Land Cover Map 2023 (25m rasterised land parcels, GB)

This is a 25m pixel data set representing the land surface of Great Britain, classified into 21 UKCEH land cover classes, based upon Biodiversity Action Plan broad habitats. It is a three-band raster in GeoTiff format, produced by rasterising three properties of the classified land parcels dataset. The first band gives the most likely land cover type; the second band gives the per-parcel probability of the land cover, the third band is a measure of parcel purity. The probability and purity bands (scaled 0 to 100) combine to give an indication of uncertainty. A full description of this and all UKCEH LCM2023 products are available from the LCM2023 product documentation.

本数据集为25米像素分辨率的大不列颠陆地表面数据集，基于生物多样性行动计划（Biodiversity Action Plan）划定的宽泛生境类型，划分为21个英国生态与水文中心（UKCEH）土地覆盖类别。该数据集采用GeoTiff格式，为三波段栅格数据，由分类地块数据集的三项属性经栅格化处理生成。其中第一波段展示最可能的土地覆盖类型；第二波段给出逐地块的土地覆盖概率；第三波段为地块纯度的量化指标。概率波段与纯度波段的取值范围均缩放至0至100，二者结合可反映数据的不确定性程度。本数据集及所有UKCEH LCM2023产品的完整说明，可从LCM2023产品文档中获取。
