Yellow River Basin Reservoir Water Body Maps and Code (1986–2024)

Supplementary materials and code support the manuscript 'Long-term reservoir surface water dynamics in the Yellow River Basin (1986–2024)'. The dataset includes annual reservoir water body distribution maps from 1986 to 2024 derived from 30 m Landsat imagery using the Modified Dynamic Surface Water Extent algorithm in Google Earth Engine. Author Yebin Zou published these materials on figshare under a CC-BY-4.0 license.

Use Cases

• Analyzing long-term reservoir surface water area changes based on annual water body maps from 1986 to 2024
• Reproducing or adapting surface water extraction workflows based on the provided Google Earth Engine JavaScript code
• Conducting visual inspections of reservoir water dynamics using the merged PDF of all annual maps
• Comparing water extraction algorithm results using the supplementary figures that include localized comparisons of DSWE and MDSWE results

Strengths

• Provides a 39-year time series of annual reservoir water body maps from 1986 to 2024
• Includes the complete Google Earth Engine code used to generate the monthly composite surface water maps
• Offers multiple file formats for different uses, including a merged PDF for rapid visual inspection and detailed documentation

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is relatively small at 29.8 MB, which may indicate limited spatial or attribute detail
