Madagascar - Shoreline (EO4SD-Marine)

This layer consists of data used to map shoreline change rates in Madagascar produced by the National Oceanography Centre for the Marine and Coastal Resources project under the initiative Earth Observation for Sustainable Development (EO4SD) by the European Space Agency. Geodatabase contains:

• Admin boundary - administrative boundary of coastline
• Madagascar Shorelines - Each shoreline delineated from the 20-year period
• Forecast 10 [years]
• Forecast 20 [years]
• Forecast Uncertainty 10 [years]
• Forecast Uncertainty 20 [years]
• Shoreline change rates - transects

Historical shorelines between 2000-2020 can be visualised, created by annual median composites of Landsat 7 and 8 imagery which delineates the approximate mean high water mark. Methods are inspired by Coastsat, a Google Earth Engine-enabled open-source software toolkit that delineates shorelines at any sandy coastline worldwide from over 30 years of publicly available satellite imagery (https://github.com/kvos/CoastSat).
