Land Cover Map 2018 (25m rasterised land parcels, GB)

This is the 25m rasterised land parcels dataset for the UKCEH Land Cover Map of 2018(LCM2018) representing Great Britain. It describes Great Britain's land cover in 2018 using UKCEH Land Cover Classes, which are based on UK Biodiversity Action Plan broad habitats. This dataset was derived by rasterising the corresponding LCM2018 land parcels dataset into 25m pixels. It is provided as a three-band, 8-bit integer raster. The first band is the UKCEH Land Cover Class identifier. Bands 2 and 3 are indicators of classification confidence. For a fuller description please refer to the product documentation. LCM2018 represents a suite of geospatial land cover datasets (raster and polygon) describing the UK land surface in 2018. These were produced at the UK Centre for Ecology & Hydrology by classifying satellite images from 2018. LCM2018 was simultaneously released with LCM2017 and LCM2019. These are the latest in a series of UKCEH land cover maps, which began with the 1990 Land Cover Map of Great Britain (now usually referred to as LCM1990) followed by UK-wide land cover maps LCM2000, LCM2007 and LCM2015. This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

本数据集为2018年英国生态与水文中心（UKCEH）土地覆盖图（LCM2018）的25米分辨率栅格化土地地块数据集，描绘了不列颠群岛2018年的土地覆盖情况。该数据集采用UKCEH土地覆盖分类方法，该方法基于英国生物多样性行动计划中的广义生境。数据集通过将相应的LCM2018土地地块数据集栅格化至25米像素尺寸而得。数据集以三通道、8位整数栅格格式提供，其中第一通道为UKCEH土地覆盖分类标识符，第二通道和第三通道为分类置信度指标。欲获取更详尽的描述，请参阅产品文档。LCM2018代表了一套描述2018年英国地表的地理空间土地覆盖数据集（栅格和多边形），由英国生态与水文中心通过分类2018年的卫星图像制作而成。LCM2018与LCM2017和LCM2019同时发布，构成了UKCEH土地覆盖图系列，该系列始于1990年的不列颠群岛土地覆盖图（现通常称为LCM1990），随后是全英国土地覆盖图LCM2000、LCM2007和LCM2015。此项工作得到了自然环境研究委员会（Natural Environment Research Council）资助项目编号NE/R016429/1的支持，作为UK-SCAPE项目的一部分，旨在提供国家能力。关于本数据集的详细信息可在以下链接找到：https://doi.org/10.5285/25c6451b-5c88-40da-9a63-c3ec473e4874。
