Modelling Flood Risk
Ramani Huria’s guiding goal has been to improve the flood resilience of the regions mapped. To work towards accomplishing this, community mappers identify areas on a basemap that are most detrimentally affected by floods. Thereafter, they use pencil to map flood prone areas upon tracing paper over a basemap. The output of this is then scanned and the contained data is digitized into shapefiles and uploaded onto OpenStreetMap.
When the maps are finished, they are combined with other data in InaSAFE to run realistic flooding scenarios. The findings are collected and lead to the development of tailored training in disaster preparation for ward officials and community members.
InaSAFE is free software that produces realistic natural hazard impact scenarios for better planning, preparedness, and response activities. It provides a simple but rigorous way to combine data from scientists, local governments and communities to provide insights into the likely impacts of future disaster events.
InaSAFE is a Free and Open Source Software (FOSS) project, published under the GPL V3 license. You may freely download, share and (if you like) modify the software.
