The general objective of this study is to contribute to the actual and future acknowledging of the coastline dynamics of a portion of the WestCameroon coast using Landsat satellite images 3, 7 and 8 from 1979 to 2018. To achieve this objective, the images were pre-treated through atmospheric corrections using the ENVI 5.1 software, which enabled the digitalization of the coastlines of the study zone in the different images using the ArcGIS version 10.1 software and then the statistical computation of the speeds of evolution of the coastline at different dates was done using DSAS version 4.3. The main results obtained show two evolutionary trends of coastal linear interest: in the long term, the study has given a decline in the coastline of ...
