3rd IJGI Webinar

The Power of Geo-Social Media

Social media as an effective crowdsourcing tool has been widely used for addressing geospatial issues, ranging from urban environments to public health. The social media data tagged with geoinformation play a key role in space related applications, tackling their challenges from a perspective of multiple dimensions. The three talks in this webinar will focus on applications and/or state-of-the-art technologies developed based on geospatial social media, showcasing the its power in geoinformation world.

Date: 4 April 2022


Time: 5:00pm CEST | 11:00am EDT | 11:00pm CST Asia

Webinar Content

On Monday 4 April 2022, MDPI and the International Journal of Geo-Information organized their third webinar entitled “The Power of Geo-Social Media”.

The introduction was held by the Chair of the webinar, Prof. Dr. Wei Huang from College of Surveying and Geo-Informatics at Tongji University in China. His research interests include urban mobility, VGI, spatial analytics and GIScience.

The first speaker to kick off this webinar was Mr. Martin Knura from the g2lab - Lab for Geoinformatics and Geovisualization, HafenCity University Hamburg, Germany. He spoke about using object detection on social media images for urban bicycle infrastructure planning. Martin’s research interests are automated map generalization, geospatial analysis of VGI data, and deep learning applications using geographical vector data.

The second talk with the title "Emojis as a Representation of Spatial Context in Location-based Social Media Posts” was presented by Dr. Eva Hauthal from the Institute of Cartography, Technische Universität Dresden, Germany. Eva Hauthal was a PhD student at the Institute of Cartography at Technische Universität Dresden in the field of emotional cartography and georeferenced user generated content. She continues to work at the Institute of Cartography as a PostDoc researcher and teaches mobile cartography to international students.

Prof. Dr. Ming-Hsiang Tsou from The Center for Human Dynamics in the Mobile Age, Department of Geography, San Diego State University, U.S.A. brought the webinar to an end with his presentation entitled “Applying Geospatial Social Media Analytics in Public Health and COVID-19 Pandemic”. His research interests are in human dynamics, social media, big data, public health, visualization, and Web GIS.

The presentations were followed by a Q&A and a discussion, moderated by the Chair. The webinar was offered via Zoom and required registration to attend. The full recording can be found here on Sciforum website.
