The International Geoscience and Remote Sensing Symposium (IGARSS) will be held online from 11 to 16 July 2021.

IGARSS is the foremost annual international symposium for the combination of remote sensing (earth observation) and geosciences. Previous editions of the symposium were held in America, China, Japan and Australia. In 2021, Belgium and the Netherlands will co-host the aptly themed "Crossing Borders" symposium.


Among the topics to be discussed at IGARSS 2021 are socially relevant challenges such as climate change, the energy transition, the food problem, migration and pandemics. There will also be a focus on smart and green cities and on the collaboration between earth observation satellites, drones and navigation systems such as GPS and Galileo.
