LiDAR-derived digital elevation model of Whale's Tail Marsh, San Francisco Bay, 2019

Data presented are a geospatially-aligned (NAD83) raster image with raster values as bare-earth elevation values (NAVD88) of mudflats, marsh, and levees around Whale's Tail Marsh, South San Francisco Bay (Hayward/Union City). Data presented are a subset of a larger LiDAR survey of the region contracted by the Alameda County Public Works Agency, trimmed to the region of study by Lukas WinklerPrins. 
While these data have been tested for accuracy and are properly functioning, Alameda County and the Alameda County Flood Control and Water Conservation District disclaims any responsibility for the accuracy or correctness of the data. In addition, the use and/or reliance of the information by any other party shall be at their own risk.

本次提供的数据为经地理空间对齐（NAD83）的栅格影像，其栅格值为旧金山湾南部鲸鱼尾沼泽（海沃德/联合城周边）潮滩、沼泽与堤防的裸地高程值（NAVD88）。
本次提供的数据为该区域更大范围激光雷达（LiDAR）勘测数据集的子集，该勘测由阿拉米达县公共工程部承揽，由Lukas WinklerPrins裁剪至研究区域范围。
尽管本数据集已完成精度验证且可正常运行，但阿拉米达县及阿拉米达县防洪与水资源管理区不对本数据的准确性与正确性承担任何责任。此外，任何第三方使用或依赖本信息所产生的风险均由其自行承担。
