Heat vulnerability mapping involves identifying areas that are most vulnerable to the impacts of extreme heat events. Here are the steps to create a heat vulnerability map using ArcGIS:

Collect Data: The first step is to gather relevant data for the analysis. This includes climate data (e.g., temperature, humidity), topographic data (e.g., elevation, slope), land cover data, and socio-economic data (e.g., population density, poverty levels).

Preprocessing Data: After collecting the data, the next step is to preprocess the data. This involves converting the data into a common format and projecting the data into a common coordinate system. It may also involve cleaning and filtering the data to remove errors or inconsistencies.

Analyze Data: The next step is to analyze the data. This involves using GIS tools to identify areas that are most vulnerable to the impacts of extreme heat events. There are several methods that can be used to identify vulnerability, including:

Overlay Analysis: Overlay analysis can be used to combine different layers of data to identify areas that have high levels of vulnerability. For example, you can overlay layers of temperature, humidity, and land use to identify areas that are most vulnerable to the impacts of extreme heat events.

Suitability Analysis: Suitability analysis can be used to identify areas that are most suitable for certain activities, such as living or working. For example, you can use suitability analysis to identify areas that are most suitable for outdoor activities during hot weather.

Regression Analysis: Regression analysis can be used to identify relationships between different variables, such as temperature and socio-economic status. This can help identify areas that are most vulnerable to the impacts of extreme heat events.

Visualize Data: Once the data has been analyzed, the next step is to visualize the results. This can be done by creating heat maps, choropleth maps, or other types of maps that show the distribution of vulnerability across the study area.

Interpret and Communicate Results: The final step is to interpret the results and communicate the findings to stakeholders. This can involve identifying areas that are most vulnerable to the impacts of extreme heat events and developing strategies to reduce vulnerability and mitigate the impacts of extreme heat. It is also important to engage stakeholders throughout the process to ensure that the heat vulnerability map is relevant and useful for decision-making.

You can process MODIS data using GIS. You can do research on Landsat8 data, one of the band on Landsat8 too may give you temperature data. Processing the data to generate maps is very easy using GIS.

Heat vulnerability mapping involves identifying areas that are more susceptible to the impacts of high temperatures and extreme heat events. Here are the steps to create a heat vulnerability map in ArcGIS:

Data required for heat vulnerability mapping may include:

• Demographic data such as population density, age, income, and race/ethnicity.
• Land use/land cover data, including impervious surfaces and green spaces.
• Climate data such as temperature and humidity.
• Topographic data such as elevation and slope.
• Health data such as hospitalization rates for heat-related illnesses.

It is important to note that the specific data required may vary depending on the location and the goals of the mapping project.
