From the 10th until the 18th of September the 86th International Fair (https://thessalonikifair.gr/en) takes place in Thessaloniki. Thessaloniki International Fair is the largest exhibition institution in Greece, and a multifaceted event of entrepreneurial and entertainment value with international radiance. The theme of the fair is “a world in change”. NIVA’s Use Case 1A (Earth Observation Monitoring and Traffic Lights) fits right into this theme. At the desk of our Greek NIVA partner OPEKEPE the visualization of the Use Case is used to inform participants on the work and results of NIVA UC1A.
