The 2019 IEEE GRSS Data Fusion Contest, organized by the IADF TC in collaboration with the Johns Hopkins University (JHU) and the Intelligence Advanced Research Projects Activity (IARPA), was opened on January 11, 2019. The final phase was opened on March 7 and closed on March 22. We received over 1100 submissions!

We would like to thank all the participants for their submissions. Evaluation and ranking were conducted by the Organizers, who carefully checked all valid submissions. The winners are reported below along with their approaches and metrics over all the undisclosed ground truth samples.
