Global Urban Land Projections by SSP Scenarios, 2000-2100

Global One-Eighth Degree Urban Land Extent Projection and Base Year Grids by SSP Scenarios provides global urban land fraction data for 2000 and decadal projections from 2010 to 2100. The dataset uses a data-science approach integrating 15 diverse data sources, including a 40-year Landsat time series, to create SSP-consistent spatial distributions. It was developed by ESDIS to support climate change research and IPCC assessment reports.

Use Cases

• Modeling future land-use change under different Shared Socioeconomic Pathways (SSPs).
• Assessing climate change vulnerability and adaptation strategies using urban extent grids.
• Analyzing historical and projected urban growth patterns at a one-eighth degree resolution.
• Providing key inputs for integrated assessment models studying energy use and emissions.

Strengths

• Integrates 15 diverse datasets, including a 40-year global Landsat time series, for empirical grounding.
• Provides consistent decadal projections from 2000 to 2100 across multiple SSP scenarios.
• Offers a fine spatial resolution of one-eighth degree (7.5 arc-minutes) for global analysis.

Limitations

• Critical metadata conflicts exist: the 'last updated' date is reported as both 2100-12-31 and 2026-03-13 across platforms.
• Specific column names, row counts, and file sizes are not provided by any source.
• The dataset's license and precise authorship details are unknown.
