High resolution layers 2012 — Dataset

High resolution layers 2012 Year 2012: high-resolution layers — provide information on specific land surface cover characteristics and are suitable for land cover/land use mapping, e.g. in CLC datasets. HRL is created from satellite imagery with a resolution of 20 m using a combination of automatic processing and classification based on interactive rules. To date, five themes have been identified that correspond to the main CLC themes, i.e. compacted soil (tightness), tree density and forest type, (semi-)natural grasslands, wetlands and permanent water bodies.2012年高分辨率图层 2012年推出的高分辨率图层可提供特定地表覆盖特征信息，适用于土地覆盖/土地利用制图工作，例如在CLC数据集中的应用场景。本高分辨率图层（High Resolution Layers，简称HRL）依托分辨率为20米的卫星影像，结合自动处理与基于交互规则的分类方法制作而成。截至目前，已确定五类主题，与CLC的核心主题一一对应，分别为压实土壤（紧实度）、树木密度与森林类型、（半）天然草地、湿地以及永久性水体。
