From this image product, coastal features and hazards such as the shoreline position as it moves up and down the beach with the tide, the presence and shape of offshore sandbars, and the occurrence of rip currents can be extracted. Changes in all of these features through time provide valuable insight into the dynamic nature of coastal environments."

Video observations of the coast can be used to monitor a range of coastal processes, for example changes in the shoreline position, both seasonally and due to long-term effects such as sea-level rise, and instances of beach and dune erosion during extreme storm events. These observations are used to evaluate and develop computer models for predicting water levels at the shoreline driven by surge and waves, which are used by the USGS to identify the vulnerability of our coasts to flooding and erosion during storm events."

Images and videos taken from cameras are useful for observing current coastal conditions and for comparing how conditions along the coast change through time. This includes, for example, tracking increasing water levels during a storm and monitoring the potential impacts of waves colliding with protective sand dunes."
