Large Emergency Event Digital Information Repository
LEEDIR, the Large Emergency Event Digital Information Repository, is a free mobile app and website that lets people share photos and videos with law enforcement and relief agencies during major emergencies, such as natural disasters, terrorist acts, or large-crime events. Agencies can activate LEEDIR in the United States and start receiving citizen submissions immediately after activation.
The platform is designed to crowdsource eyewitness information and helps officials sort, analyze, and manage the media they receive. It runs on a secure cloud infrastructure provided by Amazon Web Services and is offered by CitizenGlobal.
LEEDIR was created by CitizenGlobal in collaboration with the Los Angeles County Sheriff’s Department. It was announced in 2013 and launched for public use in April 2014, after a successful simulation exercise led by the Sheriff’s Department. It has since been used in real events, including civil unrest in Santa Barbara County in 2014 to help gather clues.
The system supports a public safety/private sector collaboration by giving eyewitnesses an easy way to submit media. LEEDIR is available on Android, iOS, and via the web, and submissions can be made anonymously. Video submissions can be long, and there is no limit on the number of photos that can be uploaded.
