Description: <DIV STYLE="text-align:Left;font-size:12pt"><DIV><DIV><P><SPAN>The Heat Exposure layer in the Urban Heat Index represents the intensity of heat across San Diego by analyzing land surface temperatures derived from satellite data. Symbolized using quantile breaks, this layer vividly delineates areas by their heat exposure levels, providing a critical tool for urban planners and public health officials to identify high-risk areas and implement cooling measures.</SPAN></P><P><SPAN /></P><P><SPAN>The Heat Exposure layer is symbolized using quantile breaks based on the "Heat_Exposure" field, effectively categorizing areas by their relative heat levels. This approach allows for a clear visualization of heat distribution across San Diego, highlighting regions with elevated heat exposure and aiding in targeted response strategies.</SPAN></P><P /><P><SPAN>Urban Heat Index Fields:</SPAN></P><P><SPAN>- GEOID: Census block group identifier.</SPAN></P><P><SPAN>- Heat_Vulnerability: Score indicating social vulnerability to heat.</SPAN></P><P><SPAN>- Heat_Exposure: Score representing heat magnitude based on surface temperatures.</SPAN></P><P><SPAN>- Heat_Risk: Combined score of heat exposure and vulnerability.</SPAN></P><P><SPAN>- Census_Tract: The census tract number.</SPAN></P><P><SPAN /></P><P><SPAN>Geographical Coverage: City of San Diego, California</SPAN></P><P><SPAN>Temporal Coverage: 2015-2020</SPAN></P><P /><P><SPAN>Contact:</SPAN></P><P><SPAN>City Planning Department </SPAN></P><P><SPAN>619-235-5200</SPAN></P><P><SPAN>planning@sandiego.gov</SPAN></P><P><SPAN>202 C Street, M.S. 413</SPAN></P><P><SPAN>San Diego, CA 92101</SPAN></P><P><SPAN /></P><P><SPAN /></P></DIV></DIV></DIV>
