This zip archive contains processed x,y,z data points for the interferometric swath bathymetry data collected in July 2013 (13BIM02) and August (13BIM07) around the Chandeleur Islands, Louisiana.
NOTE: These data are scientific in nature and are not to be used for navigation. Any use of trade names is for descriptive purposes only and does not imply endorsement by the U.S. Government. The processed swath data are provided as an ASCII x,y,z point data file. These values are not the individual soundings but are the exported BASE (Bathymetry with Associated Statistical Error) surface at 5-meter spatial distances with associated CUBE (Combined Uncertainty and Bathymetry Estimator) sample surface created from the edited soundings dataset. These are considered interpolated samples in which one value represents all soundings within a five-meter node, weighted by uncertainty and proximity, giving the final value as a data sample within the specific grid cell. No manual editing has been applied: no erroneous point removal, interpretation, or validation has been done beyond this point.
Are there legal restrictions on access or use of the data?
Use_Constraints:The U.S. Geological Survey requests that it be referenced as the originator of this dataset in any future products or research derived from these data. These data should not be used for navigational purposes.
