Mozambique - Floods - January 2026 - OpenStreetMap Data

This dataset contains OpenStreetMap data exported from the HOTOSM disaster mapping response to Tropical Cyclone Gezani in early 2026 (GLIDE: TC-2026-000015-MDG ). On Tuesday the 10th of February, Tropical Cyclone GEZANI 26 made landfall near the city of Toamasina on the eastern coast of Madagascar as Category 4 cyclone. The cyclone severely damaged homes leading to massive displacements, caused fatalities and injured many. HOT is working in collaboration with Madagascar OSM Community, Malagasy Red Cross, and INGD (Mozambique Disaster Risk Management Institute) to prioritise and coordinate the mapping response. The data has been contributed by volunteers through the Humanitarian OpenStreetMap Team's Tasking Manager and represents buildings and roads in the affected area. It is updated weekly as mapping progresses. Subscribe to this dataset to be notified of any new updates. This dataset includes all OpenStreetMap features in the area of interest for this event, covering: Buildings and Roads. See the list of projects in the Tasking Manager here. For more information see the HOTOSM activation page. As of 27 April 2026: over 2,000 contributors (non unique).

Building footprints across the area: every feature tagged `building=*`, from residential homes to hospitals, schools, and places of worship. Useful for population estimation, damage assessment, and urban planning. Coverage reflects where volunteer mappers have been active. Urban areas are usually well represented, remote areas may be sparse. Cross-check critical decisions with local field knowledge. - Source: OpenStreetMap, a free, collaborative world map - Tags: building - Part of the country exports on HDX by HOT

Buildings Existing Before the May 2024 Rio Grande do Sul Floods. This dataset contains buildings and destroyed buildings mapped as part of the HOTOSM Rio Grande do Sul Floods Activation mapping project.

Road network across the area tagged `highway=*`: motorways, residential streets, service roads, footways, and trails. Useful for routing, accessibility analysis, and evacuation planning. Coverage reflects where volunteer mappers have been active. Urban areas are usually well represented, remote areas may be sparse.

Water features across the area: rivers, streams, canals, lakes, ponds, and water bodies tagged with `waterway`, `water`, or `natural=water`. Useful for flood-risk modelling, watershed analysis, and environmental basemap context. Coverage reflects where volunteer mappers have been active. Urban areas are usually well represented, remote areas may be sparse.
