{ "currentVersion": 10.91, "cimVersion": "2.9.0", "id": 3, "name": "Heat Risk", "type": "Feature Layer", "description": "

The Heat Risk layer combines data from the Heat Vulnerability and Heat Exposure layers to provide a comprehensive assessment of areas in San Diego most susceptible to the adverse effects of urban heat. By integrating socio-demographic indicators with land surface temperature data, this layer offers a nuanced view of heat risk across the city, serving as an essential tool for prioritizing public health measures and urban planning initiatives aimed at mitigating heat-related impacts.<\/SPAN><\/P>

<\/P>

The Heat Risk layer utilizes the \"Heat_Risk\" field and is symbolized using quantile breaks to categorize and visually represent different levels of heat risk throughout San Diego. This method allows for a clear distinction between areas of varying risk, aiding in the identification of regions requiring immediate attention and intervention.<\/SPAN><\/P>

Urban Heat Index Fields:<\/SPAN><\/P>

- GEOID: Census block group identifier.<\/SPAN><\/P>

- Heat_Vulnerability: Score indicating social vulnerability to heat.<\/SPAN><\/P>

- Heat_Exposure: Score representing heat magnitude based on surface temperatures.<\/SPAN><\/P>

- Heat_Risk: Combined score of heat exposure and vulnerability.<\/SPAN><\/P>

- Census_Tract: The census tract number.<\/SPAN><\/P>
