The LASTIG lab is the French leading lab in Geographic Information sciences. The lab covers the complete lifecycle of geospatial data from their capture to their visualisation, including modelling, integration & analysis.
We propose every 2 or 3 months seminars that gather guest keynotes and presentations of lab members/affiliates on a topic at stake. Both mature and on-going works can be featured to stimulate discussions and introduce new lab projects.
Our seminars are hybrid, free, open to everyone, assuming you are preliminarly registered. In case of questions, feel free to reach us at dir-lastig_(at)ign(dot)_fr.
January 16, 2026: Monitoring a dynamic world

Detecting and semantizing changes is of utmost importance for most public policies related to territory planning and monitoring. This explains why four decades of literature in Geographic Information Sciences and Remote Sensing have extensively investigated effective methods in leveraging geospatial data for that multi-faceted purpose.
The LASTIG has been working on this field for a long time among its four research teams. In order to break the existing silos between communities and show the current state of the art, this seminar gathers international experts of the field and current developments in our lab.
