Variabilidad en la correlación lineal de la temperatura superficial terrestre (LST) y los índices espectrales utilizando imágenes de satélite. Caso de estudio : Ciudad de Bogotá, Colombia

Abstract

This research aims to evaluate the variability of the linear correlation between land surface temperature (LST) and the spectral indices NDVI, NDWI, NDBI and NDBaI in the between land surface temperature (LST) and the spectral indices NDVI, NDWI, NDBI and NDBaI in the urban area of Bogota, Colombia Bogotá, Colombia during the time period from 1997 to 2022. There would be three variables: three indices and the temperature three variables: three indices and temperature, being the dependent SWIR and the independent ones the others. others. The data would be annual, between 1997 and 2022. This is due to the fact that climate variations are not as significant as in 1997 and 2022. variations are not as significant as in regions where the stations are located. In addition, there is a shortage of images. Methodologically, it will have a qualitative-quantitative approach, and for the information collection and processing will use the Google Earth Engine -GEE- platform and MiraMon software, which will be used and the MiraMon software, which offers the advantages of facilitating the calculation of spectral indices, using the Raster reclassification tool, and the the Raster reclassification tool, and the calculation of the multiple regression coefficient.
