Land Cover Map 2007 (1km raster dominant aggregate class, N. Ireland)

Land Cover Map 2007 (LCM2007) is a parcel-based thematic classification of satellite image data covering the entire United Kingdom. The map updates and upgrades the Land Cover Map of Great Britain (LCMGB) 1990 and LCM2000. Like the earlier 1990 and 2000 products, LCM2007 is derived from a computer classification of satellite scenes obtained mainly from Landsat, IRS and SPOT sensors. It also covers Northern Ireland and incorporates information derived from other ancillary datasets. LCM2007 was classified using a nomenclature corresponding to Joint Nature Conservation Committee (JNCC) Broad Habitats, which encompasses the entire range of UK habitats. In addition, it recorded further detail where possible, incorporating land cover classes sought by other users. LCM2007 is produced in both vector and raster formats, with a number of different versions containing varying levels of detail and at different spatial resolutions. This dataset consists of 1km raster, dominant aggregate class (aggregation of Target Classes). Northern Ireland only.

2007年土地覆盖图（Land Cover Map 2007，LCM2007）是一套基于宗地的专题分类卫星影像数据集，覆盖全英国全域。该数据集更新并升级了1990年大不列颠土地覆盖图（Land Cover Map of Great Britain，LCMGB）与2000年土地覆盖图（LCM2000）。与此前的1990年、2000年版本产品一致，LCM2007主要基于Landsat、IRS及SPOT传感器获取的卫星影像场景，经计算机分类后生成。该数据集同时覆盖北爱尔兰地区，并整合了其他辅助数据集的相关信息。LCM2007采用与联合自然保护委员会（Joint Nature Conservation Committee，JNCC）宽泛生境分类体系相匹配的命名规则，该体系涵盖了英国全境所有生境类型。此外，在可行范围内，该数据集还补充记录了更多细节，纳入了其他用户所需的土地覆盖分类类别。LCM2007提供矢量（vector）与栅格（raster）两种格式，包含多个不同版本，各版本的细节丰富程度与空间分辨率均有所差异。本次提供的数据集为1km分辨率栅格数据，包含优势聚合类别（目标类别的聚合结果），仅覆盖北爱尔兰地区。
