Disaster Alert for BD
Read full descriptionHide full description
Disaster Alert for BD automates components of the disaster management process, starting from providing weather updates, subsequent risk prevention and precautionary measures, early warning to risk prone communities, individuals, dissemination and coordination with communities, volunteers, relevant government and non-government organizations, shelter landmarks, fire services, medical service, emergency camps, emergency SMS to relatives, etc. The idea for the application is to create a mechanism where the organizations can be coordinated in real time to ensure that risk reduction efforts are coherent and response efforts ensure no one is overlooked or left behind. During emergency response it is often the nearby communities that receive maximum help whereas the distant ones are relatively deprived. In the event of any emergency, the application would be used to coordinate between key agencies, volunteers in the field and impacted communities. The system would coordinate to ensure that volunteers receive notifications and be directed to provide their assistance at the right locations. As well as ensuring that community members are able to locate the nearest service point for their specific problem or request support from volunteers to their location. This mechanism will also support in mitigating overlaps and gaps in efforts.

Is my street flooded? Tchoup answers that question for New Orleans — live, block by block. WHAT YOU SEE • Flood reports from neighbors: where water is standing right now, how deep (ankle, tire, bumper, up to the windows), confirmed by other people on the block. • Pump station status across the city, updated continuously. • Live rain radar. • River and canal gauges with flood stages. • Underpass danger zones — the low spots where cars drown. They glow red when flood-risk weather is active or flooding is reported nearby. • A shareable "roads to avoid right now" list for the family group chat. WHAT YOU CAN DO • Report flooding in two taps to warn your block. • Confirm or clear other reports so the map stays honest. • Save your home (privately) and get a push notification when a neighbor reports flooding within 1/3 mile. HOW IT STAYS TRUSTWORTHY • Sign-in is one tap (Apple) or a passwordless email link. • You can't confirm your own report. Reports expire after 3 hours unless someone confirms them, and disappear when neighbors say the water's gone. • No ads, no tracking, no data sales. Your home location is never shown to anyone. Turn around, don't drown. If there's water across the road, don't drive into it — check the map, find another way. Tchoup is a product of Edge Orbital, made in New Orleans.
