Lunar Pits Dataset v2 (Zero-Leakage & SPICE-Projected)

This dataset provides curated 224x224 and 256x256 Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) tiles representing confirmed lunar volcanic pits (caves/skylights) and geological control features.

Dataset Overview & Improvements in v2

Ground-Truth Precision (SELENE-PITS Source): All 278 true positive pits originate from the high-precision F1nnSBK/SELENE-PITS catalog, where every candidate coordinate was ray-traced using NASA SPICE kernels and auto-centered on the deep interior shadow core (sub-pixel accuracy, zero pointing drift).
Mined Hard Negatives: Includes 150 vetted hard negative samples (crater shadow rims, boulders, rille floors) mined from active false-positive areas to prevent visual confusions during planetary-scale scanning.
Negative Controls: 590 representative control tiles covering typical lunar mare basalt and highland terrain.
Leakage-Free Stratified Group Split: Partitioned strictly by geological host crater/region (e.g., Copernicus, Marius Hills, King, Mare Tranquillitatis) ensuring 0% spatial overlap across splits.

Dataset Splits

Split	Total Samples	Lunar Pits	Hard Negatives & Controls	Host Overlap
train	1,876	1,377 (augmented)	499	0%
validation	119	10	109	0%
test (Holdout)	247	115	132	0%

Data Schema

Each example contains:

id (string): Unique identifier (e.g. pit_lpa_12_rot90, hard_neg_copernicus_04).
label (int64): 1 for Lunar Pit, 0 for Negative Control / Hard Negative.
source_nac (string): LROC NAC Product ID.
host_crater (string): Geological host crater or lunar region.
center_lat / center_lon (float64): Lunar coordinates.
npy_data (list of list of float32): 224x224 normalized float32 height/radiance array.

Quickstart

from datasets import load_dataset
import numpy as np

ds = load_dataset("F1nnSBK/lunar-pits-dataset")
sample = ds["test"][0]

image_array = np.array(sample["npy_data"], dtype=np.float32)
label = sample["label"]
print(f"ID: {sample['id']} | Label: {'Pit' if label == 1 else 'Negative'} | Shape: {image_array.shape}")
