Mapping 75km of Cornish coastline, from the air

Large-scale coastal data capture for geological assessments.

Cormac was tasked with delivering high-accuracy survey models across a vast stretch of Cornish coastline, covering cliff faces, foreshore and inaccessible terrain to support geological and geotechnical assessments for the mineral extraction sector.

The deliverables had to be precise enough to underpin downstream engineering decisions, and broad enough to give a continuous picture of the entire site.

A coastline-scale capture, in numbers.

Over roughly sixty processing days, two Cormac operatives delivered a survey of unprecedented scope, covering terrain that on-foot teams simply could not safely or practically reach.

Hardware

The DJI M300 RTK and M400, flown with the Zenmuse P1 and H30T, gave Cormac the endurance, payload flexibility and image quality required for surveygrade output at coastal scale.
