Large scale coastal mapping and inspection
The project, led by Royal Haskoning DHV and commissioned by the Environment Agency aimed to Survey and inspect large stretches existing flood defences between Lymington, Portsmouth and the Isle of White. The coastal and flood defences in this area consist of seawalls, breakwaters and revetments which all require regular maintenance and monitoring of these sensitive areas is crucial to extrapolate the coastal erosion rates and predict possible future shoreline positions.
As a key data capture partner for this project Future Aerial were required to deliver high-resolution models of the structures and surrounding salt marshes, achieving resolutions and accuracies far beyond that possible with traditional methods including manned aircraft LIDAR.
The method employed for this survey was a combination of high resolution, low level overlapping vertical and oblique photography to produce the models with the added value that the individual imagery can be used for close quarter, detailed asset inspection.
