Export Centre

JSON is the lossless master format with schema_version, stable IDs, units, sources and quality states. CSV is a flattened view.

Catalogue JSON

All published circuits, every layout revision, milestones, public contacts, field evidence and sources. Reimports match by ID.

CSV Tables

Separate files for circuits, layouts (one row per revision), sources and evidence.

Planned · Stage 2

GeoJSON and SVG outlines are now downloadable from each circuit profile once geometry is approved. PNG and WebP artwork, elevation samples, profile PDFs and ZIP bundles with manifests and checksums need approved geometry first. GLB exports arrive only when a real approved scene with export rights exists.
