It is derived from a multi\u2011criteria spatial model integrating key environmental and population\u2011related determinants of disease burden, including reclassified land\u2011use exposure factors, water quality indicators, population density, land\u2011based pollution, and air pollution. These factors were combined using a weighted\u2011sum raster overlay to generate a continuous Human Disease Potential surface. The resulting raster was summarised using zonal statistics for each Local Municipality to produce a municipal\u2011level Human_Disease score. Additional capacity\u2011to\u2011cope indicators were joined to the municipal dataset and used to compute a composite Vulnerability_Risk index. The final dataset enables disaster management practitioners, health analysts, planners, and risk professionals to identify municipalities with elevated human\u2011disease vulnerability and incorporate this information into multi\u2011hazard assessments, health\u2011risk planning, early\u2011warning systems, and resource\u2011allocation strategies.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 4148, "latestWkid": 4148, "xyTolerance": 8.98315284119521E-9, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -400, "falseY": -400, "xyUnits": 9.999999999999999E8, "falseZ": 0, "zUnits": 1, "falseM": 0, "mUnits": 1 }, "copyrightText": "Prepared by: Herman Booysen, Principal GIS Scientist / Associate Partner\nOrganisation: SRK Consulting\nAdditional sources:\n\nEnvironmental pollution rasters (air, land)\nWater quality indicators\nPopulation density datasets\nLocal Municipality boundaries\nInternal SRK modelling documentation and multi\u2011criteria analysis methods\nHazard analysis and interpretation findings contained in:\nKZN DRA", "parentLayer": null, "subLayers": [], "minScale": 0, "maxScale": 0, "referenceScale": 0.0, "drawingInfo": { "renderer": { "type": "classBreaks", "authoringInfo": { "type": "classedColor", "colorRamp": { "type": "multipart", "colorRamps": [ { "type": "algorithmic", "algorithm": "esriHSVAlgorithm", "fromColor": [ 76, 230, 0, 255 ], "toColor": [ 255, 0, 0, 255 ] } ] }, "classificationMethod": "esriClassifyNaturalBreaks" }, "field": "Human_Disease", "classificationMethod": "esriClassifyNaturalBreaks", "minValue": 5644.999999999999, "classBreakInfos": [ { "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 76, 230, 0, 255 ], "outline": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 110, 110, 110, 255 ], "width": 0.7 } }, "classMaxValue": 9105.000000000004, "label": "5645.000000 -
