Field Activity 14LGC01

Identifier 14LGC01
Purpose To provide ground truthing and Control for the Breton Island Bathymetry LiDAR survey scheduled to occur in early 2014
Location Breton Island National Wildlife Refuge, LA
Summary We will be providing support for LiDAR operations as well as collecting bathymetric data in order to ground truth recently developed Bathymetric LiDAR capabilities.
Info derived Elevation and Single Beam Bathymetry
Comments An Odom Echotrac and associacted 200 kHz transducer were used to collect bathymetric data.

Datasets compiled from multiple sources

Dataset name Equipment Description Dataset contact
baseline Ashtech Z-Xtreme DGPS A line shapefile parallel to, and seaward of, the Breton Island 1869-2014 shorelines. The baseline serves as a starting point for the Digital Shoreline Analysis System (DSAS) to cast transects. Joseph F Terrano
shorelines Ashtech Z-Xtreme DGPS Line shapefiles of mean high water shorelines derived from NOAA T-Sheets, aerial imagery, and Lidar, for Breton Island, LA, dating from 1869 to 2014. There are 14 shapefiles, one for each available date. Joseph F Terrano
transects Ashtech Z-Xtreme DGPS Line shapefiles of transects generated from the DSAS rate of change program. Transects were generated for the analysis time periods: long-term (1869–2014), long-term historic (1869–1950), post Mississippi River-Gulf Outlet (1950–2014), pre/post Hurricane Katrina (2004–2005), and recent (2005–2014). Rate of change statistics from each analysis are joined to the corresponding transects. There are 5 shapefiles, one for time period. Joseph F Terrano
