• Timeliness: not yet fully achieved
• Delay: most of the waiting time depends on the availability of the first usable post event
satellite image
• Tasking: Social Media can help to better understand the context
• Map quality: the existing layers quality can be improved thanks to in-situ data
• Optical Satellite Limitations: the acquisitions are influenced by the weather and the
day/night
• SAR Satellite Limitations: mapping floods in the urban and forestry areas is still difficult
due to technical limitations
• New contents: a Social Crisis Map could be provided as a new informative layer

• Multiple sources: Twitter, Flickr, Youtube, GDELT
• Multi-language: about 40 languages supported like English, Spanish, Chinese, Arabic,
German, French, Portoguese, Italian…
• Multiple events: Support for Flood, Windstorm/Hurricane, Earthquake, Fire
• Automatic geolocation extraction: using NLP with quality ranking when native geolocation is
not present
• Automatic filtering: filtering of the posts containing relevant content using Deep Learning
• Crowd validation: enhance post geolocation and validate relevant content
