### Dataset Summary

![](https://huggingface.co/datasets/alkzar90/rock-glacier-dataset/resolve/main/assets/rock-glacier-portrait2.png)

Rock Glacier Detection dataset with satelital images of rock glaciers in the Chilean Andes. 

### Supported Tasks and Leaderboards
- `image-classification`: Based on a satelitel images (from sentinel2), the goal of this task is to predict a rock glacier in the geographic area, if there any.
- `image-segmentation`: ...

### Languages
Spanish

## Dataset Structure

### Data Instances

A sample from the image-classification training set is provided below:

```
df = load_dataset("alkzar90/rock-glacier-dataset", name="image-classification")

df["train"][666]

> {'image': <PIL.PngImagePlugin.PngImageFile image mode=RGBA size=128x128 at 0x7FB2EC58C6D0>,
 'labels': 0,
 'path': 'train/cordillera/1512.png'
}
```

A sample from the image-segmentation training set is provided below:

```
df = load_dataset("alkzar90/rock-glacier-dataset", name="image-segmentation")

df["train"][666]

> {'image': <PIL.PngImagePlugin.PngImageFile image mode=RGBA size=128x128 at 0x7FB2EB7C1160>,
 'masks': <PIL.PngImagePlugin.PngImageFile image mode=RGBA size=128x128 at 0x7FB2EC5A08E0>,
 'path': 'train/cordillera/1512.png'}
```

### Data Fields

The data instances have the following fields:

- `image`: A `PIL.Image.Image` object containing the image. Note that when accessing the image column: `dataset[0]["image"]` the image file is automatically decoded. Decoding of a large number of image files might take a significant amount of time. Thus it is important to first query the sample index before the `"image"` column, *i.e.* `dataset[0]["image"]` should **always** be preferred over `dataset["image"][0]`.
- `labels`: an `int` classification label.

Class Label Mappings:

```json
{
  "cordillera": 0
  "glaciar": 1,
}
```
