Land Cover Map 2019 (25m rasterised land parcels, GB)

This is the 25m rasterised land parcels dataset for the UKCEH Land Cover Map of 2019 (LCM2019) representing Great Britain. It describes Great Britain's land cover in 2019 using UKCEH Land Cover Classes, which are based on UK Biodiversity Action Plan broad habitats. This dataset was derived by rasterising the corresponding LCM2019 land parcels dataset into 25m pixels. It is provided as a 3-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. LCM2019 represents a suite of geospatial land cover datasets (raster and polygon) describing the UK land surface in 2019. These were produced at the UK Centre for Ecology & Hydrology by classifying satellite images from 2019. LCM2019 was simultaneously released with LCM2017 and LCM2018. 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2019年英国中心生态与水文研究所（UKCEH）土地覆盖图（LCM2019）的25米分辨率栅格化土地地块数据集，代表大不列颠岛。该数据集以UKCEH土地覆盖分类为基础，描述了2019年大不列颠岛的土地覆盖情况，UKCEH土地覆盖分类源自于英国生物多样性行动计划中的广泛生境。数据集通过将LCM2019对应土地地块数据集栅格化至25米像素而生成。数据提供为三波段、8位整数栅格，其中第一波段为UKCEH土地覆盖类别标识符，第二和第三波段为分类置信度指标。欲获取更详细的信息，请参阅产品文档。LCM2019是一系列地理空间土地覆盖数据集（栅格和多边形）的集合，描述了2019年英国陆地表面状况。这些数据由英国生态与水文中心通过分析2019年卫星图像生成。LCM2019与LCM2017和LCM2018同时发布，是UKCEH土地覆盖图系列中的最新版本，该系列始于1990年大不列颠岛土地覆盖图（现通常称为LCM1990），随后是英国全国性土地覆盖图LCM2000、LCM2007和LCM2015。此项工作得到了自然环境研究理事会（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。有关本数据集的详细信息可在https://doi.org/10.5285/f15289da-6424-4a5e-bd92-48c4d9c830cc中找到。
