GISS Specialty Group Activities at AAG2021

As we are nearing the Annual meeting of AAG, we wanted to highlight the sessions that the Geographic Information Systems and Science Specialty Group (GISSG) is sponsoring this year. Despite the virtual format of the conference, the GISSG will host and co-host 45 sessions. Highlights include the following:

Tobler Lecture Series – This is the GISSG’s signature lecture series. This year we will host Dr. Elizabeth Delmelle and Dr. Robert Roth in a back-to-back plenary, who will showcase the significant contributions of geographers to the GIScience discipline.

Best Student Paper Competition – Every year, GISSG hosts best student paper competition. These papers highlight the advancements in the GIScience discipline from a methodological and application perspective. Please join us in getting a glimpse into the future of GIScience discipline through the lens of upcoming researchers.

Geospatial Health Symposium – There are six sessions organized as part of this symposium that focus on spatiotemporal modeling of COVID-19 and other public health issues including substance use that has increased during the pandemic. The sessions also highlight the role of GIScience fundamentals in understanding, modeling and visualizing public health related research.

Symposium of Human Dynamics Research – This symposium will also host six sessions that focus on the role of spatiotemporal analytics, static and dynamic big data and geo-visualization in exploring, modeling and visualizing the interaction between human and natural systems across space and time.

Spaces of Education – The COVID_19 pandemic highlighted the vulnerability of our current educational system. These sessions reflect on the use and impact of geospatial technologies and techniques in education that can be used to build a GIScience education resilient to changing conditions.

Towards Computational Praxis for Social Justice – Like many issues, the COVID_19 pandemic has brought forth to our attention the issue of social justice, which is though not new, has fallen off the radar. These sessions are highlighting the role of computation and GIS in exploring social justice issues while exposing the nuances of using different techniques and technologies to study social justice.
