    The Symposium on Spatiotemporal Data Science: GeoAI for Social Sciences

    Virginia Tech Research Center – Arlington & George Mason Square

    July 23-24, 2024

    The Symposium on Spatiotemporal Data Science: GeoAI for Social Sciences | China Data Lab (harvard.edu)


    Abstract Submission


    Online Registration


    Co-sponsored by the Vice President’s Office of Virginia Tech, the Vice President’s Office of George Mason University, the NSF-sponsored Spatiotemporal Innovation Center (STC), the Spatial Data Lab project (SDL), the Future Data Lab, and the Journal of Urban Informatics, this symposium aims to promote replicable and expandable spatiotemporal data science with new methodology and innovative technology. The symposium will discuss open data sources, advanced methodology, and cutting-edge technology with a focus on GeoAI for social sciences.

    The symposium will feature plenary speakers, parallel sessions, and posters. The program will include onsite and online sessions. The organization committee plans to select a group of high-quality papers presented at the symposium and recommend them for publishing in a special issue at the Journal of Urban Informatics. Papers submitted for consideration of the special issue still need to go through a regular review process. This symposium will offer an excellent opportunity for participants to network, collaborate, and learn about recent developments in spatiotemporal data science.

    There will be a one-day workshop (July 22, 2024) on spatiotemporal innovation before the symposium.

    • The Spatiotemporal Innovation Institute Program

    Description of the Workshop

    This workshop aims to provide a comprehensive overview of the potential and challenges of some cutting-edge technologies in advancing geospatial science and applications, fostering a deeper understanding and encouraging further exploration and innovation in the field. The workshop will introduce some new tools and applications of GeoAI built on the workflow technology as well as their applications in social science and public health. Participants will learn the GeoAI-based methodology for geospatial analysis, GeoAI tools and packages for spatial data analysis, as well as their applications.

    Topics: 6 hours

    1. Replicable Data Analysis with Geospatial Analytics for KNIME
    2. Develop GeoAI Tools using ChatGPT
    3. Cloud Computing with Google Earth Engine and GeoAI
    4. Geospatial Methods and Tools for the Spatial Assessment of Healthcare Accessibility

    Workshop Registration: https://www.eventbrite.com/e/812024947477 

    Audience: Anyone who is interested in learning the essentials of replicable workflow technology, GeoAI methods and applications in cross-disciplinary domains.

    Abstracts and Instructors:

    I. Replicable Data Analysis with Geospatial Analytics for KNIME

    This workshop will introduce the recent development of workflow technology for replicable spatial data analysis. The topics include: (1) Introduction to KNIME, a free tool for workflow data analysis; (2) Introduction to Geospatial Analytics Extension for KNIME; (3) GeoAI data analysis with KNIME; (4) Case studies of GeoAI and KNIME applications for environmental and socioeconomic studies with big data.

    II. Develop GeoAI Tools using ChatGPT and Python packages

    The first half of this session will introduce GeoLocator - a GeoAI tool re-developed from ChatGPT to detect the location based on the image that was input into the ChatGPT. It will more broadly introduce how to reformulate ChatGPT for geographic studies and research. The second half of this session will introduce a few advanced geospatial and GeoAI methods for spatial prediction, including geographical detectors model, geographically optimal similarity model, the second-dimension spatial association model, and popular R packages which have been downloaded over 120,000 times globally. Case studies of using these methods and tools will be introduced in the session.
