Description: The Study Area Contours feature class is an interpolated line representation of a survey dataset (e.g., mulitbeam, single beam, LiDAR, side scan, etc.). This data is a derived product from either raw survey point data or a rasterized version. Because this is a derivative product, contours represent an estimation of the actual bathymetric surface. This dataset contains attributes including latitude, longitude, elevation (negative for below sea level), and potentially a backscatter/intensity value. Include survey specific metadata delivered from the contractor into Supplemental Information.
