dataGen gives the abundance of 8 common tree genera in the tropical moist forest of the Congo-Basin and 58 geo-referenced variables on 2615 8-by-8 km plots (observations). Each plot's data was obtained by aggregating the data measured on a variable number of previously sampled 0.5 ha sub-plots. Geo-referenced environmental variables were used to describe the physical factors as well as vegetation characteristics. On each plot, 34 physical factors were used pertaining the description of topography, geology, rainfall... Vegetation is characterized through 16-days enhanced vegetation index (EVI) data.
