 # Tree Distribution Shift — Satellite Tree Detection (COCO + HF Datasets)
 
-This is a dataset containing ~30K COCO tree crown annotated satellite image tiles of 400x400 px dimensions. These annotations come from all states in India and California in the United States. 
+This is a dataset containing ~30K COCO tree crown annotated satellite image tiles of 400x400 px dimensions. These annotations come from all states in India and California in the United States.
 This dataset is organized as **configs** (distribution shift benchmarks). Each config provides **three splits**:
 
 - `train` — 90% of the in-distribution pool
-- `val` — 10% held-out from the in-distribution pool (same images appear as `ood_test` in the paired config)
-- `ood_test` — held-out portion from the out-of-distribution pool
+- `id_test` — 10% held-out from the in-distribution pool
+- `ood_test` — out-of-distribution pool (base configs use the full OOD pool)
 
 ## What is a config?
 
-A **config** fully defines a benchmark setting (e.g., country shift, biome shift, region shift).  
+A **config** fully defines a benchmark setting (e.g., country shift, biome shift, region shift).
 When you select a config, you automatically get:
 
 - `train` split
-- `val` split
+- `id_test` split
 - `ood_test` split
 
 No filtering or custom split logic is required.
 
 ## Shared test sets
 
-Configs come in pairs. For every pair, the test portion of each pool is **constant** regardless of whether it is used as `val` (in-distribution) or `ood_test` (out-of-distribution). For example:
+Configs come in pairs. The in-distribution split is always 90/10 train/id_test, and base configs use the full opposing pool as `ood_test`.

-The "10% of India" set is identical in both rows, and so is the "10% of US" set.
+Few-shot variants (`__fs1`, `__fs10`, `__fs100`, `__fsall`) move K images from `ood_test` into `train`.
