Coasts and waterways are constantly shifting due to erosion, varying weather conditions and unauthorised anthropogenic activities. Consequentially, ViSiVi aerial photography surveys have been utilised on numerous marine, river and canal projects around the world to provide quick, up-to-date, visual access to otherwise remote areas.
ViSiVi has been used for flood risk and mitigation assessments in areas of higher risk and for flood damage evidence after incidents occur. The tool also delivers a clear understanding of river boundary condition and access points for the river authorities, allowing them to identify whether river bank usage complies with agreements with landowners. A virtual-site-visit of rivers and canals is useful for pilot studies and expansion feasibility studies.
Coastal zone management is significantly aided with access to ViSiVi’s high-resolution imagery as the oblique view enables engineers to closely examine the elevation and undulations of cliff faces along the coastline.
In the UK, ViSiVi formed a major part of the FutureCoasts project, enabling all bodies with influence on coastal usage a view of the entire coast, while also providing a medium from which to compile their suggestions and concerns. Further afield in Georgia, Azerbaijan and Kuwait, the offshore oil companies gathering baseline environmental data have commissioned a number of coastal studies, while wind farm projects have found coastal imagery vital for landfall assessments and cable routing.
