ANLA MAG checklist: verifiable preparation before precheck

An effective MAG checklist reviews three levels separately: whether the package matches the applicable instrument and version, whether the technical structure contains the expected classes and domains, and whether the content traceably represents the project’s studies and obligations. Passing the first level does not resolve the other two. Review needs to retain findings, owners and correction evidence.

Fix the source of truth before transformation

The regulatory anchor is Resolution 2182 of 2016 and the MAG package published by the authority. Consult ANLA’s official instruments, permits and procedures section and confirm the current package before starting. An old local copy must not be treated as current merely for convenience.

Version the template, dictionary, local rules and matrix that determines which classes apply to the procedure as one set. For every element, record required, conditional or out of scope and cite the evidence behind that decision. Run checks on a hashed copy, retain findings by class and object, and repeat the review on the final package. An accepted exception should name its owner, rationale and date. This record separates a justified absence from missing data and prevents a checklist for another version from being reused by inertia.

Recommended sequence

1. Verify. Record instrument, version, download date, procedure scope and technical owner.
2. Map. Compare structure, names, types, domains and required status with the official package.
3. Prepare. Review geometry, CRS, duplicates, gaps and spatial relationships with documented rules.
4. Check. Link layers to chapters, appendices, dates and sources in the relevant environmental study.
5. Close. Correct a controlled copy and repeat the precheck until every finding is closed or accepted.

Minimum control evidence

The technical preparation record should retain:

• retained official package and hash or version.
• required-elements matrix by scope.
• domains and nulls reviewed with judgement.
• lineage from study to layer and feature.

What the diagnostic cannot promise

GeoSAT’s precheck is an unofficial aid. It is not VALIDA, does not replace ANLA controls and does not guarantee filing or acceptance. A result with no findings only means that the local rules executed found no signals; a content, interpretation or scope issue may still exist. Visitor files must remain local unless explicit consent is given to share a bounded summary.

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.
