Analyses of Short- and Long-Term Shoreline Trends of the Southwest Benin Coast

Monitoring Coastline Dynamics Using Satellite Remote Sensing and Geographic Information Systems: A Review of Global Trends

“…As the spatial resolution of Landsat improved with new generations of satellite sensors, researchers found it to be an increasingly useful tool for assessing coastal changes. On the other hand, Sentinel imagery, with a 10 m foot-print, was used to extract coastal features using the high-water line (Balle et al, 2021;Waghmare et al, 2020). SPOT-4 images taken between 2006 and 2011 were used to quantify coastline changes along the Damietta promontory coast in Egypt (El-Asmar et al, 2014).…”

“…Automatic Coastline extraction using edge detection Detection of high-water lines using spatial filtering is a very important approach for automatic shoreline mapping and has been utilized by several researchers (Paravolidakis et al, 2018;Balle et al, 2021;Adnan et al, 2016).…”

“…Conversely, erosion affected 31% of the coastline, occurring at an average rate of 0.7 meters per year. The majority of this erosion was concentrated near the mouth of the Bouche du Roy estuary (Balle et al, 2021).…”

“…Any long-term study of a coast should start with aerial photography (Chaaban et al, 2012;Stéphan et al, 2019). The availability, repetitiveness and affordability of medium spatial resolution satellites such as Landsat, SPOT and Sentinel make their imagery products an attractive choice for studying coastline dynamics (Carvalho and Guerra 2020;Balle et al, 2021). Landsat was launched in 1972, taking it the satellite with the longest record of continuous imagery.…”
