The global map of tree species richness

Estimated tree species richness per hectare. This map can be downloaded in two formats. One is a geoTIFF file (S_mean_raster.tif) containing the fully geo-referenced map of tree species richness worldwide at a 0.025°×0.025° resolution. The other is a comma-separated file (S_mean_grid.csv) with the following attributes: S is local average tree species richness per hectare x, y are centroid coordinates of all 0.025°×0.025° pixels;每公顷树木物种丰富度估算值。该地图支持两种格式下载：其一为地理TIFF（geoTIFF）格式文件（S_mean_raster.tif），包含全球范围内分辨率为0.025°×0.025°的树木物种丰富度全地理参考地图；其二为逗号分隔值文件（S_mean_grid.csv），其包含以下属性：S为每公顷本地树木物种平均丰富度，x、y为所有0.025°×0.025°像素的质心坐标。
