The UNESCO/AETFAT/UNSO (White's) Vegetation Map of Africa was published in 1983 after more than 15 years of collaboration between UNESCO and AETFAT (Association pour l'Etude Taxonomique de la Flore De l'Afrique Tropicale). The original product comprises three map sheets at a scale of 1:5,000,000. These maps were digitized by GRID in their original Miller Oblated Stereographic Projection, and later rasterized at a cell (pixel) size of 30 seconds latitude/longitude resolution (approximately one-kilometer square). The digital product distributed by GRID covers the entire continent of Africa and Madagascar in a single data file.
