Disasters, both natural and industrial are high profile and often-costly events. Flooding, hurricanes, earthquakes and oils spills, to list a few, can cause significant environmental and socio-economical damage. As a result, disasters both natural and industrial are high profile events that require an accurate understanding of the landscape pre- and post-event. 
A Rapid Response Aerial Survey, capturing high-resolution, geo-linked oblique imagery of areas threatened by disasters, be it built areas, linear assets such as powerlines, or environmentally sensitive areas such as coastlines and salt marshes, enables quick and accurate visualisation and analysis of the spatial extend of damage.Capturing imagery on a regular basis and incorporating it into ViSiVi provides efficient online access to baseline condition data. Comparisons of pre-impact and immediately post-disaster imagery can be made with ease. ViSiVi therefore acts as a crucial time-series tool for monitoring and analysing the short- and long-term impacts of disasters.
The clarity of the imagery captured on a Rapid Response Aerial Survey ensures that post-disaster relief and clean-up teams have accurate knowledge of what to expect, increasing efficient mobilisation and coordination between various teams. A further post-clean up geo-linked photographic survey can considerably alleviate any resulting media pressures. While the integration of GIS and CAD data sets to the geo-linked imagery helps personnel identify and map future potential hazards, in order to create effective mitigation strategies that will minimize economic losses and environmental damage.Offshore Oil companies have commissioned ViSiVi surveys to increase the speed at which early impact information and baseline data for areas under threat is gathered and available.
