Coastal Drone Survey
In December 2017 we were asked by the National Trust use aerial photography in Cornwall to do a drone survey of the cliffs near Godrevy Lighthouse.
This part of the Cornish coastline at the north end of St Ives bay has been battered by the recent storms that hit Cornwall. This part of the coastline was subject to extreme weather conditions at the end of 2017, so visitor access and public safety was also a concern.
We were asked by the National Trust for use the drone survey to film the cliff edge area with the drone dropping below cliff level to video the condition of the cliffs.
This will help the National Trust to determine how undercut the area is assess the damage to the coastal paths and to make decisions about the damage, with the feasibility of installing a low post and rail fence on the cliff edges in future.
The specific area is on the eastern side of St Ives Bay, which faces the Atlantic Ocean. It is popular with both the surfing community and walkers. It is part owned by the National Trust, and offshore on Godrevy Island is a lighthouse maintained by Trinity House.
Godrevy Head lies within the Cornwall Area of Outstanding Natural Beauty (AONB) and the South West Coast Path runs around the whole promontory. There are several public car parks on the western side where the National Trust owns and operates a café.
The Site is roughly square in shape and faces north into the Atlantic occupying an area of approximately 1-square-mile. The 340 acres and 5 miles of coastline was donated to the National Trust.
Godrevy Head has some of the best coastal heathland in Cornwall, with many species of plant, animal and insect life. Part of the headland, along with the coast to the east, is designated as part of the Godrevy Head to St Agnes SSSI (Site of Special Scientific Interest).
The images were take with our 20megapixel drone camera which gave the client large high definition images. The large images allowed them to zoom in on all of the details of the rock face and cliff erosion.
The image below from the drone survey established the extent of the erosion and how the sea was affecting the zawn.
Godrevy to Hell’s Mouth Coastal Walk
Here is what the National Trust says about the walk –
Exhilarating cliff-top pathways and glorious ocean views. This route takes you around Godrevy headland to the dramatic Hell’s Mouth and back again, taking in the wonderful heathland of the Knavocks.
Head out through the dunes and breathe in the ocean views
Learn fascinating local history of shipwrecks and pirates, see if you can spot dolphins, seals and basking sharks in the Cornish waters, and enjoy the wildlife on the colourful heathland.
It is one of the most spectacular parts of the beautiful Cornish coastline and Drone Photography Services were very happy to use our drones to provide aerial drone photography to help the National Trust preserve and maintain this part of the South West coastal path.
