We mapped soil erosion in the field in 1991-1997 in the scale 1:100 000 for all of Iceland. The results were published in the book "Soil Erosion in Iceland" ("Jarðvegsrof á Íslandi"). The project involved classification of soil erosion forms and desert forms, as well as developing scale for erosion severity. The results consist of a comprehensive databank for soil erosion in Iceland and the geomorphology of Icelandic desert surfaces. The project received the Nordic Nature and Environment prize in 1998. The data has been used for multiple purposes since then and continues to be the most comprehensive land cover for Icelandic desert surfaces.
