TerraDiT-data

Derived conditioning artifacts for training and evaluating TerraDiT / TerraDiT-Ω. No imagery is included: tiles come from lcybuaa/Git-10M at revision 29f192b8d2aa28b5d4d8c8d7f0f608cdc61fb52f; every metadata row's hf_idx indexes the train split of that snapshot.

Contents (mirrors the data_root layout the code expects)

path	rows / size	description
metadata/alpha.json	2.0M	img_name, Google_location, latitude, longitude, hf_idx (no Git-10M text; captions are read from your Git-10M copy)
metadata/sigma.json	330k	cities subset used for TerraDiT-Σ
metadata/omega.json	2.0M	tiles with instance geometry (TerraDiT-Ω)
splits/random/	14,932 tiles	held-out random test split: metadata.json, inst_metadata.npz, range_plus.npz
splits/spatial/	14,387 tiles	geographically held-out test split (same files)
splits/dense/	3,426 tiles	random tiles with >= 15 instances (strict subset)
osm/tag_vocab.pt	1,711 tags	OSM "key value" tag -> id
instance_metadata/inst_metadata.npz	2.1 GB	per-instance geom_type, point_xy, bbox_xyxy, verts_xy(+ptr), tag_ids(+ptr), per-tile tile_inst_start/end
points.pack	1.2 GB	256x256 OSM tag-id rasters per cities tile (Σ point supervision)
range_plus/omega.npz	~5 GB	RANGE+ embeddings [2.0M, 1280] fp16 + locs [N, 2] (lon, lat), row-aligned with metadata/omega.json
range_plus/sigma.npy	~0.9 GB	RANGE+ embeddings [330k, 1280] fp16, row-aligned with metadata/sigma.json

Not included: SDXL latents (build with scripts/encode_latents.py) and DINOv3 weights (obtain from Meta).
