Data collection and processing was managed by private contractor, Dewberry. The survey limits and methods were determined by RSD. This topo-bathy lidar survey was acquired in accordance with the requirements defined in the National Geodetic Survey (NGS) Sandy Supplemental Statement of Work Volume 4. Please see the NGS Remote Sensing Division (RSD) DR/DAPR report for any deviations from this requirement. W00330 has been designated a sub-region of W00300 extending from Norfolk, VA to Buck Island Bay. The data set from W00300 contains outer coast and inlet data from Winyah Bay, SC to Norfolk, VA. This is a subset of a larger Post Hurricane Sandy topo-bathy lidar data set that extends from South Carolina to New York. The entire data set spans 140 blocks and has been broken down into four sections for submission to the Office of Coast Survey (OCS). This data set contains block 01 through block 60, as outlined in Figure 1. See Appendix A. Bathymetric Coverage for grid coverage by block. The entire data set can be found on the NOAA Data Access Viewer.There were no products created for this survey.All survey systems and methods utilized during this survey were as described in DR_DAPR_VA1408_W00300_signed.Soundings were reduced to Mean Lower Low Water (MLLW) using VDATUM. During evaluation several regions of significant change were detected around inlets and capes and submitted to the Atlantic Hydrographic Brach for consideration as Danger to Navigation (DtoN). The Branch analyzed the data and submitted 59 shoal soundings as DtoNs to MCD. The report created by the Branch, W00300_DtoN_#1, has been included in this data submission. As stated in the report, final sounding selection will be performed during HCell compilation. Figure 6 and 7 highlight two areas of significant change included in the DtoN submission.NOAA Remote Sensing Divisionhttps://coast.noaa.gov/dataviewer/#/lidar/search/where:ID=4967The dataset was reviewed for dangers to navigation, areas of significant bathymetric cover related to chart scale, and areas of significant shoreline change that may warrant return by a hydrographic platform. Survey scale soundings generated from the three meter surface were used to evaluate differences with the chart.This survey does meet charting specifications and is adequate to supersede prior data.All records from RSD are included with the JHC IOCM products for final review and processing to the Processing Branch. The survey data meets or exceeds requirements for reconnaissance lidar data as set forth in the NOS Hydrographic Surveys and Specifications Deliverables Manual, Field Procedures Manual, Standing and Letter Instructions, and all HSD Technical Directives. These data are adequate to supersede charted data in their common areas. This survey is complete and no additional work is required with the exception of deficiencies noted in the Survey Summary Report.OSD-RSD-15W00330VirginiaCoastal Virginia Beach, VANorfolk, VA to Buck Island Bay10000RiegalVQ-820GLIDARNorth American Datum 1983Mean Lower Low WaterVDatumNAD83 - UTM Zone 18NNOAA Remote Sensing Division2013-11-252014-07-20Michael Aslaksen, Chief, NOAA Remote Sensing Division2016-08-24
