Flood Hazard Zoning for 36 Colombian Population Centers at 50-Year Return Period

36 population centers in Colombia have flood hazard zones mapped for a 50-year return period. The data, published by www.datos.gov.co, classifies areas into low, medium, or high threat levels. It was last updated on 2026-05-22, though the description notes updates are occasional and the raw data is not validated by IDEAM.

Use Cases

• Classifying flood threat levels (Amenaza) for specific population centers (CENPOB) using geospatial boundaries (the_geom).
• Calculating total area at risk (AREA_TOT, SHAPE_AREA) per municipality (MUNICIPIO) or department (DEPARTAMEN).
• Analyzing the distribution of hazard classifications (Amenaza) across different geographic regions (DEPARTAMEN).

Strengths

• Geospatial data (the_geom) with explicit hazard classification (Amenaza) for 36 distinct locations.
• Includes administrative metadata such as municipality (MUNICIPIO) and department (DEPARTAMEN) for regional analysis.
• Provides geometric attributes (SHAPE_LEN, SHAPE_AREA) for quantitative spatial calculations.

Limitations

• The description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The data provider states it is raw, unvalidated, and may contain errors or transmission delays.
