Bathymetric lidar to support pre-engineering analysis for marine liquefied natural gas transport infrastructure

Pieridae Energy提议在新斯科舍省的 位于盖斯伯勒县戈德博罗的东岸。该设施的建设包括一个码头和一个码头 从海岸线向外延伸约1公里，进入20米水深。有关的准确信息 需要海底的地质和深度来规划设施的建设在最合适的地方 位置，以最大限度地减少对环境的影响。新斯科舍社区学院的应用 地球信息学研究小组(AGRG)最近获得了一种地形-水深激光雷达系统，该系统可以 用于在飞机上使用激光测量陆地高度和水深。这 遥感方法避免了船基采样的潜在挑战，包括导航 危害大、成本高、调查时间长。AGRG将使用在激光雷达期间收集的数据 在地理信息系统(GIS)中进行测量，以帮助完善码头和码头的位置和 计算建造LNG终端的这些关键部件所需的填充物体积估计 基础设施。

Pieridae Energy is proposing construction of a marine liquefied natural gas (LNG) terminal on Nova Scotia's eastern shore at Goldboro, in Guysborough County. Construction of the facility involves a wharf and a jetty extending from the shoreline approximately 1 km out into 20 m water depth. Accurate information on the geology and depth of the ocean bottom are required to plan construction of the facility in the most suitable location in order to minimize environmental impact. The Nova Scotia Community College's Applied Geomatics Research Group (AGRG) has recently acquired a topographic-bathymetric lidar system that can be used to obtain measurements of the land elevation and water depth using a laser onboard an airplane. This method of remote sensing avoids potential challenges of boat-based sampling, which include navigational hazards, high costs, and longer length of time to survey. AGRG will use the data collected during the lidar survey in a Geographic Information System (GIS) to help refine the location of the wharf and jetty and calculate volumetric estimates of infill required to construct these critical components of the LNG terminal infrastructure.
