This book constitutes the refereed proceedings of the 8th International Symposium on Spatial and Temporal Databases, SSTD 2003, held at Santorini Island, Greece in July 2003.The 28 revised full papers presented together with a keynote paper were carefully reviewed and selected from 105 submissions.
