Single-Beam Bathymetry Sounding Data of Cape Canaveral, Florida, (2014) gridded in ESRI GRID format

The Cape Canaveral Coastal System (CCCS) is a prominent feature along the Southeast U.S. coastline and is the only large cape south of Cape Fear, North Carolina. Most of the CCCS lies within the Merritt Island National Wildlife Refuge and included in its boundaries are the Cape Canaveral Air Force Station (CCAFS), NASA’s Kennedy Space Center (KSC), and a large portion of Canaveral National Seashore. The actual promontory of the modern cape falls within the jurisdictional boundaries of the CCAFS. These various agencies have ongoing concerns related to erosion hazards and vulnerability of the system including critical infrastructure, habitats, and recreational and cultural resources. The USGS conducted a bathymetric mapping survey August 18-20, 2014, in the Atlantic Ocean offshore of Cape Canaveral, Florida (USGS Field Activity Number 2014-324-FA). The study area covered an area extending south from Port Canaveral, Florida, to the northern end of the KSC property and from the shoreline to about 2.5 km offshore. Bathymetric data were collected with single-beam sonar- and lidar-based systems. Two jet skis and a 17-ft outboard motor boat equipped with the USGS SANDS hydrographic system collected precision sonar data. The sonar operations were conducted in three missions, one on each day, with the boat and jet skis operating concurrently. The USGS airborne EAARL-B mapping system flown in a twin engine plane was used to collect lidar data. The lidar operations were conducted in three missions, one in the afternoon of August 19, 2015, and two more in the morning and afternoon of August 20, 2014. The missions were synchronized such that there was some temporal and spatial overlap between the sonar and lidar operations. Additional data were collected to evaluate the actual water clarity corresponding to lidar's ability to receive bathymetric returns. This dataset serves as an archive of processed single-beam and lidar bathymetry data collected at Cape Canaveral, Florida, in 2014 (in XYZ comma-delimited, ASCII and shapefile format). Also included in this archive are Geographic Information System (GIS) data products: gridded map data (in ESRI© binary and ASCII grid format) and a color-coded bathymetry map (in PDF).卡纳维拉尔角海岸系统（Cape Canaveral Coastal System, CCCS）是美国东南海岸线的标志性地貌，同时也是北卡罗来纳州费尔角以南唯一的大型海岬。该系统的大部分区域隶属于梅里特岛国家野生动物保护区，其管辖范围还涵盖卡纳维拉尔角空军基地（Cape Canaveral Air Force Station, CCAFS）、美国国家航空航天局（National Aeronautics and Space Administration, NASA）肯尼迪航天中心（Kennedy Space Center, KSC）以及卡纳维拉尔角国家海岸的大片区域。现代海岬的实际岬角主体位于CCAFS的管辖边界内。各相关机构持续关注该系统的侵蚀灾害与脆弱性问题，涉及关键基础设施、栖息生境、休闲与文化资源。 美国地质调查局（United States Geological Survey, USGS）于2014年8月18日至20日在佛罗里达州卡纳维拉尔角附近大西洋海域开展了水深测绘调查（USGS野外活动编号：2014-324-FA）。本次研究的覆盖范围北起佛罗里达州卡纳维拉尔港，南至KSC辖区北端，从岸线向海延伸至约2.5公里海域。水深数据通过单波束声呐与激光雷达（lidar）系统采集。两台水上摩托与一艘搭载USGS SANDS水文系统的17英尺舷外机快艇负责采集高精度声呐数据，本次声呐作业分三个航次开展，每日一个航次，快艇与水上摩托同步作业。搭载于双引擎飞机的USGS机载EAARL-B测绘系统用于采集激光雷达数据，激光雷达作业同样分三个航次：2015年8月19日下午一次，2014年8月20日上午与下午各一次。各航次进行了时间与空间同步，确保声呐与激光雷达作业存在部分重叠时段。此外还额外采集了相关数据，用于评估与激光雷达接收水深回波能力对应的实际水体透明度。 本数据集为2014年在佛罗里达州卡纳维拉尔角采集的经处理单波束声呐与激光雷达水深数据档案，数据格式为逗号分隔的XYZ格式ASCII文件与形状文件（shapefile）。本档案还包含地理信息系统（Geographic Information System, GIS）数据产品：网格化地图数据（ESRI©二进制与ASCII网格格式）以及一张彩色编码水深地图（PDF格式）。
