Andries Heyns, a GIS Flying, explains why it is important to map in the area of MSF activities, such as food distributions. Starting in March 2021, the Missing Maps volunteers mapped over 324,000 buildings in the regions of Anosy and Androy in support of the MSF explo and projects. During the ongoing malnutrition crisis, the OpenStreetMap data has been used for population analysis, planning WatSan activities, and navigation, among other things.
