Operational research of airborne topo-bathymetric lidar

海岸带的水深测量在浅水地区往往缺少数据，因为有危险 海洋测量船的导航和传统地形激光雷达测量无法穿透 水柱。沿海地图上缺乏高程信息通常被称为“白丝带缺口” 并对在海岸带内运营的研究人员和商业团体构成独特的挑战。这个 新斯科舍社区学院内的应用地球信息学研究小组(AGRG)最近 获得了AHAB Chiroptera 2地形测深(TOPO-Bathy)激光雷达系统，能够无缝地 测量陆地地形和浅水水深以消除淡水和沿海的这一差距 环境。AGRG将与Leg合作，后者是一家成熟的遥感公司 一家专门从事数字航空摄影和地形激光雷达采集的地图公司，以研究 最有效的方法是使用这种新设备测量海岸带并制作符合以下条件的地图 商业价值。该项目将涉及诺森伯兰海峡的航空测量，那里的贝类 水产养殖是突出的，大西洋海岸和芬迪湾，那里的油轮交通预计将 沿海地区为商业渔业(海胆、海带)提供了各种自然栖息地 海床)，并拥有环境敏感的海岸线，如盐沼。这项新技术还将 支持小型船只港口绘制航道图以确保安全航行，并确定可能需要疏浚的区域，如 以及绘制沉水海藻和生态敏感植物的地图。

Bathymetric surveys in coastal zones are often missing data in shallow water areas due to the danger to navigation for marine survey vessels and the inability of traditional topographic lidar surveys to penetrate the water column. The lack of elevation information on coastal maps is often referred to as the "white ribbon gap" and poses unique challenges to researchers and commercial groups operating within the coastal zone. The Applied Geomatics Research Group (AGRG) within the Nova Scotia Community College has recently acquired an AHAB Chiroptera 2 topographic-bathymetric (topo-bathy) lidar system capable of seamlessly measuring the land topography and shallow water bathymetry to eliminate this gap in freshwater and coastal environments. AGRG will partner with Leading Edge Geomatics (LEG), an established remote sensing mapping firm that specializes in digital aerial photography and topographic lidar acquisition, to research the most efficient method to use this new equipment to survey the coastal zone and produce maps that are of commercial value. The project will involve aerial surveys in the Northumberland Strait where shellfish aquaculture is prominent, the Atlantic Ocean coast and the Bay of Fundy where tanker traffic is expected to increase and the coastal area supports a variety of natural habitats for the commercial fishery (sea urchins, kelp beds), and host environmentally sensitive coastlines such as salt marshes. This new technology will also support small craft harbours to map channels for safe navigation and identify areas that may require dredging as well as mapping the submerged seaweed and ecologically sensitive plants.
