Coastal Wetland Restoration Maps and Data from 69 Global Sites

69 GeoTIFF classification maps at 30-meter resolution, derived from Landsat 5/7/8 imagery, support a study on coastal wetland restoration trajectories. The dataset includes source Excel files with site-level attributes and R scripts for statistical analysis, authored by Junlin Ren and last updated in April 2026. It is shared under a CC-BY-4.0 license.

Use Cases

• Classifying tidal wetland land cover (vegetation, mudflat, water) based on the provided pixel values in the GeoTIFFs.
• Analyzing site-level drivers of wetland change based on variables like tidal_wetland_extent_change_rate and total_suspended_matter.
• Reproducing statistical models and figures from the associated study using the provided R analysis scripts.
• Mapping the global distribution and status of coastal wetland restoration sites based on geographical coordinates and compositional attributes.

Strengths

• Includes 69 distinct geospatial classification maps for multiple study sites.
• Data has a defined 30-meter spatial resolution and uses the standard WGS 84 coordinate system.
• Source data and analysis code are provided, supporting reproducibility.

Limitations

• Row count and detailed column-level documentation are unknown, requiring inspection after download.
• The dataset is small (1.8 MB), which may limit the scale of analysis possible.
