# LandsatQuake: A Large-Scale Dataset For Practical Landslide Detection

**Paper:** [LandsatQuake (ICLR 2025 Workshop on Machine Learning for Remote Sensing)](https://iclr.cc/virtual/2025/36761)  
**Authors:** Vihaan Akshaay Rajendiran, Amanda Roeliza Hunt, Gen Li, Lei Li

Identifying landslides from remote imagery is critical for rapid responses after landslide hazards and for assessing their environmental impacts. LandsatQuake is a benchmark dataset composed of 31 landslide inventories from 21 earthquake-prone regions across the world, covering a total area of 5.56 × 10⁷ km² and spanning the last 40 years. This dataset emphasises practicality by using satellite images acquired by Landsat — the only satellite system that has recorded Earth's land surface for over 40 years.

## ⚠️ Important: Do NOT use `load_dataset()`

HuggingFace's auto-parquet conversion does **not** work correctly for this dataset. It drops all bounding-box annotations and replaces filenames with hashes. Instead, **clone the repository directly**:

```bash
# Install git-lfs first: https://git-lfs.com
git lfs install
git clone https://huggingface.co/datasets/Vihaanakshaay/LandsatQuake
cd LandsatQuake
git lfs pull
```

## Format Details

### Images
- **Size:** 224 × 224 pixels, RGB, JPEG
- **Source:** Landsat satellite imagery
- **Naming convention:** `{year} {location} {pre/post}-earthquake_patch_{x}_{y}.jpg`

### Object Detection Labels (Pascal VOC XML)
Each image has a paired `.xml` file in Pascal VOC format with bounding boxes:
```xml
<annotation>
  <size><width>224</width><height>224</height><depth>3</depth></size>
  <object>
    <name>landslides</name>
    <bndbox><xmin>141</xmin><ymin>201</ymin><xmax>150</xmax><ymax>210</ymax></bndbox>
  </object>
  <!-- ... more objects ... -->
</annotation>
```

### Instance Segmentation Labels (YOLO TXT)
Each `.txt` file contains normalised polygon coordinates:
```
0 x1 y1 x2 y2 x3 y3 ...
```
Where `0` = landslides class and coordinates are normalised to [0, 1].

## Quick Start (Python)

```python
import os
import xml.etree.ElementTree as ET
from PIL import Image

def parse_voc_xml(xml_path):
    """Parse Pascal VOC XML and return list of (class, xmin, ymin, xmax, ymax)."""
    tree = ET.parse(xml_path)
    boxes = []
    for obj in tree.getroot().findall("object"):
        cls = obj.find("name").text
        bb = obj.find("bndbox")
        boxes.append((
            cls,
            int(bb.find("xmin").text), int(bb.find("ymin").text),
            int(bb.find("xmax").text), int(bb.find("ymax").text),
        ))
    return boxes

# Example: load a training image with its annotations
img = Image.open("LandsatQuake/train/1987 Sichuan pre-earthquake_patch_2464_11872.jpg")
boxes = parse_voc_xml("LandsatQuake/train/1987 Sichuan pre-earthquake_patch_2464_11872.xml")
print(f"Image size: {img.size}, Landslide boxes: {len(boxes)}")
```
