Abstrakt

The availability of satellite images for academic or commer- cial purpose is increasing rapidly due to efforts made by governmental agencies (NASA, ESA) to publish such data openly or commercial startups (PlanetLabs) to provide real- time satellite data. Beyond many commercial application, satellite data is helpful to create situation awareness in dis- aster recovery and emergency situations such as wildfires, earthquakes, or flooding. To fully utilize such data sources, we present a scalable system for the contextual enrichment of satellite images by crawling and analyzing multimedia content from social media. This information stream can provide vital information from the ground and help to com- plement remote sensing in situations. We use Twitter as main data source and analyze its textual, visual, temporal, geographical and social dimensions. Visualizations show dif- ferent aspects of the event allowing high-level comprehension and provide deeper insights into the event as complemented by social media.
