Visualization of Terrestrial Change of Barrier Islands Using Multi-Temporal Digital Elevation Model


Under effects of sea-level rise and storms, the terrain of barrier islands is subjet to both long- and short-term changes. Since there are many civil and military infrastructures on barrier islands, for long-term resources and engineering management, it is important to understand long-term terrestrial changes of barrier islands under sea-level rise. Visualization of terrestrial changes based on the Digital Elevation Model (DEM) is a vital tool to acilitate the scientific understanding.
