Tracklines Bathymetry
Trackline map overview for the 2014 Barrier Island Mapping geophysical surveys at Breton and Gosier Islands, Breton Island National Wildlife Refuge, Louisiana.
Figure 2. Trackline map overview for the 2014 Barrier Island Mapping geophysical surveys at Breton and Gosier Islands, Breton Island National Wildlife Refuge, Louisiana. Blue tracklines represent single-beam bathymetry, and green lines represent interferometric swath bathymetry. Island polygon is derived from 2014 U.S. Geological Survey lidar.

Figure 8. The 100-meter digital elevation model for the 2014 Barrier Island Mapping at Breton and Gosier Islands, Breton Island National Wildlife Refuge, Louisiana. Horizontal data are referenced to North American Vertical Datum of 1983 Universal Transverse Mercator (UTM) Zone 16 North and the vertical data are referenced to North American Vertical Datum 1988 with respect to GEOID09.
