GRID3 Sierra Leone Social Distancing Layers, Version 1.1

GRID3 Sierra Leone Social Distancing Index, Version 1.1 highlights variations in ease of social distancing in urban settings, calculated using population density and building footprints. URBAN POINTS: Urban centre names and locations. URBAN EXTENTS: Polygons of the urban extents. INDEX: A value of 1 is indicative of relative ease of social distancing due to low population density and ample space around buildings. A value of 10 is indicative of high difficulty in maintaining social distancing due to very high population density and very little space around buildings.

GRID3 Sierra Leone Social Distancing Layers (Index), Version 1.1 is an update of the original Version 1.0. The gridded population dataset (WorldPop and Statistics Sierra Leone, 2021), used in calculating the mean population density for the index, has been updated due to errors in the input population dataset of version 1.0. The original GRID3 Sierra Leone Social Distancing Layers (Index), Version 1.0 should no longer be used
