Chile Subnational Administrative Boundaries for Levels 0 to 3

345 administrative units at level 3, 56 at level 2, and 16 at level 1 for Chile. The dataset is part of the Global Subnational Administrative Boundaries collection, contributed and quality assured by OCHA organizations. Boundaries were created in September 2018, with a review for accuracy completed in February 2025.

Use Cases

• Create thematic maps for humanitarian needs assessment based on the hierarchical administrative structure.
• Aggregate statistics to different administrative levels based on the defined boundaries.
• Perform spatial joins for location data based on the provided geospatial polygons.
• Integrate boundaries into a larger global administrative dataset based on its membership in the global collection.

Strengths

• Hierarchical structure with 3 clearly defined administrative levels.
• Part of a standardized global collection (COD-AB), suggesting consistent methodology.
• Multiple file formats (GEOJSON, SHP, XLSX, GEODATABASE) available for different tools.
• Explicit quality review dates, including a review for accuracy in February 2025.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Boundary geometry dates from September 2018; political changes after this date are not reflected.
• Row count is unknown, which may limit suitability assessment.
