Sub-meter Mangrove Spatial Distribution Dataset of China in 2020

However, mangrove ecosystems have long been disturbed by human activities and natural disasters, making accurate monitoring and long-term tracking of mangrove changes particularly important. Existing large-scale mangrove mapping products typically have spatial resolutions of 10 meters or 30 meters.

While these studies have made significant progress in advancing mangrove monitoring and conservation, they still face challenges, including inaccurate boundary identification, difficulty in extracting internal details, and issues with detecting small patches. To address these challenges, this dataset employs a novel Semi-automatic Sub-meter Mapping Method (SSMM). The method enhances the spectral separability between mangroves and other land cover types by selecting nine key features from Sentinel-2 and Google Earth imagery.
