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.

Pieridae能源公司提议在新斯科舍省的 位于盖斯伯勒县戈德博罗的东海岸。该设施的建设涉及一个码头和一个突堤 从海岸线向外延伸约1公里，水深20米。的准确情况 需要根据海底的地质和深度来规划设施的建设， 以尽量减少对环境的影响。新斯科舍省社区学院的应用 Geomatics Research Group（AGRG）最近获得了一个地形-测深激光雷达系统， 用于使用飞机上的激光获得陆地海拔和水深的测量值。这 遥感方法避免了基于船的采样的潜在挑战，包括导航 危险、高成本和较长的调查时间。AGRG将使用激光雷达期间收集的数据 在地理信息系统（GIS）中进行测量，以帮助确定码头和突堤的位置， 计算建造LNG接收站这些关键部件所需填充物的体积估算 基础设施演进
