Marine Corps Base Camp Lejeune Onslow Beach Laser Scanning Data

Critical military training and testing on lands along the nation’s coastal and estuarine shorelines are increasingly placed at risk because of development pressures in surrounding areas, impairments due to other anthropogenic disturbances, and increasing requirements for compliance with environmental regulations. The U.S. Department of Defense (DoD) intends to enhance and sustain its training and testing assets and to optimize its stewardship of natural resources through the development and application of an ecosystem-based management approach on DoD installations. To accomplish this goal, particularly for installations in estuarine/coastal environments, the Strategic Environmental Research and Development Program (SERDP) launched the Defense Coastal/Estuarine Research Program (DCERP) as a minimum 10-year effort at Marine Corps Base Camp Lejeune (MCBCL) in North Carolina. The results of the first six years of the program (DCERP1) are presented here. The overarching objectives of DCERP are to: (1) understand the effects of military training activities, infrastructure development, and other coastal military installations; (2) develop models, tools, and indicators to evaluate ecosystem health; and (3) recommend adaptive management strategies to sustain ecosystem natural resources within the context of an active military installation. This grid file was created from data collected using a Riegl 3-D laser scanner. Millions of x, y, and z points from Onslow Beach were processed using the Terrasolid software package to define a bare-earth model. The beach was broken into a series of zones, each zone was processed separately, and this grid covers all of the zones. Data were collected during the same week and around the low tide (two hours before and after low tide).美国沿海与河口海岸沿线区域的关键军事训练与测试任务，正因周边区域开发压力、其他人为活动造成的生态损害，以及日益严格的环保合规要求，面临愈发严峻的风险。 美国国防部（U.S. Department of Defense, DoD）计划通过在其军事设施中开发并应用基于生态系统的管理模式，强化并维持其训练与测试资产，同时优化自然资源管护工作。为达成这一目标，尤其是针对河口/沿海环境中的军事设施，战略环境研究与发展计划（Strategic Environmental Research and Development Program, SERDP）在北卡罗来纳州的勒琼海军陆战队基地（Marine Corps Base Camp Lejeune, MCBCL）启动了国防沿海/河口研究计划（Defense Coastal/Estuarine Research Program, DCERP），该项目周期至少为10年。 本文展示了该项目前六年（即DCERP1阶段）的研究成果。DCERP的总体目标包括：（1）明晰军事训练活动、基础设施建设及其他沿海军事设施所产生的生态影响；（2）开发用于评估生态系统健康状况的模型、工具与指标体系；（3）提出适配性管理策略，以在现役军事设施的运营背景下维持生态系统自然资源的可持续性。 本网格文件基于Riegl三维激光扫描仪采集的数据生成。昂斯洛海滩（Onslow Beach）的数百万个x、y、z三维坐标点经Terrasolid软件包处理后，构建了裸地模型。该海滩被划分为多个分区，每个分区均单独处理，本网格文件覆盖所有分区范围。数据采集于同一周内，且均在低潮时段（低潮前后两小时）开展。
