Greater Haig Fras rMCZ Broad Scale (EUNIS) Habitats

Broadscale habitat (EUNIS level 3) for Greater Haig Fras recommended Marine Conservation Zone (rMCZ).

A broadscale habitat feature class was created to illustrate predicted extent of broadscale habitats present at Greater Haig Fras rMCZ. These broadscale habitats include 'High energy circalittoral rock', 'Moderate energy circalittoral rock', 'Subtidal coarse/mixedsediment', 'Subtidal sand' and 'Subtidal mud' as determined from particle size analysis of sediment samples and descriptive analysis of still images from underwater camera data. The assigned classes at each ground-truth station were used to inform the semi-automated process of map production using object-based image analysis (OBIA).

为推荐设立的大海弗拉斯区域（EUNIS三级）的广泛尺度栖息地，创建了广泛的栖息地特征类别，以展示预测的广泛尺度栖息地范围。这些广泛尺度栖息地包括‘高能环潮间带岩石’、‘中等能量环潮间带岩石’、‘潮下带粗/混合沉积物’、‘潮下带沙’和‘潮下带泥’，这些均由沉积物样品的粒度分析和水下相机数据的静态图像的描述性分析确定。每个地面真实站点分配的类别被用于指导使用基于对象图像分析（OBIA）的半自动化地图制作过程。
