Geodetic network and Cartesian origins in Medellín
Inspect published geodetic control points, identifiers, types, review dates and links to official records. Also explore the five MAGNA Cartesian-origin areas in the Aburrá Valley to prepare a technical review of reference cartography.
The archive contains 1,089 control points across several municipalities and five origin areas, not an inventory exclusive to Medellín. Recorded reviews span 2010–2019 and 21 points have no date; the published “Disponible” status does not confirm their current condition. Reference locations and areas do not replace official records, transformation parameters or field verification. No specific reuse license is declared.
What does Geodetic network and Cartesian origins include in the Medellín geovisor?

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.
