Satellite technology currently offers medium-resolution (10 to 30 meters) images at high temporal frequency (~5 days between images) at any location in the world. Publicly available satellite imagery spanning the last three decades has the potential to provide coastal engineers, managers, and scientists with detailed information on past shoreline changes.
This presentation will introduce a new open-source shoreline mapping toolbox (CoastSat) that enables users to obtain time-series of shoreline change at any sandy coastline worldwide from 30+ years (and growing) of publicly available satellite imagery.
An analysis comparing satellite-derived shoreline position to ground-truth data at 5 diverse sites reveals the temporal scales of shoreline variability (e.g., over the time scales of a single storm event, beach rotation, seasonal changes, long-term erosion/accretion trends, and engineering interventions) that can be resolved using satellite imagery. This analysis informs a discussion of the applicability and limitations of satellite remote sensing in the field of coastal sciences and engineering
