Mapping Heat Risk Index: A Tool for Climate Action

-


 As global temperatures rise, urban areas are experiencing more frequent and intense heatwaves, posing serious risks to human health, infrastructure, and ecosystems. To address this growing challenge, Heat Risk Index (HRI) mapping has emerged as a vital tool for assessing and mitigating heat-related impacts.

What is a Heat Risk Index?

A Heat Risk Index combines multiple factors such as land surface temperature, vegetation cover, population density, and socio-economic vulnerability to identify areas most at risk during extreme heat events. By integrating GIS, remote sensing, and spatial analysis, HRI mapping provides a visual representation of heat exposure across different regions.

Why is HRI Mapping Important?

  1. Identifies High-Risk Zones : Helps policymakers and urban planners to pinpoint areas that needs heat mitigation strategies, such as tree planting, reflective surfaces, and cooling centers.

  2. Supports Public Health Initiatives : Assists health agencies in targeting vulnerable communities, including the elderly and low-income populations, who will potentially impated by extreme heat.

  3. Enhances Climate Adaptation: Provides data-driven insights to improve urban design, land use planning, and disaster preparedness.

How is HRI Mapping Done?

HRI mapping integrates data from satellite imagery (e.g., Landsat, MODIS), ground temperature sensors, and demographic datasets to generate heat risk assessments. GIS-based modeling helps visualize patterns, allowing decision-makers to develop localized solutions for heat resilience.

Heat Risk Index mapping will play a crucial role in urban resilience planning. By leveraging spatial data and analytics, cities can implement proactive strategies to reduce heat stress and protect communities from extreme weather events.

  NDVI Mapping Using ArcGIS Pro Normalized Difference Vegetation Index (NDVI) is a powerful remote sensing tool used to assess vegetation health, monitor changes in land cover, and support environmental management decisions. NDVI uses satellite data to distinguish healthy vegetation from other surface types based on how they reflect light. ArcGIS Pro provides an excellent platform for performing NDVI analysis with its robust set of spatial tools and geospatial capabilities.   Steps to Map NDVI Using ArcGIS Pro          ·             First, we need multispectral satellite images, ideally from Landsat or Sentinel-2 satellites. The key bands for NDVI calculation are the Near-Infrared (NIR) and Red bands.          ·             Open ArcGIS Pro and load the multispectral data into projec...

  Hot-spot analysis of median income using census block-group-level data and Getis-Ord Gi* statistic  (ArcGIS Pro) The Getis-Ord hot spot analysis shows where high and low values are clustered. The tool compares the values of each feature with the neighboring features within a user specified distance. The values for each feature are then color coded to show high and low value clusters. The Gi statistic, also called Gi*, used both the location and the value in the pattern calculations. This is used to see the effect of the value field on the clustering over the user specified distance. The distance is determined by the characteristics of the input dataset. Features representing large, wide groupings may use a larger distance band value, while features representing a local region or smaller feature areas might use a small distance band value. With a larger value, expect to get a few large clusters. A smaller distance value may result in more numerous, smaller clusters.
