Geohazard Risk Mapping Initiative is a group of indigenous volunteers who contributes to the mapping buildings and other critical infrastructure of various flood-prone communities in Nigeria. The initiative contributes to open data mapping to enhanced disaster preparedness and effective flood response in Nigeria. In the year 2021, the initiative hosted numerous mapathon events and training on the use of OSM for the new members, GRMI also collaborates with other International Youthmappers to collectively map various communities. Those mapped buildings are further used to build interactive flood early warning maps which are accessible to the public.
Flooding is a natural hazard that inflicted devastating consequences to so many communities in the Nigeria; it occurs every year and causes loss of life and property to the most vulnerable communities. Geohazard Risk Mapping Initiative (GRMI) is an initiative that brings together volunteer to contribute to the mapping of locations that are susceptible to flood during the 2021 rainy season. Those flood prediction maps are made with the goal of sharing with the communities and emergency management agencies so as facilitate flood preparedness. The output of the flood prediction analysis demands information on the location of buildings and road networks, which are to be shown on the map as the potential building and infrastructure that might be affected by the predicted flood.
Hence, GRMI conducted numerous remote mapathon events that entail the mapping of those areas that are susceptible to flooding in Nigeria. Aside from the mapping of buildings by the indigene of Nigeria, GRMI also collaborates with other International Youth mappers to host mapathon event all in the effort of contributing to open data mapping which is critical for effective flood preparedness and response to the most vulnerable communities in Nigeria.
Those contributed open data are then used by the GRMI to develop interactive flood early warning maps (https://bit.ly/3i3o1UP), through this webmap which indicate various flood risk level, the communities member can easily query and search of their house and see the level of risk to flood.
