The European Digital Archive of Soil maps: The Soil Maps of Africa Senthil Selvaradjou and Luca Montanarella EUROPEAN COMMISSION JOINT RESEARCH CENTRE Institute for Environment and Sustainability Slide 2 European Digital Archive of Soil Maps Digitize existing soil maps available in a number of archives (ISRIC, FAO, WOSSAC, IRD,) Make this information available to all users and interested stakeholders Permanently store rare and valuable soil data in a centralized system for future uses Georeference the archived digital soil maps Vectorize the raster files as input in GIS systems Slide 3 The Institute of Environment and Sustainability (IES) of the European Commission (Italy) and ISRIC World Soil Information initiated the European Digital Archive of Soil Maps (EuDASM) in October 2004, by conserving the information on existing soil maps at regional-, national and global scale. EuDASM aims to support the fast- developing, thematic, digital soil mapping strategies pertaining to soil protection. EuDASM - Volume I: SOIL MAPS OF AFRICA contains More than 2000 soil and related maps in digital format from African countries at different scale and coverage levels: continental level (overall coverage - 82, Northern Africa 15; Southern Africa 15; Eastern Africa 30; Western Africa 15; ), Algeria (25), Angola (12), Benin (15), Botswana (47), Burkina Faso(37), Burundi (1), Cameroon (66), Cape Verde (10), Central African Republic (12), Chad (70), Comoros (3), Congo-DR (6), Congo PR (9), Cte dIvoire (39), Egypt (75), Ethiopia (49), Gabon (13), Gambia (20), Ghana (76), Guinea (29), Kenya (343), Lesotho (17), Liberia (4), Libya (19), Madagascar (42), Malawi (10), Mali (33), Morocco (23), Mauritania (12), Mauritius (7), Mozambique (48), Namibia (8), Niger (22), Nigeria (180), Reunion (2), Rwanda (13), Senegal (21), Seychelles (4), Sierra Leone (21), Somalia (18), South Africa (67), Saint Helena (9), Sudan (27), Swaziland (19), Tanzania (98), Togo (40), Tunisia (26), Uganda (11), Zambia (54), Zimbabwe (64) Maps are presented full-scale, with thumbnail pictures and metadata to permit user- friendly navigation The maps in EuDASM - Volume I are holdings of ISRICs World Data Centre for Soils (http://www.isric.org/).
