Short summary
We introduce CCAV-10m, an annual, species-level 10m resolution coastal wetland vegetation dataset for eastern China. It was produced using a novel phenology-guided vegetation classification network that integrates Sentinel-1/2 satellite imagery with field observations. Validation demonstrates strong classification accuracy (overall accuracy: 0.916, Kappa: 0.898). Regular updates will support long-term coastal wetland research, invasive species monitoring, and precision wetland management.
