Estudio exploratorio de la calidad ambiental de ambientes urbanos, Caso de estudio de la ciudad de Ibarra

Abstract

Abstract: The objective of this technical project was to explore the environmental quality of the city of Ibarra during the years 2015 to 2022, based on the generation of a quality index urban environment (ICAU) through the processing of Landsat and Bing satellite images; for which three indicators were considered as difference vegetation index normalized (NDVI), land surface temperature (LST) and building density (DC); which were integrated into a weighted linear sum and represented spatially by level of census tracts, as well as were correlated with data socioeconomics for the identification of environmental prioritization areas. The results showed that the environmental quality of Ibarra remained stable in the category of moderate , and that the lowest values ​​of the index, that is, the lowest environmental quality, were evident in the central areas of the city with larger built-up areas, higher temperatures and less surface area of ​​green areas; while, the values higher, better environmental quality, were evident in the peripheral areas towards the limits from the urban area.
