Land Cover Map 2022 (25m rasterised land parcels, N. Ireland)

This is a 25m pixel data set representing the land surface of Northern Ireland, 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 LCM2022 products are available from the LCM2022 product documentation.

本数据集为25米分辨率像素级数据集，覆盖北爱尔兰陆地表面，基于《生物多样性行动计划（Biodiversity Action Plan）》的宽泛生境分类体系，被划分为21个UKCEH（英国生态与水文中心，UK Centre for Ecology & Hydrology）土地覆盖类别。该数据集采用GeoTiff格式的三波段栅格结构，由已分类土地地块数据集的三项属性经栅格化处理生成：第一波段代表最可能的土地覆盖类型；第二波段为各地块的土地覆盖概率；第三波段用于衡量地块的分类纯度。其中概率波段与纯度波段均缩放至0至100区间，二者结合可反映分类结果的不确定性。本数据集及所有UKCEH LCM2022产品的完整说明，均可通过LCM2022产品文档获取。
