Map A shows OpenStreetMap (OSM) building footprints overplayed onto an aerial. Map B shows predicted building footprint by area. The darker purple areas predict a high frequency of building footprints. The yellow overlay are the OSM building footprint layer. Source: Goldblatt, Jones, & Mannix, 2020, CC BY 4.0
