Generación de un índice ecológico de teledetección (RSEI) para estimar la calidad ambiental de Zipaquirá en el periodo 1998-2023

Abstract

This study focuses on the generation of a Remote Sensing Ecological Index (RSEI) to estimate the environmental quality of the municipality of Zipaquirá. For this purpose, satellite images from the Landsat 5 TM, Landsat 7 ETM+, Landsat 8 OLI/TIRS and Landsat 9 OLI 2/TIRS 2 missions were used. The methodology was structured into three specific objectives: the delimitation and processing of images, which includes the delimitation of the study area, acquisition of images in Surface Reflectance (SR) and Top of Atmosphere (TOA) products, digital processing and generation of the Remote Sensing Ecological Index; the evaluation of results through spatial autocorrelation analysis and application of local and global indices; and the verification and comparison of results with previous studies to ensure the validity and accuracy of the RSEI. The development of this study is vital to apply a Remote Sensing Ecological Index, which allows obtaining an estimate of the environmental quality of the municipality of Zipaquirá, in the period from 1998 to 2023.
