Mozambique Floods 2026: Building and Road Data for Gaza and Maputo

Geospatial building footprints and road networks for the Gaza, Maputo, and Maputo City provinces of Mozambique were mapped by over 2,300 Humanitarian OpenStreetMap Team (HOT) volunteers starting in January 2026. Developed in coordination with UNICEF and INGD, the data supports disaster response for the GLIDE FL-2026-000004-MOZ flooding event.

Use Cases

• Assessing structural damage by intersecting 'Buildings' layers with flood extent maps
• Routing humanitarian aid using the 'Roads' network in Gaza and Sofala provinces
• Quantifying urban density in Chicumbane to estimate affected populations using building footprints

Strengths

• Over 2,300 unique contributors
• Priority areas defined by UNICEF and INGD
• Based on Copernicus EMSR857 flood extent data

Limitations

• Volunteer-contributed data may contain varying levels of attribute accuracy
• Mapping is ongoing and may not yet cover all northern settlements
• Bi-weekly update frequency may lag behind rapid ground changes
