Delimitation and classification of coastal wetlands: Implications for the environmental management of the Colombian Continental Caribbean Boletín de Investigaciones
Millán,Santiago; Rodríguez-Rodríguez,Jenny Alexandra; Sierra-Correa,Paula.
ABSTRACT This article describes the cartographic layer construction process of Colombian Caribbean coastal wetlands at a scale of 1:100,000 and the results obtained in terms of their quantification and typing. Two cartographic layers were constructed and subsequently joined, one of the permanent water bodies and another of temporary water bodies and associated coverages. The layers were generated by multitemporal analysis of 45 Landsat 8-OLI satellite images, based on the NDVI index, uncertainty models by superposition of cartographic attributes, and a flood frequency consultation model on ALOS PALSAR 1 images. As a result, 576,279 ha of coastal wetlands were delimited (1.9 % of total wetlands in Colombia), of which 20.4 % are within protected areas. The...
