ANLA geographic storage model

Preparing a MAG requires more than completing folders: each geometry, attribute, source and document must correspond to the applicable version and the actual study. We help environmental and geospatial teams organize that package, review consistency and preserve traceability before submission. The result is a better controlled internal process, not certification, official validation or a promise of acceptance by ANLA.

Verify the reference before production

The first task is to confirm the current instrument, its official source, status, version and verification date. We then build a matrix of objects, attributes, formats and evidence for the specific scope. This prevents a team from copying an old template or mixing requirements from different procedures. Interpretation questions remain visible for consultation rather than being concealed inside an automated rule.

We inventory layers, tables, appendices and owners. Every source records provenance, cutoff, usage authorization, original coordinate system and applied transformations. Objects are connected to chapters, plans and documents so a correction is not lost among versions. Naming conventions and change controls make it possible to reconstruct who changed an item and why.

Readiness controls

Review may cover directory structure, file presence, schemas, types, domains, required fields, identifiers, geometries, spatial extent, duplicates and consistency between manifest and content. Findings are assigned a severity and owner. A geometry error might allow a controlled technical correction; a missing source or inconsistency with the study requires a responsible team decision.

The local precheck processes a sample in the browser and flags observable elements against the registered version. It neither sends nor stores the file. If it produces GeoJSON, that output supports internal diagnosis and exchange: it is not an official MAG format. No tool result replaces professional review or ANLA's process.

The energy experience is shared with the energy-planning cluster rather than duplicated. It describes a method applied across twelve anonymized projects without publishing clients, files, decisions or private outcomes.

Ways to engage

We can audit a sample, support periodic closeouts or structure the entire control workflow. Scoping requires the procedure phase, reference version, approximate inventory and volume, working systems and target date. The proposal distinguishes preparation, correction, documentation and final internal review, with assumptions and acceptance criteria that the team can verify before submitting its package.
