Supplementary Code Data: Urban Expansion Analysis for Jakarta and Taipei, 1990–2020

1990–2020 urban expansion dynamics for the Jakarta and Taipei metropolitan regions. The dataset contains processed built-up area and population grids, harmonized land-use classification tables, derived spatial metrics, and analytical scripts supporting a comparative study. It was created by Helen Dian Fridayani and last updated on 2026-06-01.

Use Cases

• Quantifying built-up expansion and population density changes based on processed GHSL and national land-use data.
• Analyzing land-source conversion patterns and urban sprawl metrics like normalized Shannon entropy.
• Calculating Sustainable Development Goal (SDG) Indicator 11.3.1 for comparative urban sustainability assessment.
• Reproducing spatial analyses, including expansion directionality and spatial autocorrelation (Moran's I), using provided GIS workflows.

Strengths

• Integrates data from two distinct metropolitan regions (Jakarta and Taipei) for cross-national comparison.
• Derived from authoritative public sources including the European Commission Joint Research Centre's GHSL and national governmental agencies.
• Includes analytical scripts and workflow documentation supporting full reproducibility of the study's results.

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 very small (9.9 KB), indicating it contains processed outputs and code rather than raw source data.
