Abstract -
This study on the cartography of shoreline evolution presents a diachronic analysis of the evolution of the shoreline near the Baguida and Agbodrafo cantons of 1986 and 2017 by photo-interpretation. The problem underlying the study is the spatial and temporal dynamics of the coastline of the Baguida-Agbodrafo sector. She uses as references the instantaneous shore line. This evolution has been mapped and quantified from Landsat images exploited with the DSAS and MobiTC tools. The observed variations in the position of the instantaneous shoreline between 1986 and 2017 indicate a shoreline eroding at a high rate of about -3 m / year. These developments have not been continuous. In some points opposing dynamics could be observed.
