Annual coastal wetland vegetation maps of the Yangtze Estuary from 1986 to 2021

Basic information

Using remotely sensed data from Google Earth Engine, we generated a 30 m resolution annual dataset of Yangtze Estuary wetland vegetation for the period 1986-2021. This dataset includes three dominant vegetation types (Spartina alterniflora, Phragmites australis, and Scirpus mariqueter) and tidal flat areas. We combined fieldwork data and high-resolution images for accuracy assessment, achieving an overall accuracy exceeding 80% in different years. Detailed information about the mapping methods can be found in our paper and accompanying supplementary materials.

Notes:

In the image classification scheme: 0-Tidal flats, 1-Spartina alterniflora, 2-Phragmites australis, 3-Scirpus mariqueter.

Usage Policy:

This dataset is a collaborative effort between East China Normal University and Deakin University. If you plan to use our data in a scientific analysis paper or other research work, we strongly recommend contacting us in advance to seek our opinions, citing the unique DOI of this dataset, and considering acknowledging our contributions or including us as co-authors.
