Very High Resolution Seafloor Classification and Satellite Derived Bathymetry of Lancelin, Australia (IMSA)

Mapping of benthic habitat and seafloor bathymetry of Lancelin, WA derived from satellite imagery captured on 17 July 2017 at a spatial resolution of 2 m. Mapping extent covered as much of the Defence gazetted waters as possible, to a depth of approximately 18 m based on water clarity. Recently dead or senesced (e.g. winter dieback of leaves) and mobile seagrass have the same satellite signature as live seagrass at spectral resolutions of the sensor (WorldView-2). This ensured areas of winter dieback and/or senescence were captured as areas of seagrass for the purposes of impact assessment.

西澳大利亚州兰斯林（Lancelin）区域的底栖生境与海底水深测绘数据集，基于2017年7月17日采集的卫星影像生成，空间分辨率为2米。测绘范围尽可能覆盖国防部公告划定的全部水域，受限于水体透明度，本次测绘的最大水深约为18米。在该传感器（WorldView-2）的光谱分辨率条件下，近期死亡、衰亡（如海草叶片冬季枯萎）以及移动性海草，与活体海草具有一致的卫星光谱特征。这使得在开展影响评估工作时，冬季枯萎和/或衰亡的区域会被归类为海草分布区。
