 "description": "<p>This dataset provides estimated debris generation from building damage. Building damage classifications are derived from Copernicus Emergency Management Service (EMSR927) and SERTIT rapid satellite mapping and harmonized into three categories: <strong>destroyed, damaged, and possibly damaged<\/strong>.<\/p><p>Damage records are matched to building footprints from <strong>Google Open Buildings V3<\/strong> and <strong>OpenStreetMap/Humanitarian OpenStreetMap (HOT/OSM)<\/strong> where Google footprints are unavailable. Building heights from the <strong>Google Open Buildings 2.5D Temporal Dataset V1<\/strong> are used to estimate gross floor area.<\/p><p>Debris generation is estimated by applying category-specific coefficients to the estimated gross floor area. For damaged buildings, a coefficient of <strong>0.5 t/m²<\/strong> is applied, while <strong>0.05 t/m²<\/strong> is applied to possibly damaged buildings. For destroyed buildings, the coefficient varies by settlement type to reflect average differences in construction and material characteristics: <strong>3 t/m² in urban areas, 2 t/m² in peri-urban areas, and 1 t/m² in rural areas<\/strong>.<\/p><p>These coefficients are <strong>average assumptions applied at the settlement-type level and do not represent building-level assessments of construction materials or debris conditions<\/strong>. The resulting values should therefore be interpreted as indicative debris-generation estimates rather than measured quantities.<\/p>",
