A fine resolution mangrove map of China for 2019 derived from 10-m-resolution satellite observations and Google Earth images
With the field surveys and communications with mangrove experts, the previous version of mangrove map in China for 2019 had the omission problem that some mangrove patches were missing in the product. A mangrove map using an image interpretation and field investigation approach was then released. This mangrove map was checked by field survey in some areas, thus can be a reference to update the previous version of mangrove map. A new mangrove map was derived by integrating existing data sets, eliminating the misclassified patches, and repairing the missing mangrove patches. Based on an evaluation sample dataset (the data was in doi:10.11922/sciencedb.00279), the overall accuracy reached 97.0 ± 0.2%. The accurate rate in metrics of 1096 field sample plots was 96.7%. The total area of mangroves in China in 2019 is estimated to be 27053.07 ha under the asia north albers equal area conic projection, which is highly consistent with the rresult of the third national land survey. This dataset provides a basis for mangrove protection, restoration, and management in China, mangrove related carbon sink estimation, and related studies in China.
