using the fixed wing UAV and the cliffs were surveyed using the multi-rotor UAV. Traditional survey techniques were used to observe ground control markers around the site. Natural marks were remotely observed on the foreshore using a direct-reflex total station instrument. The survey of the coastline was undertaken at low tide to ensure the maximum amount of data could be acquired.

Cyberhawk’s rigorous health and safety and flight-planning procedures were approved in advance by the site owner and the client, along with Cyberhawk, worked closely with local Air Traffic Control given the close proximity of an airport.

A Digital Elevation Model (DEM), detailed Orthophoto (at 3cm ground resolution), 360 degree spherical photos and point-cloud data were provided. Cyberhawk’s data was used by the client to design the layout of the proposed development and to assist with geological analysis.
