The University of Salzburg hosts again the international GI community from July 2 – 5, 2013: The interdisciplinary GI_Forum attracts an international GIScience audience with the goal of promoting interest in translating theory, methods and techniques into a broad range of GI application domains. Young researchers are especially invited to contribute and discuss their research. Together with recognized scientists they will find a vibrant community from academia, business, and education ready to embrace new ideas and explore new research directions.
