Abstract
This work shows a study carried out in the upper area of the Chaschuil Valley in the South Ramsar Subsidy of the province of Catamarca for the identification of wetlands through the analysis of SRTM and LANDSAT images. Factors influencing the use of wetlands, such as size, fertile plains, water dynamics and associated vegetation, were considered. The image processing of the Landsat 8 satellite (PATH-ROW = 232-079) was carried out, as well as the sampling data of the January 2019 campaign. Base maps were generated and analysis of geographic information system (GIS) to classify water bodies. The results allowed us to better understand the relationship between the geomorphology of the basin and its water dynamics and allow us to advance in the study of wetlands of importance to the ecosystem of the region.
