Modelled vascular plant species richness of South Africa and neighbouring territories

A raster in GeoTiff format at 0.0417° resolution (coordinate reference systems EPSG: 4326) of vascular plant species richness in South Africa, Swaziland and Lesotho, predicted from the full boosted regression tree model. The modelled output includes prediction to areas for which species richness was not included in the data used for model construction (Swaziland and Lesotho). Species richness is expressed as counts per quarter degree square.本数据集为分辨率0.0417°的GeoTiff格式栅格数据，采用EPSG:4326坐标系，涵盖南非、斯威士兰及莱索托的维管植物物种丰富度预测结果，基于完整提升回归树模型生成。该建模输出包含了模型构建所用数据集未覆盖的区域（斯威士兰与莱索托）的物种丰富度预测值，物种丰富度以每四分之一度网格内的物种计数进行表征。
