In this research study, 294 Sentinel 2A satellite images were analyzed for the period 2019-2022, in order to estimate, compare and describe the NDVI and EVI, to know the evolution and dynamics of the vegetation over the Arboretum El Huayo. Arboretum el Huayo is located on UTM coordinates 680729 E, 9576316 N, altitude 122 meters above sea level (masl), which is politically located in the province of Maynas, district of San Juan Bautista, department of Loreto, Peru, and has an area of 18 hectares. The reflectance values were obtained, managed and processed from the collection of images using Google Earth Engine platform. Centroids of pixels per year were using to extract the values of each pixel vegetation indices (606,300 observations in total), subsequently organized chronologically from 2019 – 2022. Our result suggest a statistically significant downward trend in Vegetation Index valu...
