Madagascar - Tropical Cyclone Gezani - OpenStreetMap Data

This dataset contains OpenStreetMap data exported from the HOTOSM disaster mapping in response to flooding events in the Gaza, Maputo and Maputo City Provinces of Mozambique (GLIDE: FL-2026-000004-MOZ) in early 2026. Severe flooding in Mozambique has affected more than half a million people following heavy rains in the first weeks of the new year. Gaza province has been hit hardest, alongside Maputo and Sofala provinces. The first OSM extract was based on Copernicus' flood extend from 29 January 2026. The first disaster response mapping project focused on settlements around Chicumbane in the Province of Gaza which, from 9 February, expanded to other settlements in the province. It now includes additional settlements further north in the Province. HOT worked with UNICEF, INGD (Mozambique Disaster Risk Management Institute) and OSM Mozambique to define priority areas and features. 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 was updated once or twice a week as mapping progresses but is now updated every other week. 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, Roads. See the list of projects in the Tasking Manager here. For more information see the HOTOSM activation page. As of 22 April 2026: over 3,300 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

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.
