Flood Hazard Zoning Maps for 100-Year Return Period in 79 Colombian Settlements

79 flood hazard zoning maps for a 100-year return period across Colombian population centers, showing low, medium, or high threat levels. The data is provided as raw, unvalidated geospatial information by www.datos.gov.co, with a last update timestamp of 2026-05-22 05:53:31. Columns include the_geom for geometry, AMENAZA for threat classification, and attributes for location (CENPOB, DEPARTAMEN, MUNICIPIO) and geometry (SHAPE_LEN, SHAPE_AREA).

Use Cases

• Classifying flood threat levels (AMENAZA) by settlement (CENPOB) using geospatial data (the_geom).
• Calculating total flood-prone area (AREA_TOT, SHAPE_AREA) per municipality (MUNICIPIO) and department (DEPARTAMEN).
• Mapping flood hazard zones (the_geom, RULEID) for a 100-year return period to support territorial risk management.

Strengths

• Covers 79 distinct population centers (CENPOB).
• Includes explicit flood threat classification (AMENAZA) as low, medium, or high.
• Provides geospatial geometry (the_geom) and area/perimeter calculations (SHAPE_AREA, SHAPE_LEN).

Limitations

• Data is explicitly unvalidated and may contain errors or inconsistencies, per the description.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; the description states updates are 'eventual'.
