🛰️ HSI Datasets Collection

A comprehensive collection of 24 publicly available Hyperspectral Image (HSI) datasets curated for research in hyperspectral image classification, land use/land cover (LULC) mapping, and remote sensing deep learning benchmarks.

Total Size: ~20.1 GB

📖 Dataset Description

Hyperspectral imaging captures data across hundreds of narrow spectral bands, enabling fine-grained material and land cover discrimination beyond what RGB or multispectral sensors can achieve. This repository consolidates 24 widely-used HSI benchmark datasets in a single place, covering a variety of sensors (AVIRIS, ROSIS, Hyperion, CRISM), geographic regions (USA, Europe, Asia, Mars), and scene types (urban, agricultural, coastal, planetary).

All datasets are stored in .mat format (MATLAB-compatible), making them directly loadable with scipy.io in Python.

📦 Included Datasets

All datasets are hosted on the HuggingFace Hub: Tanishq165/HSI_Datasets

🚀 Loading the Data

Install dependencies 

pip install huggingface_hub scipy numpy h5py scikit-learn pyyaml matplotlib

Load a single dataset (via project loader) 

from utils.data_loader import DatasetLoader
import numpy as np

loader = DatasetLoader(use_cache=True)

# Auto-downloads from HuggingFace Hub on first use
hsi_cube, labels = loader.load_dataset("Indian_Pines")

print(f"HSI Cube shape : {hsi_cube.shape}")
print(f"Labels shape   : {labels.shape}")
print(f"Num classes    : {len(np.unique(labels)) - 1}")  # excluding background

Download all datasets 

from huggingface_hub import snapshot_download

local_path = snapshot_download(
    repo_id="Tanishq165/HSI_Datasets",
    repo_type="dataset"
)
print(f"Downloaded to: {local_path}")

📐 Data Format

Property Details
File Format .mat (MATLAB / scipy compatible)
HSI Cube Shape (Height × Width × Spectral Bands)
Ground Truth Shape (Height × Width) — integer class labels
Background Class Label 0 represents unlabeled/background pixels
Value Range Reflectance values (varies per dataset; typically float32 or uint16)

🔬 Applications & Use Cases

  • Hyperspectral Image Classification (HSI) — pixel-wise or patch-based
  • Land Use / Land Cover (LULC) Mapping
  • Benchmarking deep learning architectures — CNNs, Vision Transformers (ViT), Mamba/SSMs, Graph Neural Networks
  • Transfer learning & domain adaptation across HSI scenes
  • Multi-sensor data fusion (e.g., HSI + LiDAR for Trento/Augsburg)
  • Planetary surface analysis — NiliFossae, Utopia and Holden(Mars CRISM data)
  • Spectral unmixing and abundance estimation

⚠️ Data Loading Notes

  • Auto-transpose: The loader automatically detects and transposes data to (H, W, Bands) if needed.
  • Background class: Class 0 is always background/unlabeled and excluded from training.
  • v7.3 MAT files: Some datasets use HDF5-based .mat format. The loader falls back to h5py automatically.
  • Class imbalance: Many datasets have highly imbalanced classes (e.g. Indian Pines, Houston18). Consider weighted loss or balanced sampling.
