Detección de cambios en la morfología litoral de Punta Zacatal y parte occidental de Isla del Carmen, Campeche, mediante el análisis multitemporal de imágenes de satélite

During the last 25 years. significant geomorphological changes have been detected in the coastiline of Punta Zacatal and the western region of isla del Carmen, Campeche, as consequence of the current littoral dynamics and the influence of urban and industrial development. In order to detect such...
