Decree 381 of 2026: organising determinants as traceable data
How to inventory determinants, sources, geometry, validity, scale and conflicts during the regulatory transition without turning GIS into legal advice.
Organising territorial determinants as data requires retaining the link between each geometry and its competent source: act, technical document, date, validity, scale, owner and interpretation. A map supports overlay and query, but it does not decide hierarchy or resolve legal contradictions. Its role is to make sources, overlaps, gaps and conflicts visible for assessment by the competent team.
Fix the source of truth before transformation
Decree 381 of 2026 as published by MinVivienda is in transition through 7 October 2026 according to the verified register. The date should appear as context, not as a countdown or sales pressure. Readiness can progress during the transition when each layer states its source, status and limitations and the team checks the current instrument before adoption decisions.
Model every determinant as a record linked to its act and competent authority, including validity, scale, production method, original geometry and interpretation owner. If a boundary is digitised or adjusted, retain the received version and describe the operation. Turn overlaps into review cases with visible sources instead of resolving them by drawing order. Test the inventory with determinants from different scales and dates and document gaps. This history gives technical, legal and territorial teams the same evidence during the transition without turning the map into an automatic decision.
Recommended sequence
- Verify. List determinants and competent sources without inferring geometry from names or summaries.
- Map. Capture act, date, validity, scale, accuracy, owner and supporting URL or file.
- Prepare. Retain original geometry and document any digitisation, adjustment or generalisation.
- Check. Analyse overlaps and gaps as findings rather than automatic legal decisions.
- Close. Publish versions with history and a technical, legal and territorial review workflow.
Minimum control evidence
The technical preparation record should retain:
- act and authority linked to each object.
- visible validity and version.
- warnings for scale differences.
- conflicts assigned to a review owner.
What the diagnostic cannot promise
A geospatial layer does not replace the act or prove that its interpretation is definitive. Overlaying data at different scales can create apparent boundaries, and absence from a portal does not establish non-existence. GeoSAT’s diagnostic assesses readiness and traceability; it does not provide a legal guarantee, adopt determinants or replace the jurisdiction of authorities and legal teams.
Review the specialised GeoSAT service to define scope and the related cluster to identify interoperability, environmental or territorial dependencies. This guide is informational; service pages explain evidence, tooling and an appropriate next step without promising an official decision.
