The collection holds about 7300 maps depicting natural phenomena in rural areas of the Netherlands. The maps contain data on soil science, geomorphology, groundwater, landscape, vegetation, flora and fauna, archaeology and cultural history. The maps were produced from 1945 to 1997.
The Alterra Map Collection combines two map collections created by Alterra’s predecessors. The largest part of the collection comprises approximately 5500 soil maps and maps on related subjects.

The maps were created by the Staring Centrum for Integrated Land, Soil and Water Research (SC-DLO) and its predecessor, the Foundation for Soil Mapping (StiBoKa). Many of the soil maps were published in reports. In that case links to the bibliographic description of the reports in the library catalogue have been added. Most of the maps are digitally available, either with the report or within this collection.
The remainder of the collection contains about 1800 vegetation and fauna maps generated by the former state institutes for forestry and nature research: IBN, ‘De Dorschkamp’ and RIVON. These maps do not contain links to the research reports they were made for. None of these maps are digitized. The maps in this collection are accredited with the names of the researchers who created them. You can find them all by entering 'IBN' in the search box.
The collection was formerly presented as the Alterra Map Database. This database is now closed. The hard copy maps are part of the Library’s Special Collections. Another part of the soil map collection is available at the Gelders Archief. The collection was made around the year 2000 by the research institute Alterra, now Wageningen Environmental Research.
