Correlation between Land Surface Temperature and Vegetation Greenness using Multi-temporal Images

Abstract

Urban areas tend to have significant temperature differences with the surrounding area. The city of Bandung is surrounded by mountains and forms the Bandung Basin. Land cover differences between Bandung City and surrounding area caused a temperature differences that can identified with remote sensing imagery. The aim of this research are to analyse the change of land surface temperature and the vegetation greenness level in Bandung Basin using Landsat multi-temporal image also to identify correlation between surface temperature change with greenness level in Bandung Basin. In Bandung Basin, there is an increase in temperature in various land covers (Vegetation in flat areas, Vegetation in steep and high altitude areas, Water, Built-up area, and Open Land area) from 1990-2018. Meanwhile, there is less green vegetation in Bandung Basin from 1990-2018. The results of the analysis show a better correlation between Land Surface Tempertare (LST) and Simple Ratio Index (SRI) than the correlation between Land Surface Tempertare (LST) and Normalized Difference Vegetation Index (NDVI). The conclution of this research that preservation of vegetated areas can be done in Bandung Basin to address the increasing of Land Surface Temperature.

Pemanfaatan Citra Landsat 8 Untuk Pemetaan Sebaran Dan Kerapatan Ekosistem Mangrove Di Kecamatan Cijulang Kabupaten Pangandaran

“…Indeks merupakan transformasi spektral yang diterapkan pada gambar multi-saluran dengan tujuan untuk menyoroti aspek vegetasi seperti kepadatan dan konsentrasi klorofil. Indeks vegetasi dibentuk oleh kombinasi beberapa nilai spektral yang ditambahkan, dibagi, atau dikalikan untuk mendapatkan nilai yang menyatakan jumlah vegetasi per piksel (Himayah et al, 2019). Metode yang digunakan dalam penelitian persebaran hutan mangrove ini adalah interpretasi citra penginderaan jauh secara visual, Normalized Difference Vegetation Index (NDVI), dan Modified Soil and Atmospheric Resistant Vegetation Index (MSARVI).…”

“…LST is the remote sensing derived using satellite imageries with thermal infrared band [7], [8]. Remotely sensed LST was selected due to wide areal cover.…”

Statistical modeling for land surface temperature in Borneo island from 2000 to 2019

“…This situation has changed the land surface characteristic and spatiotemporal pattern of urban heat island which is designated by LST (Li et al 2012). Some parts of Southeast Asia such as Kalimantan in Indonesia, East Malaysia and Brunei Darussalam have experienced land-use changes, mainly for oil palm cultivation (Gunarso et al 2013) (Himayah et al 2019;Hua and Ping 2018). In other Southeast Asian countries, such as Thailand, the mean daily maximum temperature, is predicted to increase by 1.2 to 1.9 °C by 2050 (Marks 2011).…”
