LADM_COL-POT: preparing data without confusing transition and operation
A readiness guide for objects, sources, identifiers, relationships, determinants and metadata during the Decree 381 of 2026 transition.
LADM_COL-POT readiness should begin with inventory and correspondence, not bulk conversion. Identify territorial objects, legal and technical sources, owners, identifiers, scales, validity periods and relationships. Then compare that reality with the model that applies during the transition. This reveals gaps without presenting historical experience or a preliminary template as an extended operational schema.
Fix the source of truth before transformation
The Decree 381 of 2026 published by MinVivienda established a transition through 7 October 2026. This guide records the date but does not use a countdown. During the transition, prudent work focuses on inventory, governance, metadata and mapping rules while authorities consolidate the applicable instruments.
Build a correspondence table between the municipal inventory and the target schema: object, legal or technical source, current identifier, relationship, geometry, validity and owner. Mark what maps directly, what needs transformation and what requires an institutional decision. Do not regenerate identifiers or simplify relationships merely to fill a template. Test the mapping with parcels, determinants and planning actions of different complexity while retaining a link to the source register. During the transition, this table absorbs changes in the instrument without rebuilding the whole database or confusing readiness with formal operation.
Recommended sequence
- Verify. Inventory POT objects, determinants, acts, maps, documents, sources and owners.
- Map. Assign stable identifiers and record validity, scale, accuracy and status for every object.
- Prepare. Build a mapping matrix without forcing elements that do not yet have an equivalent.
- Check. Review geometry, relationships, domains and metadata on a representative sample.
- Close. Version rules and retain a decision log for future migration or adjustment.
Minimum control evidence
The technical preparation record should retain:
- legal source separated from cartographic interpretation.
- explicit temporal validity.
- scales and accuracy not mixed.
- reversible documented mapping rules.
What the diagnostic cannot promise
LADM-COL for cadastre and LADM_COL-POT are not interchangeable even when they share modelling concepts. Preparation does not create legal validity, resolve contradictions among acts or guarantee that a future delivery will be accepted. Historical municipal experience needs to be described as historical and separated from the model’s current state. Any official change requires another review of the mapping matrix.
