The GI_Forum 2015 provides a platform for dialogue among geospatial minds in an ongoing effort to support the creation of an informed GISociety. Bearing in mind different perspectives from a variety of professions, presentations, workshops and exhibitions will concentrate on innovations in education, science and technologies, in the spatial domain and their possible contribution to a more just, ethical and sustainable society. Prominent keynote speakers will highlight new developments, offer insights into trends and visions, and at the same time be available for our Young Researchers' Corner for more individualized interaction with young researchers. GI_Forum runs concurrently with the highly regarded German language conference on Applied Geoinformatics – AGIT. The two symposia share some 1200 participants, the innovative AGIT EXPO exhibit and stimulating social events.Submission deadline for Full Papers and Extended Abstracts is February 1, 2015.
