Imagine trying to keep people safe from a hurricane headed for the coast if you don’t know where people live along that coast. Without settlement locations, place names, and extents, your interventions may be ineffective. This is true not only of emergencies like natural disasters, but of all government and humanitarian planning.
“[Settlement extents can be used] for vaccination campaigns. It helps us identify vulnerable populations that may not have easy access to a health facility. But settlement extents are also being used in a lot of different projects [within GRID3]. It’s helping in planning for bednet distribution, census cartography, and school placement optimisations.”
