Pan-European Maps of Canopy Fuels

WORKING VERSION. All layers will be visible in this linked webgis app along with estimated error. <== To Be Updated in new final version, not yet so. The layers available in this dataset are in a WGS84 geographic coordinate reference system (EPSG:4326) where latitude and longitude coordinates at 0.0008983 degrees ground sampling distance per cell, which corresponds to about 1 ha, i.e. ~100 m x ~100 m at the equator, but decreases in area with increasing latitude as the coordinate system is not equal-area, e.g. ~70 m west-est direction at 45° latitude and ~50 m west-est direction at 60° latitude. A_Aspect.tif, A_slope.tif and A__elevation.tif - Earth surface height above sea level and morphology. Prefix was added to group them in Zenodo. biomass.tif - Biomass values at year 2020, Mg/ha. canopyBulkDensity.tif - Amount of canopy biomass per volume of canopy (kg/m3) canopyBaseHeight.tif - Height of canopy start measured from the ground (m) canopyCover.tif - percent of canopy coverage - resampled and updated from the map of Hansen et al. 2005 canopyHeight.tif - Total height of canopy from the ground (m) - resampled from the map of Lang, N., et al. (2023) Fuel Model FuelModelClasses_ScottBurgan.tif - the category of Fuel Model according to Scott&Burgan 2005 FuelModelClasses_Aragonese.tif - the category of Fuel Model according to Aragonese et al. 2023 DOI: 10.5194/essd-15-1287-2023 - values are from 1 to 24, with a Look Up Table for correspondence (values are ordered matching the order in table 1 of the article) . FuelModelClasses_ScottBurgan.clr/qml CLR/QML - style file for QGIS FuelModelClasses_Aragonese.clr/qml CLR/QML - style file for QGIS FuelModelPercent.tif - the percent of fuel model category belonging to that pixel, values range between 50 and 100. Allows to spot pixels with expected mixed fuel categories.试用版本：本数据集的所有图层将在关联的WebGIS应用中展示，并附带估算误差。<== 本内容将在最终正式版本中更新，当前尚未完成更新。 本数据集所用图层均采用WGS84地理坐标系（WGS84 geographic coordinate reference system，EPSG:4326），单个栅格单元的地面采样距离为0.0008983度，对应面积约1公顷，即赤道处约100米×100米；由于该坐标系并非等面积投影，随纬度升高，单个栅格的实际面积会逐渐缩小：例如在45°纬度处，东西方向边长约70米，60°纬度处约50米。 A_Aspect.tif、A_slope.tif及A__elevation.tif：用于表征地表海拔高度与地表形态特征。为便于在Zenodo平台中对其进行分组管理，新增了统一前缀。 biomass.tif：2020年生物量数值，单位为兆克每公顷（Mg/ha）。 canopyBulkDensity.tif：单位冠层体积内的冠层生物量，单位为千克每立方米（kg/m³）。 canopyBaseHeight.tif：冠层底部距地面的高度，单位为米（m）。 canopyCover.tif：冠层覆盖百分比，基于Hansen等（2005）的研究成果重采样并更新得到。 canopyHeight.tif：冠层总高度（距地面），单位为米（m），基于Lang N.等（2023）的研究成果重采样得到。 FuelModelClasses_ScottBurgan.tif：基于Scott与Burgan（2005）研究定义的燃料模型分类栅格。 FuelModelClasses_Aragonese.tif：基于Aragonese等（2023）研究（DOI: 10.5194/essd-15-1287-2023）定义的燃料模型分类栅格，取值范围为1至24，类别对应关系可通过查找表获取（数值顺序与该文献表1中的排列顺序一致）。 FuelModelClasses_ScottBurgan.clr/qml：QGIS专用样式文件（CLR/QML格式）。 FuelModelClasses_Aragonese.clr/qml：QGIS专用样式文件（CLR/QML格式）。 FuelModelPercent.tif：单个栅格像素所属燃料模型类别的占比，取值范围为50至100，可用于识别存在混合燃料类别的像素。
