The Brazilian Symposium on Geoinformatics (GEOINFO) is an annual conference for exploring research, development, and innovative applications in geographic information science and related areas. Papers should describe original ongoing or recently finished work. An international scientific committee will review the submissions.

The GEOINFO 2020 Demonstration session complements the overall program of the Symposium. It is designed to provide an exciting and highly interactive way to demonstrate tools for storing, processing, analyzing and visualizing spatial and spatio-temporal data. This is an excellent opportunity to advertise the applicability of the developed tool and to obtain feedback from the community in geoinformatics. Tool Demonstration papers should be related to the topics of interest of the main conference track. The session is focused on academic and research software, and it is not intended for the demonstration of commercial products.

The GEOINFO conferences also aim to bring to Brazil leading GIScience and spatial database researchers, to present to the local community a perspective of the state-of-the-art in the area. Past speakers have included Max Egenhofer, Gary Hunter, Andrew Frank, Roger Bivand, Mike Worboys, Werner Kuhn, Stefano Spaccapietra, Ralf Guting, Shashi Shekhar, Christopher Jones, Martin Kulldorff, Andrea Rodriguez, Max Craglia, Stephen Winter, Edzer Pebesma, Fosca Giannotti, Christian Freksa, Thomas Bittner, Markus Schneider, Helen Couclelis, Randolph W. Franklin, Paul Brown, Michael Batty, Ahmed Eldawy, Clodoveu A. Davis Jr., Duncan Smith, André Lage Freitas, Laércio Massaru Namikawa, Joana Barros and Claudia Bauzer Medeiros.
