This paper provides a description of the Multimedia Satellite Task at MediaEval 2019. The main objective of the task is to extract complementary information associated with events which are present in Satellite Imagery and news articles.
Due to their high socio-economic impact, we focus on flooding events and built upon the last two years of the Multimedia Satellite Task. Our task focuses this year on flood severity estimation and consists of three subtasks: (1) Image-based News Topic Disambiguation, (2) Multimodal Flood Level Estimation from news, (3) Classification of city-centered satellite sequences. The task moves forward the state of the art in flood impact assessment by concentrating on aspects that are important but are not generally studied by multimedia researchers.
