Using Continuous Change Detection and Classification of Landsat Data to Investigate Long-Term Mangrove Dynamics in the Sundarbans Region

Katie Awty-Carroll, Pete Bunting, Andy Hardy, Gemma Bell
2019 Remote Sensing  
Results showed that while mangrove extent in the Sundarbans has remained stable, around 25% of the area experienced an overall negative trend, probably due to the effect of die-back on Heritiera fomes.  ...  To demonstrate the utility of this approach, CCDC was applied to a 30-year time series of Landsat data covering an area of mangrove forest known as the Sundarbans.  ...  First training data was obtained using the Global Mangrove Watch (GMW) Version 2.0 dataset. The GMW provides a highly accurate global mangrove baseline for 2010 [2] .  ...
