    The degradation of wetlands impacts the ecosystem services they provide, especially the capacity for water regulation and flood control, which is considered by Ricaurte, et al. (2017) as one of the most important services provided by these ecosystems. As a result of this problem, studies have been carried out in the aforementioned ecosystems, in order to know the location of wetlands and support land-use planning and disaster prevention policies in the departments and municipalities of the country (Patiño, 2016). As a consequence of the degradation suffered by these ecosystems in Colombia and the lack of an updated and accurate inventory, several authors agree that the delimitation at a precise and detailed scale of wetlands is a fundamental and necessary tool to establish strategies for the preservation, protection and conservation of their ecosystem services; especially for the preservation of their water regulation conditions (Baker, C. et al., 2006), (Brena, Castillo, and Wagner, 2016), (Patiño, 2016). Therefore, the general objective of this work is to know the spatial variation of the Bajo Sinú Cenotage Complex during its seasonal periods for the year 2021. The methodology employs the use of PlanetScope satellite images through spectral indices, with the purpose of establishing a categorization of the spectral ranges of the different analysis coverages present in the Lower Sinú swamp complex and, in this way, to verify the individualization capacity of these study classes. In response to the methodology used and the results obtained, it was possible to generate a cartography of the different coverages associated to the CCBS at a higher level of detail than the one usually used (1:10 000), as well as the calculation of the total areas of the wetlands corresponding to the complex, including their floating aquatic vegetation coverages.
