Vegetation Greenness Changes and Land Surface Temperatures Monitoring in the Bandung City, West Java

Abstract

Remote sensing can be used to examine the city of Bandung with variations in its topographical appearance. Apart from that, urban areas such as Bandung generally experience land cover transformation (vegetation and non-vegetation) as well as changes in land surface temperature. This research aims to: 1) Analyse vegetation greenness in the Bandung City, 2) Analyse land surface temperature in the Bandung City, and 3) Analyse the correlation between vegetation greenness changes with dynamics of land surface temperature in the Bandung City. The method used is information extraction through remote sensing imagery to obtain changes of vegetation greenness and dynamics of land surface temperature, as well as field measurements. This research use Landsat 5 and Landsat 8 to get a value of built-up index and vegetation greenness. The results of this research are the identification of the spectral character of vegetation greenness, as well as their influence on land surface temperatures in the Bandung Basin. Types of vegetated land use, including rice fields, parks and plantations, have lower temperatures than settlements, roads, empty land and cemeteries. Positive values in the regression results indicate a correlation between the NDVI and LST variables.
