Multi-source national forest inventory (MS-NFI) raster maps of 2021
收藏资源简介:
Estimates of variables in map form from multi-source national forest inventory (MS-NFI) for year 2021 by Natural Resources Institute Finland (Luke). The estimates are calculated using field data from the Finnish national forest inventory, satellite images and other digital georeferenced data, such as topographic database of the National Land Survey of Finland. Ten sets of estimates have been produced for the most part of the country and nine sets for Lapland. The number of the map form themes is 45. In addition to the volumes by tree species and timber assortments, the biomass by tree species groups and tree compartments have been estimated. A new set of the products will be produced annually or biannually in the future. The maps are in a raster format with a pixel size of 16m x 16m and in the ETRS-TM35FIN coordinate system. The products cover the combined land categories forest land, poorly productive forest land and unproductive land. The other land categories as well as water bodies have been delineated out using the elements of the topographic database of the Land Survey of Finland.

芬兰自然资源研究所(Natural Resources Institute Finland, Luke)发布了2021年多源国家森林清查(Multi-source National Forest Inventory, MS-NFI)地图格式变量估算数据集。该数据集的估算结果基于芬兰国家森林清查的野外调查数据、卫星影像以及其他数字化地理参考数据(如芬兰国家土地测量局地形数据库)生成。芬兰绝大多数区域生成了10套估算结果,拉普兰地区则生成9套。本次数据集共包含45项地图主题,除按树种与材种划分的材积外,还针对不同树种组及树木组分估算了生物量。未来该系列产品将以每年或每两年的频率更新。 该数据集采用栅格格式(raster format)存储,像素尺寸为16m×16m,坐标系为ETRS-TM35FIN。产品覆盖有林地、低产林地与非生产性林地三类土地类型,其余土地类型及水体已通过芬兰土地测量局的地形数据库要素完成掩膜剔除。 具体主题如下: * 2021年云杉活枝生物量(10 kg/ha) * 2021年云杉干材剩余物生物量(10 kg/ha) * 2021年云杉直径>1cm根系生物量(10 kg/ha) * 2021年云杉伐桩生物量(10 kg/ha) * 2021年云杉枯枝生物量(10 kg/ha) * 2021年云杉干材与树皮生物量(10 kg/ha) * 2021年云杉针叶生物量(10 kg/ha) * 2021年阔叶树活枝生物量(10 kg/ha) * 2021年阔叶树干材剩余物生物量(10 kg/ha) * 2021年阔叶树直径>1cm根系生物量(10 kg/ha) * 2021年阔叶树伐桩生物量(10 kg/ha) * 2021年阔叶树枯枝生物量(10 kg/ha) * 2021年阔叶树干材与树皮生物量(10 kg/ha) * 2021年阔叶树叶片生物量(10 kg/ha) * 2021年松树活枝生物量(10 kg/ha) * 2021年松树干材剩余物生物量(10 kg/ha) * 2021年松树直径>1cm根系生物量(10 kg/ha) * 2021年松树伐桩生物量(10 kg/ha) * 2021年松树枯枝生物量(10 kg/ha) * 2021年松树干材与树皮生物量(10 kg/ha) * 2021年松树针叶生物量(10 kg/ha) * 2021年立地主类(1-4) * 2021年立地肥力等级(1-10) * 2021年土地类型(1-3) * 2021年基于FAO FRA 2021的土地类型(1-4) * 2021年林分年龄(年) * 2021年林分平均直径(cm) * 2021年林分平均树高(dm) * 2021年郁闭度(%) * 2021年阔叶树郁闭度(%) * 2021年林分断面积(m²/ha) * 2021年多源国家森林清查数据来源索引(MSNFI 2021) * 2021年桦木材积(m³/ha) * 2021年桦木纸浆材材积(m³/ha) * 2021年桦木锯材材积(m³/ha) * 2021年云杉材积(m³/ha) * 2021年云杉纸浆材材积(m³/ha) * 2021年云杉锯材材积(m³/ha) * 2021年其他阔叶树材积(m³/ha) * 2021年其他阔叶树纸浆材材积(m³/ha) * 2021年其他阔叶树锯材材积(m³/ha) * 2021年松树材积(m³/ha) * 2021年松树纸浆材材积(m³/ha) * 2021年松树锯材材积(m³/ha) * 2021年活立木总蓄积量(m³/ha) 除以下情况外,像素值即为对应主题变量的数值: * 32766为缺失值:表示该像素属于林业用地但无卫星影像覆盖 * 32767为空值:表示该像素不属于林业用地或位于国境之外 更多信息:[https://www.luke.fi/fi/seurannat/valtakunnan-metsien-inventointi-vmi]
