Developed as part of the Tomorrow's Cities GCRF Urban Disaster Risk Hub project for risk-informed decision making in urban planning. details: 'The dataset includes: (i) 100-year return period flood hazard as vector point grid (127,422 point features) with water depth (IM) values in GeoJSON format, plus flood depth-damage vulnerability functions for 6,300 building typologies at 9 water depths (0-6m) in JSON columnar format; (ii) five future exposure dataset variants representing different community planning scenarios, each containing building footprints (5,815 buildings, 116 typologies in MultiPolygon geometry) with structural taxonomy, household data, individual demographics, and land use plans (110 zones, 25 categories); and (iii) flood impact results per scenario including building damage states, impact metrics, and nearest road node connectivity. Note: Only flood hazard is present despite the Multi Hazard Dataset naming. No road, power, or other infrastructure data in exposure datasets.' exposure: category: buildings, economic_indicator, population dimension: population, structure quantity_kind: area, count, currency taxonomy: GED4ALL extra_attributions: - email: press@ukri.org id: attribution_funder name: Natural Environment Research Council (NERC) role: funder url: https://www.ukri.org/councils/nerc/ - email: servicedesk@ucl.ac.uk id: attribution_collaborator name: University College London role: collaborator url: https://www.ucl.ac.uk/ hazard: calculation_method: simulated disaster_identifiers: '' hazard_analysis_type: probabilistic hazard_type: flood intensity: wd:m occurrence_range: '' processes: fluvial_flood seasonality: '' license: CC0-1.0 loss: approach: '' base_data_type: '' category: '' description: Affected population results from flood impact assessment for each community planning scenario., Building damage state results from flood impact assessment for each community planning scenario (Business, Elders, Women, Youth1, Youth2). dimension: '' exposure_id: '' hazard_analysis_type: '' hazard_id: '' hazard_process: fluvial_flood hazard_type: flood impact_metric: '' impact_type: '' impact_unit: '' type: '' vulnerability_id: '' project: name: Tomorrow's Cities - GCRF Urban Disaster Risk Hub url: https://tomorrowscities.org/ publisher: email: support@tomorrowscities.org id: attribution_publisher name: Tomorrow's Cities url: https://data.tomorrowscities.org/ purpose: To support flood risk assessment and risk-informed urban planning decision making for Nairobi by providing spatial hazard, synthetic future exposure, vulnerability functions, and impact assessment datasets for participatory community planning scenarios. resources: - coordinate_system: EPSG:4326 description: 'Flood hazard dataset containing: (1) 100-year return period flood depth GeoJSON (127,422 point features with IM/depth values); (2) Flood depth-damage vulnerability functions for 6,300 building typologies in JSON columnar dict format.
