Global Annual Urban Dynamics and Green Recovery from 1985 to 2015 at 30-Meter Resolution

Thirty years of global annual urban dynamics and green recovery data from 1985 to 2015, mapped at a 30-meter resolution. The dataset, created by Yinghuai Huang, includes 224 10-degree grid files for urban expansion and green recovery, plus interpreted validation samples for urban extent in 1985 and 2015.

Use Cases

• Modeling long-term urban sprawl patterns based on annual urbanized year data.
• Assessing environmental impact and green recovery efforts based on the green recovery year data.
• Validating remote sensing and data fusion methodologies using the provided interpreted urban extent samples.
• Calculating urban change indices like NUACI using the linked demo code.

Strengths

• Provides a 30-year time series from 1985 to 2015, enabling longitudinal analysis.
• Offers high spatial resolution at 30 meters for detailed mapping.
• Includes validation data (interpreted samples) for accuracy assessment of the mapping approach.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• The dataset's total size and specific file formats for all components are not detailed.
