The GLOFAS presentation at the start of FloodHack described the RedCross using GLOFAS to help with the forecasting of potential local flooding and the possibility to pre-empt a catastrophe. GLOFAS is a global product and presents coarse data. We thought that this was too coarse for local users, especially non-technical users to interpret. More importantly, it might be hard to visualise the consequences if nothing is done.
Using the GLOFAS data and other geospatial information, we wanted to improve the visualisation experience by trying to use the data, not just visualising it.
What it does
Based on a down-sampled AsterDEM, creates a simple flood simulation that is local.
By accessing GLOFAS forecast data through Rasdaman, provide visual information about the emergency level of the flood forecast through an infographic.
How we built it
Challenges we ran into
Extract data from GLOFAS via Rasdaman. Mixing coarse and fine data for visualisation
Accomplishments that we're proud of
Dynamic browser visualisation and client side data processing.
What we learned
Lot's of JS.
What's next for FloodIT
Integration into the operational GLOFAS
