Geoinformatics Heat Hazards Threat Based on Local Climate Zone.

Abstract Sumedang Regency has experienced considerable development in recent times. They started by expanding residential areas and toll roads to construct the Jatigede Dam. Changes in land cover may influence the temperature above and around it. This study aims to analyze the spatial pattern of surface temperature in Sumedang Regency between 2007-2022 based on land cover changes regarding the Local Climate Zone and heat hazard threat. The data used are Landsat TM, Landsat OLI/TIRS, and Landsat OLI-2/TIRS-2 images. The data is taken and processed using Google Earth Engine. The results found an increase in LST from 2007 until 2022, with the most significant increase occurring in 2022. This increase is accompanied by changes in land cover in Sumedang Regency. This increase is accompanied by changes in land cover in Sumedang Regency. Land surface temperatures in Sumedang Regency have continued to increase from 2007 until 2022, and based on the observed urban heat signature, the most significant increase in average temperature occurred from 2007 to 2022 (4.68℃). The strong heat stress category can cause dynamic thermal sensation (DTS), a core-to-skin, and an increase in rectal temperature. Extreme heat stress can cause an increase in rectal temperature time gradient, a steep decrease in total net heat loss, and a steep increase in average sweat rate.
