Abstract: This special issue of Geomorphology consists mainly of selected papers from the S15 Session: GIS and SDA applications in Geomorphology at the 6th International Conference on Geomorphology held in Zaragoza (Spain) in September 2005. For this session, 53 abstracts from Europe, Asia, the Americas, Africa and Oceania were submitted, and 18 oral communications and 35 posters were presented. The session provided an opportunity to overview, discuss and evaluate new advances of GIS (Geographical Information Systems) and SDA (Spatial Data Analysis) applications in the field of geomorphology. Eight of the manuscripts submitted for the publication call for this special issue survived the review process, and two other invited contributions together form this special issue with 10 papers.
