Environmental noise in Medellín
Explore modeled isophone bands across the Aburrá Valley by source and period: road traffic, airport, metro system, industry and total noise, by day and by night. Inspect each band’s decibel range and compare sources on the map.
Reference modeling from September 2022, not current measurements or a regulatory-compliance assessment. Coverage spans the Aburrá Valley municipalities; the viewer queries the service within the visible area with scale-dependent generalization and potentially partial results.

How to use itHow to use the map
- Open the viewer with this theme’s first layer enabled. Search a neighborhood or enter coordinates as latitude, longitude.
- Enable other layers in the theme and zoom in. Detailed cadastral layers require a close scale to keep queries bounded.
- Select a feature on the map or in the Results list. Check its attributes, retrieval time and any partial-result notice.
- Choose a field and exact value to filter the layer. Export includes only received results, with attribution and dates; it does not download the whole municipality.
Sources, dates and limits
Each source’s verification date appears in the table. Retrieval time is not the data update date. Small city-wide layers use the full extent; larger layers depend on the visible area. Reference publications retain their original retrieval date. Each response contains up to 500 features and 2 MB. Reference publications load matching pages, up to 5,000 features and 8 MB per query. External services may return partial samples, identified in the viewer.
