VisualCit – Image-based social sensing toolbox 

Extracting relevant and useful information about situation from Twitter has a great potential to give visual evidence through images and videos.

A short video on VisualCit is available on YouTube (link)

With VisualCit social media analysis tools you can:

  • Crawl twitter with your own keywords to search with posts with images
  • Associate locations to posts, event if tweets are not natively geolocated
  • Apply selected filters (e.g., Not Suitable for Work, Photo/no Photo, Public/Private, People)
  • Use the Project Builder of Citizen Science Center in Zurich to build a crowdsourcing project and let the crowd answer your questions
  • Build thematic maps based on the crowdsourced information
