Abstract

Mapping assessment of coastal erosion using LiDAR and optical data
Track: Lidar and 3D Mapping
Authors: Patrick Collins, Susan Parks

The study of coastal management includes applications such as severe storm vulnerability assessments, sea-level rise monitoring, and coastal erosion analysis.

Using a combination of lower resolution optical data, such as Landsat imagery, combined with precise LiDAR data, can help with the study of coastal erosion. Using low resolution optical data allows for a quick and inexpensive way to obtain a landscape-level overview of coastline changes, and helps to identify areas of concern that will require a more in-depth study. LiDAR data can be used to measure the effects on beach changes and cliff erosion along coastlines, due to elevated sea levels from large weather events.

This presentation will discuss how LiDAR data can be used in combination with optical data to map and assess erosion occurring in coastal areas.
