Create an Urban Heat Island Profile Using ArcGIS Online

This video tutorial guides viewers through the process of investigating urban heat islands using ARC GIS Online. It explains the urban heat island effect and provides step-by-step instructions on creating an urban heat island profile for a city. The tutorial covers setting up an ARC GIS account, navigating the map viewer, adding and exploring data layers, defining transects, and collecting data. It concludes with instructions on analyzing the data to understand the relationship between surface type, tree canopy cover, and temperature.
