Lidar Bathymetry Data of Cape Canaveral, Florida, (2014) in XYZ ASCII text file 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 format).

卡纳维拉尔海岸系统（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。该系统的绝大部分区域位于梅里特岛国家野生动物保护区境内，其管辖范围涵盖卡纳维拉尔空军站（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）以及卡纳维拉尔国家海岸公园的大片区域。现代海岬的实际岬角地带隶属于卡纳维拉尔空军站的管辖边界。上述各管理机构持续关注该系统面临的侵蚀灾害与脆弱性问题，涉及关键基础设施、生态栖息地、休闲与文化资源等多个方面。
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近岸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，南至肯尼迪航天中心园区北端，西起岸线，东至离岸约2.5公里的海域。研究采用单波束声呐与激光雷达（Light Detection and Ranging, LiDAR）系统采集水深数据：两艘水上摩托与一艘搭载USGS SANDS水文系统的17英尺舷外机船艇负责采集高精度声呐数据，声呐作业分为3个航次，每日开展1次，船艇与水上摩托同步作业；激光雷达数据则通过搭载于双引擎飞机的USGS EAARL-B机载测绘系统采集，激光雷达作业分为3个航次，1次于2015年8月19日下午开展，另外2次分别于2014年8月20日上午与下午开展。各航次进行了协同安排，确保声呐与激光雷达作业在时间与空间上存在部分重叠。此外，研究团队还采集了额外数据，用于评估与激光雷达接收水深回波能力相关的实际水体透明度。
本数据集为2014年于佛罗里达州卡纳维拉尔采集的经处理单波束与激光雷达水深数据的存档文件，数据格式包括XYZ逗号分隔格式、ASCII格式与形状文件（Shapefile）格式。本存档文件还包含地理信息系统（Geographic Information System, GIS）数据产品：栅格地图数据（ESRI二进制与ASCII栅格格式）以及彩色编码水深地图（PDF格式）。
