Flood Hazard Zonation for 25 Population Centers in Colombia with 20-Year Return Period

A 20-year return period flood hazard zonation for 25 population centers in Colombia, showing existing threats classified as low, medium, or high. The dataset is published by www.datos.gov.co and was last updated on 2026-05-22 05:49:05. It contains geospatial and administrative attributes for each area, including municipality and department.

Use Cases

• Classifying flood hazard levels (AMENAZA) for specific population centers (CENPOB) using geospatial boundaries (the_geom).
• Aggregating total flood-prone area (AREA_TOT, SHAPE_AREA) by administrative unit (MUNICIPIO, DEPARTAMEN).
• Mapping flood risk zones (AMENAZA) against geometric perimeters (SHAPE_LEN) for spatial analysis and visualization.

Strengths

• Contains explicit hazard classification (AMENAZA: baja, media, alta) for risk modeling.
• Includes both geometric (the_geom, SHAPE_AREA) and administrative (MUNICIPIO, DEPARTAMEN) attributes for joined analysis.
• Data is provided in multiple machine-readable formats (CSV, JSON, XML, RDF).

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• The description states data may contain errors, inconsistencies, or transmission delays and is not validated for legal evidence.
• Update frequency is described as 'eventual' (ocasional), so freshness should be verified.
