USGS CoastCam CACO-02 at Marconi Beach, Cape Cod National Seashore, Massachusetts (2021, 2023, 2024): Imagery and Calibration Data

Two digital video cameras (CACO-02) were installed at Marconi Beach, Cape Cod National Seashore in Massachusetts (MA) as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The cameras faced north-east (c1) and east (c2) along the beach and every half hour during daylight hours. They ran daily from March through June 2021, Feburary through July 2023, and January through September 2024; the cameras collected raw video and produced snapshots and time-averaged image products. This data release includes the necessary intrinsic orientation (IO) and extrinsic orientation (EO) calibration data to utilize imagery to make quantitative measurements. USGS researchers analyzed the imagery collected from this camera to remotely sense a range of information including shoreline position, sandbar migration, wave run-up on the beach, alongshore currents, and nearshore bathymetry. These cameras are part of the USGS CoastCam network, supported by the Total Water Level/Coastal Change Project under the Coastal and Marine Hazards and Resources Program (CMHRP).

两台数字摄像机（CACO-02）部署于美国马萨诸塞州（Massachusetts, MA）科德角国家海岸的马科尼海滩（Marconi Beach），作为美国地质调查局（U.S. Geological Survey, USGS）海滩及近岸环境研究项目的组成部分。两台摄像机沿海滩分别朝向东北（c1）与正东（c2）方向，并于日间每半小时采集一次影像。项目运行时段为2021年3月至6月、2023年2月至7月及2024年1月至9月，每日持续采集。摄像机采集原始视频素材，并生成快照及时间平均图像产品。本次发布的数据包含开展定量影像测量所需的内定向（intrinsic orientation, IO）与外定向（extrinsic orientation, EO）校准数据。美国地质调查局科研人员对该摄像机采集的影像进行分析，以遥感获取岸线位置、沙坝迁移、岸滩波浪爬高、沿岸流及近岸水深地形等多类信息。该摄像机隶属于美国地质调查局海岸摄像机网络（USGS CoastCam），该网络由海岸与海洋灾害与资源计划（Coastal and Marine Hazards and Resources Program, CMHRP）下属的总水位/海岸变化项目（Total Water Level/Coastal Change Project）资助。如需了解该摄像机站点的更多详情，请访问：https://www.usgs.gov/centers/whcmsc/science/using-video-imagery-study-marconi-beach
