      • or Option 2: give the presentation and Q&A lively (and use your pre-recording as a backup in case of Internet problems).
  • Symposium program (version: August 3; subject to change): in a PDF
  • Please register for the symposium at:; Early bird fees expired on June 20. 
  • Symposium venue: The Capetonian Hotel (Google Maps)
  • The abstract submission deadline has been extended to May 5, 2023.
  • Special issue on “GeoAI and Location Big Data for Smart Cities” in Computers, Environment and Urban Systems (CEUS); Special issue CFP in PDF. The CEUS special issue is also open to authors who do not plan to participate in the symposium (in that case, please still submit your abstract via the EasyChair link below).

Symposium program & presentation guidelines

The draft program of the symposium is available as a PDF here.

Each presentation (including Q&A) will have 15 minutes. We recommend using max. 12 minutes for presentation, and the rest for Q&A.

More details regarding the participation information will be communicated via emails to the registered participants. 


The increasing use of location-based services, as well as the growing ubiquity of location/activity sensing technologies have led to a huge amount of location-based big data (LocBigData), such as tracking or sensing data (e.g., massive GPS trajectories of people and vehicles, and georeferenced mobile phone data), social media data (e.g., twitter), and crowdsourced geographic information. The growing availability of such data has created unprecedented opportunities for researchers from various disciplines. One of the emerging research fields that are significantly benefiting from LocBigData is GeoAI, which aims to seamlessly integrate geographic knowledge or concepts into AI to address geographical problems or beyond. The unprecedented research opportunities brought by LocBigData and GeoAI also come with new theoretical, technical, ethical, and social questions. This symposium will offer a common ground for researchers from various fields and perspectives to share ideas and research findings, and to discuss the open challenges and future research direction on location-based big data and GeoAI. 

This is a pre-conference symposium associated with ICC 2023, and a follow-up of the successful previous conferences of ICLSM 2015, LSMTD 2017, and LocBigData 2019.

  • Governance of LocBigData and GeoAI


You are invited to submit work-in-progress or position papers with a length of 400-1200 words in PDF format at EasyChair. All submissions should be prepared in English, single column, singled-spaced with figures and tables within the text. A submission should contain author affiliations and email addresses, a short abstract (up to 150 words), and keywords, in addition to the main text. The submission should include succinct and sufficient information about research objectives, significance, method, and preliminary or expected findings.

All submissions will be reviewed. If accepted, at least one of the authors must attend (online or in-person) the symposium to present the work.  Authors of selected submissions will be invited to submit full papers for consideration for publication in the special issue on “GeoAI and Location Big Data for Smart Cities” in Computers, Environment and Urban Systems (CEUS).
