Remote Sensing Coastal Change

We use remote-sensing technologies—such as aerial photography, satellite imagery, structure-from-motion (SfM) photogrammetry, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.

Satellite-Derived Shorelines for Five Groin Field Sites Across the United States Satellite-Derived Shorelines for Five Groin Field Sites Across the United States

This data release provides tidally corrected shoreline positions for five groin field sites of around the United States (Ventura, CA, Newport Beach, CA , Santa Monica, CA, Long Branch, NJ, Sandwich, MA). Both CSV files of tidally corrected shorelines and GeoJSON files of the region of interests (ROIs), transects, and reference shorelines are provided within respective zip files. Both...

Shoreline Change of Western Long Island, New York from Satellite Derived Shorelines Shoreline Change of Western Long Island, New York from Satellite Derived Shorelines

This data release contains tidally corrected shoreline positions for three sites of western Long Island, NY (Rockaway Peninsula, Long Beach, and Jones Beach Island). Both CSV files of tidally corrected shorelines and GeoJSON files of the region of interests (ROIs), transects, and reference shorelines are provided within respective zip files. Both file types are derived from CoastSeg v1.1...

Shoreline behavior at California groin fields from satellite-based measurements Shoreline behavior at California groin fields from satellite-based measurements

Satellite imagery has helped to provide decades of shoreline change data to coastal regions all over the world. Although shorelines around the globe have been armored with different types of coastal structures to try and protect beaches and properties from erosion, there are few studies of shoreline dynamics within structures such as groin fields using satellite images. Here we apply...

Comparisons of shoreline positions from satellite-derived and traditional field- and remote-sensing techniques Comparisons of shoreline positions from satellite-derived and traditional field- and remote-sensing techniques

Satellite-derived shorelines (SDS) have the potential to help researchers answer critical coastal science questions and support work to predict coastal change by filling in the spatial and temporal gaps present in current field-based and remote-sensing data collection methods. The U.S. Geological Survey conducted comparison analyses of traditionally sourced shorelines and SDS in diverse...

Shoreline seasonality of California’s beaches Shoreline seasonality of California’s beaches

We report on remote sensing techniques developed to characterize seasonal shoreline cycles from satellite-derived shoreline measurements. These techniques are applied to 22-yr of shoreline measurements for over 777 km of beach along California's 1,700-km coast, for which the general understanding is that shorelines exhibit winter-narrow and summer-recovery seasonality. We find that...

Shoreline change of western Long Island, New York, from satellite-derived shorelines Shoreline change of western Long Island, New York, from satellite-derived shorelines

Shoreline measurement techniques using satellite-derived imagery can provide decades of observations of shoreline change. Here we apply these techniques to the western south shore of Long Island, New York, which has three distinct beaches, Rockaway Peninsula, Long Beach, and Jones Beach Island, which are 18, 15, and 24 km in length, respectively. These beaches are recreation areas for...
