Globally, natural disasters have been a cause of major distractions in both human activities and lives. Statistically, it accounts for 0.1% of the total deaths in the world (Richie, 2022). They consist of phenomena such as hurricanes, floods, drought, earthquakes and landslides with each region of the earth experiencing one or more. The Caribbean countries, located in the, are extremely vulnerable to climate change and natural disasters (World Bank, 2023). Weather conditions in the region are often extreme which result in a lot of destruction.
Recent developments in the field of Geoinformatics have led to a renewed interest in mapping these disaster scenarios. Geospatial data has become more readily available due to the rise of free and open-source policies. In the context of this hackathon, we demonstrate the power of geospatial technologies in emergency response pre-, during and post- disaster in the Bahamas after Hurricane Dorian.
What it does⚙️
Pre–tracking The pre-tracking site is an ArcGIS story map that we made public and embedded the link into our web application. Here (https://arcg.is/XPyrm), we can see the movement of the hurricane before hitting landfall in the Grand Bahama Island.
During–routing The routing site is designed to provide the emergency responders with the most optimal route to reach victims during the hurricane. The screenshot below shows a sample illustration as to how responders from Calvary Temple in the Pineridge area can use our web app to request routing services to a distress call at the Eight Mile Rock residential area
Post –graph prediction The correlation site shows the simulation graph for the sea level change from 2019 to 2030. This is to act as a post-disaster simulation that would aid emergency responders
How we built it🛠️
Integration of 3 phases on a web application
Challenges we ran into
Currently the web application runs on our local host thus cannot be accessed by the public.
We used proprietary software (ArcGIS Online) to illustrate Phase 1 because due to time constraints that was the quickest way. However, the story map is public and is easily accessible from our web app as an embedded link.
Phase 3 is the less interactive section in our application since the majority of our data is static.
Accomplishments that we're proud of👏
Our web application integrated all the 3 phases
