Information on Shoreline Monitor
The viewer displays the long-term shoreline change rates based on linear regression at 500m spaced transects along the entire world's shoreline. The shoreline change rates are displayed for both sandy and non-sandy coasts. At the moment we validated the shoreline detection method for sandy beaches only; see the paper for the four validation sites. The global analysis presented in the paper focuses on sandy beaches, which thus covers a selection of the entire shoreline data set.
Nevertheless, we decided to also present the non-sandy shoreline changes although not yet validated. It is an unattainable goal to perform a quality assurance for each of the 2.2 million transects presented in this webviewer. Therefore, it would be great if could share your feedback or comments with us in case you have noticed some mistakes or inconsistencies.

Furthermore, the viewer only presents the annual shoreline positions for each transect. These positions were derived from the underlying high-frequent shorelines (based on revisit times of 2-16 days) that have an alongshore resolution of 30 m and global coverage. While the annual shorelines provide max 33 shoreline positions in the period 1984 - 2016, the high-frequent shorelines typically results in 500 - 800 shoreline positions depending on the location and cloud coverage.
