Interpretación de la dinámica de la vegetación durante la época seca en la ciénaga del Totumo (Piojó, Atlántico), a partir del cálculo del índice de vegetación normalizada (NDVI) y análisis multitemporal a imágenes Landsat 8 de los años 2014 a 2020

Abstract: The normalized vegetation index NDVI (Normalized Difference Vegetation Index) was calculated from Landsat 8 images (2014 to 2020) for the general environment (EG) and the area of direct influence (AID) of the Totumo swamp (Piojó, Atlántico) using the Geographic Information System (ArcGIS 10.5). The vegetation cover for the period analyzed, both in the EG and in the AID, describes periods where the higher vegetal classification categories (NDVI value > 0.2), present a higher percentage of cover and periods when the lower classification categories (≤ 0.2) presenting a higher percentage of vegetation cover. The largest vegetation cover during the study period was presented for the year 2020; however, this increase in vegetation cover category 2, which found inside the body of water, suggests an increase in the sedimentation of the swamp that has been colonized by some type of vegetation with photosynthetic activity.
