Both Generator training packs use reference-image tiles from the Geospatial Information Authority of Japan (GSI), Nagano City Omachi, October 13, 2019, Typhoon Hagibis. Source footage SHA-256 recorded locally: a112641a9335adc310f872963ce49a4e73d7a9451fe07fc06705286e32379ec2. This is a local provenance checksum, not one issued by GSI.

Training and evaluation tiles are separated within this one flight. Images are reference inputs; synthetic target coordinates have no provided image-to-3D correspondence. mixed240 uses 480 numeric examples; balanced288 uses 576. The released saved answers include newly generated numerical geometry and explicitly marked reused regression cases; they reuse reference evaluation images. No footage or image tiles are included in this repository.
Earlier documents described Omachi as evaluation-only for a retired observation task. That statement does not apply to these Generator training packs. No client footage was used in these checkpoints. Aso, Sannoudani, and other events mentioned in older experiments are not these models' training imagery.
