Abstract

The U.S. Army Corps of Engineers (USACE), the US Naval Oceanographic Office (NAVO) and the National Oceanic and Atmospheric Administration (NOAA) formed the Joint Airborne Lidar Bathymetry Technical Center of eXpertise (JALBTCX) in 1998 under a collaborative agreement to support coastal mapping and charting requirements at their respective agencies. The two-decade legacy of the JALBTCX includes the development of state-of-the-art remote sensing platforms in coordination with industry and academia. The Coastal Zone Mapping and Imaging Lidar (CZMIL) is the Center's next-generation remote sensing technology initiative. Fielded and operated by the (USACE), it provides advanced coastal mapping capabilities and environmental information products to researchers, engineers and decision makers in government and academia. Previous technology initiatives of the JALBTCX produced the Scanning Hydrographic Operational Airborne Lidar Survey (SHOALS) system and the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system. The third-generation CZMIL system builds upon these initiatives by integrating state-of-the-art laser, receiver, scanner, and imaging hardware with a custom data processing package to facilitate efficient field-to-finish survey operations. This paper compares CZMIL data coverage acquired along the West Ship Island, MS to previous coverage acquired with JALBTCX's SHOALS and CHARTS systems. The comparison demonstrates CZMIL's system performance in shallow, turbid coastal environments where the capabilities of legacy systems were limited by water clarity. CZMIL data supports the development of traditional and innovative information products to address regional environmental challenges. Accessible via web services a consumable and understandable form, the products provide critical, baseline ocean information layers that are required to achieve a conceptual National Ocean Enterprise.
下一代海岸测绘以推进国家海洋事业
美国陆军工程兵团(USACE)、美国海军海洋学办公室(NAVO)和国家海洋和大气管理局(NOAA)于1998年根据合作协议成立了联合机载激光雷达测深技术中心(JALBTCX),以支持各自机构的海岸测绘和制图需求。JALBTCX的20年遗产包括与工业界和学术界协调开发最先进的遥感平台。海岸带测绘和成像激光雷达(CZMIL)是该中心的下一代遥感技术倡议。它由USACE部署和运营,为政府和学术界的研究人员、工程师和决策者提供先进的沿海制图能力和环境信息产品。JALBTCX之前的技术计划包括扫描海道测量操作机载激光雷达测量(SHOALS)系统和紧凑型海道测量机载快速全面测量(CHARTS)系统。第三代CZMIL系统建立在这些举措的基础上,通过集成最先进的激光、接收器、扫描仪和成像硬件以及定制的数据处理包,以促进高效的现场到完成测量操作。本文将沿西船岛、MS获得的CZMIL数据覆盖范围与JALBTCX的SHOALS和CHARTS系统先前获得的覆盖范围进行了比较。对比显示了CZMIL系统在浅水、浑浊海岸环境中的性能,在这些环境中,传统系统的能力受到海水清晰度的限制。CZMIL数据支持传统和创新信息产品的开发,以应对区域环境挑战。这些产品以可消费和可理解的形式通过web服务访问,提供了实现概念性国家海洋企业所需的关键的基线海洋信息层。
