Inspiration
Terra Nova is a simple social welfare app that has the potential to save your life someday.
What it does
In the case of a natural calamity like an earthquake, the app detects whether the user is within the affected region and stores the users current location on a server. Information from all such devices in the affected regions is provided to search and rescue team to aid them to find the worst affected regions and take the appropriate actions. The app also allows users to inform the authorities about their well being in case they are safe.
How I built it
We get the information about earthquakes from USGS API and use cellular data or wifi to get users location. Webpage displays the natural calamity and the population.
Accomplishments that I'm proud of
We plot the locations of all users in the vicinity of an earthquake that has a magnitude of 5 or higher on the Richter scale. The map is dynamic and can be updated in real-time. It serves the purpose of giving the authorities a visual summary of the affected population. Another features is to inform the emergency contacts of the victims via SMS.
What's next for Terra Nova
In the future we hope to make the experience of setting up and using the app more user friendly. We plan to support more calamities like tsunamis and warnings about such calamities. If the app gains popularity we could allow special provisions for it to contact the authorities even without network availability (like 911 calls).
