The researchers studied how annual average shorelines can show coastal changes over time more clearly than individual measurements. They used Landsat images from 2000 to 2014 to create these average shorelines. The results showed that annual average shorelines help to see long-term trends in coastal evolution by removing short-term variations. They found that these average shorelines are located about 4 to 5 meters further out to sea compared to more precise measurements.
